Does the Obd Give You a 12v Read Leaf

Overview

Leafage Spy, formerly the Leaf Spy/Leaf Spy Pro, is a software programme that runs on nigh Android phones. The program displays information from the Auto-CAN bus. The information is read using a Bluetooth OBDII scanner plugged into the Foliage'southward OBD port and a Bluetooth connexion to the phone. The software was written by Jim Pollock (Turbo3 on the mynissanleaf forum). The latest version tin be downloaded hither. 3 versions are available. 1 is free and gives the basic battery info.
The program provides:

• Gids as a raw number or a percentage of 281 (the usual maximum reading of a new Foliage)
• The percent state of charge (SOC)
• Information on the voltage of each of the 96 cell pairs in the battery pack
• Which cells take their shunts currently active (this is the battery balancing) – there is some disagreement about which setting correctly shows which cells have shunts agile. Gary Giddings believes information technology is 4812, GregH is sure information technology is 8421. You can cull which guild is used on the Settings Screen of the application.
• The maximum departure in cell pair voltages (tells you whether the pack is well balanced or not)
• The voltage of your 12 volt battery (requires calibration with a voltmeter)
• The readout from each of the temperature sensors in the battery pack (4 sensors for 2011-2012, 3 for 2013)
• Tire pressures with optional warning if they go below a ready value

Additional calculated values:

• kWh remaining in the Leaf battery pack
• Watt hours used past the Leaf since yous last reset it
• Temperature divergence between highest and lowest temperature reading from battery pack sensors
• Distance to empty based on your personal settings for efficiency (miles per kWh) and the corporeality of energy you want to leave equally an emergency reserve

In addition, there is a logging function and then you tin monitor the modify in parameters every one minute to ane hour (time interval tin can be set by user). The log file tin so be imported to a spreadsheet so you can graph the changes over fourth dimension.

Required Hardware and Software

In gild to use the Leaf Spy/Leaf Spy Pro, you will need the post-obit:

Clone ELM327 Bluetooth Scanner

There are a number of different ELM327 Bluetooth scanners available on the cyberspace for $10-25. While most are likely to piece of work with your phone, in a few cases a user had to buy a 2nd one from a different source, either because of an incompatibility betwixt the scanner and the phone, or in one case because the product was defective. In that location are two reports that the ELM327 scanner from the eBay seller "newlauch" did not work. Some scanners using v2.1will not piece of work with the app. Turbo3 is suggesting to stay away from all scanners using v2.1.
The following ELM327 products have been reported to piece of work:

• V1.5 Super Mini ELM327 Bluetooth OBD2 OBD-II CAN-Bus Diagnostic Scanner Tool – At least one confirmed to use v2.1 🙁
• BAFX Products (TM) – ELM 327 Bluetooth OBD2 scan tool
• AGPtek® Super Mini ELM327 V1.5 Bluetooth OBD2 OBD-2 CAN-BUS Auto Diagnostic Scanner Tool
• Simvalley™ Mini ELM327 Bluetooth OBD2 Car Diagnostics Scanner with Power Switch for Android
• Excelvan ELM327 v1.5 Bluetooth Mini Pocket-size Interface OBD2 Scanner Adapter Torque Android
• Newest Elm327 Bluetooth V1.5 OBD2 OBD 2 Automobile Diagnostic Scanner Mini Adapter
• PLX Devices Kiwi Bluetooth Wireless Trip Computer and OBDII Scanner
• Vgate ELM327 Bluetooth Browse Tool OBD2 OBDII Scanner for TORQUE APP ANDROID – At least i confirmed to use v2.1 🙁– Tin can be taken autonomously easily and modified

The Simvalley that has the on and off switch and Newest ELM 327 do NOT piece of work with the HTC One S. Using the Turbo 3 app.
The Vgate ELM327 can be modified to switch it from "ever on" to only on when car is in On mode or Ready mode (although from the testing LEAFfan has done, this does not appear to exist necessary):
To catechumen the "chubby" dongle to operate off of the switched 12v power, rather than always on, simply:
0. Fully test the unmodified dongle first.
1. Cutting out or remove the label to expose the 4 screws. I cut out iv small disks of the label, one over each spiral, as is shown on the first post of this thread.
2. Remove the 4 screws with a medium Philips screwdriver. Clean the extra plastic out of each screw's threads.
3. Lift the lid straight upward and off the bottom. Removing the OBD connector from the bottom might brand the next footstep easier. I unremarkably unplug the wire's connector from the lath.
four. Carefully un-solder the wire from pivot xvi, and solder it to pin eight. Audit your piece of work.
5. Reassemble. Supplant the OBD connector (if removed), making sure that the wires are well clear of the Bluetooth antenna.
6. Replace the peak, and the 4 screws, turning the screw counterclockwise until it clicks, then clockwise to screw it in (not too tight).
vii. Mark or label the dongle to indicate what modification you fabricated.
8. Exam the modified dongle, and mark information technology as tested.

