Introduction

The Abrites Diagnostics for Tesla is an online server based diagnostic software. The current support list includes the “Model 3”, “Model S” and “Model X” vehicles.
In order to operate the software requires you to have an AVDI interface, a Windows based PC with Windows 7 or later version of the Windows OS and a stable Internet connection.
The tool’s purpose is to allow you to perform standard and advanced vehicle diagnostics starting with module identification, reading and clearing of diagnostic trouble codes  (DTCs) and live data monitoring,as well as advanced operations such as service functionality and more.
The software is in constant development and its functionality is ever growing. The intention is for the Abrites Diagnostics for Tesla to be used by automotive specialists but it  is simultaneously designed in such a way that is accessible to enthusiasts as well.

Installation

The “ABRITES Diagnostics for Tesla” is installed together with the rest of the Abrites diagnostic software applications when the installation files are received.
You could easily identify it by the Internet connectivity symbol as shown here:

Using the Abrites diagnostics for Tesla

The ZN072 ABRITES cable set for Tesla Model S/X and Model 3 is used when connecting to all Tesla models.

The ZN072 cable set consists of:
CB014 – a cable used for Tesla Model 3 – it has two connectors for the connection
ZN071 – a cable for Tesla Model S/X, used to connect using one connector under the central control panel
ZN072 – a set that consists of a CB014 and ZN071 cables.

When connecting to a Tesla vehicle it is extremely important to adhere to the following steps in order to avoid possible damage to the vehicle and your AVDI and PC.
Here is a list with the steps you MUST take before beginning work on a Tesla Model 3.
These must be completed before you connect the CB014 cable (part of the required ZN072 cable set).

1. Disconnect any charging cable

2. On the touchscreen, power off the climate control system, and wait at least 30 seconds for the climate control system to completely shut down

3. Make sure the vehicle is in Park

4. Fully lower all door windows to avoid glass shatter and door lockout conditions

5. Open the LH and RH rear doors, and then pass a shop towel halfway through each door striker to prevent the latch from securing

6. Remove the 2nd row lower seat cushion. See Seat Cushion – Lower – 2nd Row (Remove and Replace)

7. Remove the rear underhood apron. See Underhood Apron – Rear (Remove and Replace)

8. On the touchscreen, touch Controls > Safety & Security >Vehicle Power > Power Off
   Caution: Do not proceed until the climate control system has been powered off for at least 30 seconds.
   Do not disconnect 12V power while the climate control system is operational

9. Loosen the nut that attaches the 12V battery negative cable to the battery, and then disconnect the cable from the battery

10. Remove the foam cover from the RH side of the penthouse (back seats)

11. Disconnect the electrical harness from the high voltage controller connector.
    Note: The HV battery positive connector and negative connector open with a clunking sound. This is normal.

Once all of the safety measures are done (shutting off vehicle, lowering the windows, disconnecting the battery, etc), you can proceed with removing the plastic covers under  the steering wheel so that you can gain access to two connectors that we use to communicate with. The following is done on the Tesla Model 3. The photos below show the process on Tesla Model 3:

This is the main plastic cover that needs to be taken off so you can gain access to the connectors of the BCM module

This is the BCM connector that the CB014 adapter is connected to.

This is what the connection looks like after CB014 is connected and the original connector “bridged”.This is how CB014 is connected with the AVDI interface while the OBD connector is connected to the OBDII plug of the car. Once this is done, the Abrites Diagnostics for Tesla can be started:

The procedure for Model 3 does not apply to Model S/X vehicle.
The below photo shows the diagnostic port on Tesla Model S/X. The ZN071 cable(part of the ZN072 cable set) is used to the connect to the diagnostic port.

3.1. General Diagnostics
Once the software is started, the user will have the option to choose a brand and a model produced by this brand. After that the protocol of the vehicle will be automatically  detected and General Diagnostics screen will be displayed.
This is what the General Diagnostics screen looks like before the list of modules is generated:

3.1.1 Scanning for diagnostic trouble codes (DTCs)
When pressing the Scan button the user will see the electronic modules installed in the vehicle they are currently working with. The number of faults within each will also be  displayed. From there you can drill into each mod le and check it for fault codes. Reading the fault codes will give you a description of the fault. The details involved in each  code may vary in detail due to the specifics of the vehicle.

