All of the Toyota/Lexus models that are covered by the TN011, TN012 and TN013 licenses share the same Smart System pin out when connecting to the internal CAN BUS where pin 1 is the CAN H and PIN 2 is CAN L.

This is what the connector looks like and what pins to connect to when working with CB012:

CB031 – Еxtension Cable for Direct Connecting to Toyota/Lexus Smart System with B9/BA Key – will let you make the connection to vehicles Toyota/Lexus equipped with Smart System with B9/BA Key. The connection to the smart system of the vehicle much easier, without the need to search for the CAN wires and puncture them. It helps in All Keys lost situation, when you need to read the Smart System Module.

In order to use CB031:

Disconnect the smart system connector
Connect CB031 to the smart system and to the wire (connector) from the vehicle – it works as a bypass
Connect dedicated slots to the CB012 CAN connectors (Red and Blue)

Deleting keys
Toyota Online software gives you the option to delete lost keys from the memory of the vehicle. In order to complete the task, you have to open the “Key Learning” special function and select “Delete Keys” menu. You then need to follow the on-screen instructions.

Important: Make sure you have a working key for the vehicle so that the procedure can be completed with success – the car will remain with the working key learned to the vehicle, and the rest of the keys deleted.

Airbag

The latest update of the Toyota Online software introduces the option to read/write Dflash and clear Crash Data of Airbag modules 2020+. This option is access from the main screen, on the left hand side you will see a button “Airbag”, which will open the menu and the functionality. The software is intuitive, from the buttons you are able to read the Dflash, clear the crash data, and then write the file back to the unit.

Mileage Calibration

The Toyota/Lexus Online software provides the mileage calibration option for instrument clusters using S6J3 unlocked MCUs. Under the “Dash Calibration” menu there are 4 options:

“Read” – to read dashboard and display the current odometer value (During this procedure a backup file is created)
“Write” – to write the new value of the odometer. Write procedure will also create a backup file.
“Restore” – to restore the original file to the unit, by selecting a file from a drop-down menu
“Wiring diagrams” – it will show the available dashboards and corresponding wiring connection diagram.

Required Hardware:

AVDI
ZN030 (ABPROG)
ZN078 (V850ES Adapter for ABPROG

Connection:
The wiring diagram is provided within the Toyota/Lexus Online Software > Dash Calibration > Wiring Diagrams

Procedure steps and sequence:

Solder the wires of the ZN078 adapter on the points provided in the wiring diagram menu.
Connect to the ZN078 Adapter the ABPROG and then connect the ABPROG to the AVDI interface
Connect the AVDI interface to the PC’s USB Port
Start the Toyota/Lexus Online software, and select the vehicle Select “Dash Calibration” special function

Next, you can proceed to reading the unit, which will display the current mileage value. You can then set the new value and press “write,” which will set the new value into the unit.

You can always restore the unit, backup is automatically created, and you can select the file you need from a drop down menu.

ID Code Box Reset

ID Code box reset is necessary if the smart system, the ECU, or the ESL is replaced. The replacement module should be paired with the ID Code Box. For this synchronization, a “virgin” or new ID Code Box is needed.
ID-Code Box 2021+ reset and adaptation functionality helps in immobilizer module replacement situations in all Toyota and Lexus models, produced until 2024.
Legacy functionality of TN009 is also included, and it works for resetting ID Code Box units of vehicle up to 2020, with or without an ELS.

A working key for the vehicle is needed!
In case of a Smart System replacement, you will most probably have no working key for the replacement smart system. At this point you will have to first execute a key learning procedure, and continue with the ID Code box reset once a working key is present.

NOTE: Without the ID Code Box reset functionality, replacing any immobilizer-related module in Toyota vehicles would require swapping the entire immobilizer system – the Smart System, ID Code Box, Engine Control Unit (ECU), and ESL (if present). This would mean extensive disassembly and significant costs for both labor and replacement parts. However, with the ID Code Box reset functionality, you can simply reset the ID Code Box and synchronize a used module. This allows for seamless integration without the need to replace additional system components, saving time and reducing overall costs.

When a virgin ID-code box is installed in the vehicle, synchronization with the ECU and Smart system is required!

Supported vehicles:

All Toyota and Lexus models up to 2024
N.B. In case the ID-Code-Box reset function is not possible for the module you are working with, please contact us at support@abrites.com

Connections
In order to perform ID-Code-Box reset procedure, internal LIN-BUS connections is needed. For the purpose use the CB012 (mandatory) and CB031 (recommended) cables for this purpose.

CB012 needs to be connected between the AVDI and the CB106, the red connector of the CB012 is connected to the green connector of the CB031.
Disconnect the Smart System (SMT)
CB031 is connected to the wiring installation connector that goes normally into the smart system.. (If CB031 is not available, please connect the red cable of CB012 with the use of the needle pinch to the wire that goes to PIN 8 (LIN) of the Smart System Module (SMT),

N.B. Make sure the SMT is disconnected and do not connect the other side of the CB031 to the SMT

ID Code Box Reset Procedure
Once the connections are done, the procedure is very simple and fast.

Open the Toyota Online software
Select “ID Code Box” special function
Press “Reset”

Smart System Synchronization

ID-Code-Box adaptation (synchronization) procedure in vehicle (new or virgin second-hand module) to the Smart System via OBDII is needed after the ID code box reset procedure.

Required connections:
Procedure is executed via OBDII
Connect AVDI to CB106 and CB106 to the OBDII port of the vehicle.

Procedure
Once the connections are done, the procedure is very simple and fast.

Open the Toyota Online software
Select “ID Code Box” special function (at this point you will need IGN ON with a working key)
Press “Sync SMT”

Once complete, you will have the Smart System and ID Code Box synchronized. ECU still needs to be synchronized at this point.

ECU Synchronization

ID-Code-Box adaptation (synchronization) with the Engine Control Unit via OBDII is needed after if you are exchanging the ID Code Box or the Engine Control Unit (ECU/HV)

If the synchronization of the ECU is lost you will get the following DTC: “B279986” which will also point you to the necessity of executing the ECU Sync procedure.

Requirements:
External power supply is strongly recommended, as the procedure takes about 40 min.
Procedure is executed via OBDII
Connect AVDI to CB106 and CB106 to the OBDII port of the vehicle.

Procedure
Once the connections are done, the procedure is very simple and it takes about 40 min.

Open the Toyota Online software
Select “ID Code Box” special function
Press “Sync Engine”
N.B. “do not touch anything in the vehicle during the procedure”

At this point you should have the vehicle fully functional.