Extension Cablevision or Splitter Cable

You lot probably want to use an extension cable or splitter cable so that you don't have to keep plugging and unplugging the OBDII Scanner considering:

• The Leafs OBD port is not designed for frequent use, so you want to plug in a cable which tin be replaced if the socket at the end where the scanner is plugged in wears out
• You don't desire to damage your OBD port, which is as well used by Nissan Service during the Bombardment Pack check and probably to diagnose and repair other issues
• If you plan to run a Gid Meter or similar device simultaneously with the Leaf Spy/Leaf Spy Pro you will demand the splitter cablevision. Otherwise, an extension cable will piece of work fine. If the end of the cable that plugs into the OBD port has the cable coming straight downwardly the cable may interfere with your access to the pedals. Use caution here. A better pick would be to accept the cablevision come out the side of the socket as is done with the original Gid meter. If you are unable to locate a splitter with a right side plug, a expert option would probably be to combine an extension cable with a right side plug forth with a splitter cable. The combination would provide better clearance where the extension cable plugs into the OBD port, and less actress cablevision to deal with after the split. If you lot don't need the splitter, the short extension cable alone will help to protect your OBD port from frequent plugging and unplugging.

JPWhite reminds us that proficient cable direction is important for both aesthetics and condom. The 3.3 feet extension cable listed below that he purchased has a correct angled cable connexion at the OBD interface (which keeps it away from his feet) and tin exist fastened to the underside of the drivers side dash using Ativa Cable Clips or like from Amazon. See the following routing he did from the OBDII outlet to the eye console where he keeps the ELM327 in a cup holder:

The cablevision tin can be inserted and removed from the clip multiple times. Then if you lot are concerned the dealer service dept volition question having a cablevision plugged into the ODB Port, the cable, ELM327 and Android telephone tin can all be removed from the motorcar in xxx seconds and they are none the wiser.

Right angle OBDII male to female 16 pin extension cables

• Generic 100 CM/3.3 anxiety – Fulfilled by Amazon – $9.47 – Tested by JPWhite; optimal considering the cablevision exits toward the front of the car, away from your legs. This cablevision is also thinner and thus more pliable which helps with cable routing.

Note: other cable extensions removed from this listing as they either have thick cables which are hard to route or the cablevision exits the OBD connecter in a management that interferes with the prophylactic performance of the Leaf

OBDII male person to female person 16 pin splitter/Y cables

• Generic 1 human foot – Fulfilled by Amazon – $10.10 – Tested past Stoaty; he recommends this splitter cable along with the extension cable tested by JPWhite
• ZITrades branded three feet – Fulfilled by Amazon – $20.35 – Tested by Stoaty

Optional Telephone Holder

You may want to go a holder for your phone so yous can attach it in a convenient and visible place. I possible piece of equipment suggested by a forum member is here. While the photos are better on that site, a cheaper price is here.

Leaf Spy/Leaf Spy Pro

The latest version of the application. Notation that the version with "FS" at the terminate is the fullscreen version (no android card at superlative of screen (that is the merely difference).