3.1.2 Clear faults
When selecting the “Clear faults” function once a module has been entered, all the diagnostic trouble codes will be deleted from the electronic modules available in the vehicle.
There may be fault codes that require additional user input (i.e component replacement and others) in order for the fault code to be cleared.
Please note that some fault codes may be indicative to special diagnostic procedures for the special functions of the Abrites Diagnostics for Tesla.
Tesla does not provide DTC descriptions when doing diagnostics but the fault code that can later be found in the Tesla fault codes database on their website.

3.1.3 Live values
In order to display the live values of a module within a vehicle you should select the “Live values” button followed by the module you would like to view the values for.

3.2 Service Functions
The Service functions menu in the software allow different service functions to be performed.
Some of them include entering the parking brake in service mode, IBST VIN learn and reset, test pedal offset, dim central, left or right mirrors, Head Lamp communication  test, HOMELINK communication test, window calibration on all doors, NFC amplitude reading, etc. Here are some of the recently added functions:

•  Front left and Rear right brake bleed (start bleed from here)
•  Front right and Rear left brake bleed
•  Thermal Coolant Air Purge
•  Thermal Fill Drain
•  Steering Column Calibration
• “12V Reset” – E-Fuse reset done trough the software instead of disconnecting all the batteries.

Special Functions

The Abrites Disgnostics For Tesla software offers special functions that allow different varieties of procedures that can be applied to either program keys, perform airbag reset or other adaptations.
4.1 Key Learning- adding a spare key
The key learning special function allows the addition of a spare key for Model S/X vehicles completely by OBD. To start the key learning procedure, you can follow the steps  described in screenshots below after starting the Tesla software:

1. Select the Model
2. Select the Key Learning menu and follow the instructions in the software

Note: Whenever doing the key learning, make sure to follow all the steps to make the proper connection as described in chapter 3 – “Using the Abrites diagnostics for Tesla”.

The software will open the next window which consists of 4-5 steps that are to be followed in order to program one or more spare keys:

1. Press the lock button on all keys you want to keep and verify that they are shown as “Active”

2. Move a key to be programmed to within 30cm of the center console LF coil (near the cup holders)

3. Press and hold the front and rear trunk buttons simultaneously for 5 seconds and then release them
   Important: Do not hold the buttons for more than 5 seconds!

4. Wait until the key is programmed – its status should change from “Programming” to “Active”
   Repeat steps 2-4 to program each new key or to retry programming if one of the keys does not change from “Programming” to “Active”.

4.2 Airbag Reset – clear crash data, read/write VIN
The TESLA Airbag Reset special function gives access to customers to perform various calibrations in the airbag module of all TESLA vehicles (Model S/X and Model 3).
It covers both Bosch and Delphi produced airbag modules completely by diagnostics.
Supported functions for Bosch airbag modules:

• Airbag exchange
•  read/update data in the module (modify EEPROM)
•  clear crash data
•  change VIN

Important: All functions for Delphi airbag are performed by diagnostics(ZN072 cable set for Tesla is required).
Supported functions for Delphi airbag modules:

• read EEPROM (on bench)
•  clear crash data (on bench)

In order to read the EEPROM of the Delphi airbag module you will need the following connection to the
Delphi airbag module through the CB100 cable of the AVDI:
B+(Delphi airbag) -> B+ (external power supply)
GND (Delphi airbag) -> GND (external power supply)
CAN H (Delphi airbag) -> pin 1 (CB100 Abrites OBDII cable)
CAN L (Delphi airbag) -> pin 9 (CB100 Abrites OBDII cable)

In order to clear the crash data you will need to bridge these two point on the PCB of the airbag module and clear the DTCs: Once you clear the DTCs , the crash data will be cleared and you can restore the PCB to its original form by removing the bridge and return the airbag module to the vehicle.