Setup

Download and Install the Leaf Spy/Foliage Spy Pro
If you have a cell phone that is activated and has WiFi active, you tin go straight to the dropbox business relationship and go the latest version. Otherwise, you volition need wireless access through a wireless router or at a business that has WiFi. Brand certain that WiFi is active on your phone (press Settings button–lower left button on Fusion 2 phone–then select Settings -> Wireless and Networks -> check box for Wi-Fi). Click on Wi-Fi Settings and select a Wi-Fi Network to connect to. If the connection is Secured, you will have to enter a password. If you need more detailed information on getting started with an Android phone see this thread.
Pairing
1. Plug the ELM327 device into the OBD connector. (The OBD connector is under the dash, slightly to the left of the steering cycle.) Plough the machine on every bit if to bulldoze it (to "Ready" style, with the green car and double concluded pointer sumbols). If the ELM327 device has a button, push it to ability it on.
2. Ability on the phone, open Settings, Wireless and Networks, tap Bluetooth, and turn Bluetooth On.
3. Under Bluetooth Settings make certain the Device is Discoverable. If there is an option for how long to make the device discoverable, set v minutes so you volition have time to make the connection
4. If your device is not listed, Search For Devices (at the bottom of the screen).
Note: Since the ELM327 device MIGHT simply be discoverable for a minute or so after it is plugged in, you might have to unplug information technology and plug it in again. Yep, some do wobble later they are plugged in, but that might just be the socket in the automobile, and it is normal, I think.
5. After beingness discovered, attempt to Pair with the device. When it asks for the pairing lawmaking, showtime try 1234, even if the instructions say 0000 (some instructions are incorrect). If that doesn't work, attempt it again, and fifty-fifty a third time. Finally try the other less common codes, the 0000 and then the 6789. Keep trying until you have a successful pairing hither. Some accept reported 6-8 tries to go a successful pairing, even using the correct pairing code.
half dozen. One time it is Discovered and Paired hither past the telephone, it should show up in the Select OBDII list (from the "Carte" icon) in the app. Notation: the pairing only needs to be done once.
More than information on troubleshooting pairing problems can be constitute in this thread.

Precautions

There are several precautions you should observe when using the Leaf Spy/Leafage Spy Pro with the ELM327 Bluetooth scanner:

• Every bit mentioned in a higher place, avoid plugging and unplugging the ELM327 scanner multiple times, as you could damage your OBD port
• Be careful with the routing of whatsoever extension/splitter cables every bit your feet could get caught in them and crusade an blow
• Be actress careful when driving and looking at the telephone to see data. One forum participant who idea he was being careful almost rear-concluded another machine. Turning on logging and analyzing the data later is safest.
• While the application has been successfully used while driving by several testers (and no problems were encountered with performance of the Foliage) use at your own risk
• There is conflicting data about whether leaving the ELM327 scanner plugged in draws enough current to run down the 12 volt battery. At that place are a couple of reports of batteries going down to eight volts when the scanner was plugged in overnight. Even so, ane of the reporters did more testing and concluded that the problem was related to having the ELM327 plugged in and having the telephone on with the Leaf Spy/Leaf Spy Pro running and communicating with the scanner. When he exited the Leaf Spy/Leaf Spy Pro, he found no significant subtract in voltage for the 12 volt battery. Since then several other people have reported leaving the ELM327 plugged in for days to weeks at a time without changes in battery voltage. It is recommended that y'all only practice this if you will be charging on most days (that is when the 12 volt battery volition be charged). Unplug the ELM327 (or plow off if you take modified yours to allow this) if you will exist leaving your Leaf for a longer period of fourth dimension.
• W A R N I Due north Thou for those who accept a modified ELM that connects to the EV-Can instead of the CAR-CAN. Version 0.26 and higher volition non work on an ELM modified to run on the EV-Can. It volition go stuck at footstep xv and not go to the Connected state.
• The LeafDD cannot be used simultaneously with the Leaf Spy/Foliage Spy Pro. You should non have two active devices on the same OBDII Can at the same time fifty-fifty if they are on different CANs (EV,CAR). Remove one of them. WattsLeft is totally passive so is not a problem when using this app.

Pedagogy Manual

Overview

The Leaf Spy/Leaf Spy Pro can receive information from the Leaf nether either of two conditions:

• Leaf is in Set Mode (i.due east., you can drive it)
• One or more of the iii nuance accuse lights is on/flashing (i.eastward., during charging or for about 5 minutes later on you have set a charging timer)

You can get the Leaf into ready mode past:

• Human foot on restriction and press ON button (key in auto)
• Foot off brake and printing ON button twice

Y'all can go the nuance status lights to go active by:

• Pressing timer override button
• Unplugging and replugging charge cable
• Timer charge starts or remote accuse activation

The application has iv data screens and a settings screen:

• Screen 1 displays the cell pair voltages and battery pack temperature sensors
• Screen 2 tin can be toggled betwixt ii different screens (2A and 2B). Screen 2A displays a histogram of the jail cell pair voltages showing the number of cell-pairs at each specific voltage. It should be shaped approximately like a bell bend. Screen 2B displays a color coded bar graph of the four temperature sensors. Select Screen 2A by tapping on the top half of the screen; select Screen 2B by tapping on the bottom one-half of the screen.
• Screen 3 displays SOC%, Gids, usable kWh remaining in the pack, energy used since last reset, bombardment pack temperature (selection of minimum, maximum, or average), and distance to empty (DTE) based on your selected efficiency
• Screen 4 displays approximately the same information as screen 3, except that information technology uses graphical elements and shows the individual battery pack temperature sensor readings. It also has motor RPM and readings from the four tire pressure sensors
• The Settings Screen allows you to customize the application – select imperial or metric units, set up screen colors, lock to portrait or landscape mode if desired, enable logging, calibrate the 12 volt battery voltage, and debug.

Navigation

• When you start the Foliage Spy/Leaf Spy Pro, the awarding will attempt to connect with the ELM327 that you lot paired with during setup. You will see a sequence of messages during the process: "Waiting 4 BT…" (if Bluetooth was not already enabled on your phone or tablet) => "Waiting 4 ELM" => "Service Start" => " Waiting 4 Leaf" => "Connected". If this is the get-go fourth dimension the app has tried to connect to an ELM there will be a message "Select OBDII".
• There is also "Offline" way. To enter Offline mode:

1. Start app and make sure "Motorcar Enable Bluetooth" checkbox is non checked on Settings/Arrangement panel
2. Get out app
3. On Phone/Device turn off Bluetooth
4. Commencement app and yous will get the message "Do you want to Enable Bluetooth?"
5. Respond "No"
6. You are now in "Offline" mode. Since Bluetooth was off and yous did non permit the app to plough it on the app can not communicate with the ELM.

• The four screens are represented by iv small dots in the lower left hand corner of the screen. The open circle indicates the currently selected screen. To change to the screen to the right of the electric current screen, swipe the screen horizontally from correct to left with your finger. A left to right swipe moves to the screen to the left of the current screen. Notation that the swiping wraps around from last screen to first screen or vice versa. Alternatively, tapping the screen indicator in the lower left corner of the screen steps to the next screen. A tap and concur will step dorsum to the previous screen.
• Screen ii can exist fix to one of two choices: Voltage Histogram or Battery Pack Temperature bar graph. Tap the screen to toggle between them.
• To access the Settings Screen, press the Settings push button on your telephone (usually the lower left button), so tap Settings. To exit the Settings Screen, press the back button on your phone (normally the 2d push button from the right).
• The Dorsum push button will get out the application if pressed from Screens 1, 2 3 or 4.
• When you restart the Leaf Spy/Leaf Spy Pro, the last values from the previous session are displayed until you connect to the ELM327 scanner and receive new data.

Screen 1

The red bars represent those cell pairs that have the shunt active to bleed off some of the stored energy and balance the battery pack. This is still a work in progress.
The Approximate Remaining Battery Capacity % (the value in parenthesis between the AHrs value and the Battery Health value at the height of the screen) is just the AHr rating divided by a constant that the user tin alter in Settings to represent what a new bombardment would have. Each Leaf is a piffling different so you lot tin can not utilize one abiding for all. Still, there must exist a value used for this calculation, then the default is the value where nigh gen 1 Leafs would be <=100%.

Logging

• Yous practise not need a micro SD card installed in the phone in guild to practise logging
• The log file can be accessed using the File Explorer app on your phone. It will be in a binder named "LEAF_BT_CAN" and will be named "BatLog.txt"
• One way to transfer the log file to your calculator is to install the free Dropbox awarding through the Google Play app on your phone. If phone is not activated, you will need a WiFi connection (such as through your wireless router)
• The full resolution SOC and AHr are saved in the log file. For example, the log shows SOC=800065 afterwards a accuse to eighty% and a AHr=616115. You demand to dissever each of them by 10,000 to get SOC% and AHr.

The Foliage EV-Can charabanc must be active and the app must receive good data to a pack voltage request for a log event to have place (given that the selected interval has occurred or the forcefulness logging button was pressed).
The EV-CAN bus is agile when:

• I or more of the three dash accuse lights is on/flashing.
• Leaf is in Ready mode

You can get the nuance status lights to go active by:

• Pressing timer override button
• Unplugging and replugging accuse cable
• Timer charge starts or remote charge activation

You can get the Leaf into ready manner past:

• Foot on brake and press ON button (key in car)
• Foot off brake and press ON push twice

Hither is a screenshot of the log data imported into a spreadsheet. Note that the columns for Pack Temperatures 2 and 3, and the columns for Cell Pairs 2-95 have been removed to make it easier to see the data structure:
