Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: ELECTRONICALLY CONTROLLED BRAKE SYSTEM (w/o Vacuum Brake Booster): C136F00; Non-learning of the Braking System information.; 2022 - 2024 MY RAV4 RAV4 HV [12/2021 -        ]

DTC

C136F00

Non-learning of the Braking System information.

DESCRIPTION

The No. 1 skid control ECU (brake booster with master cylinder assembly) stores identification information sent from other ECUs when the vehicle is shipped from the factory and changes the control constant for each system (ABS, VSC, TRAC, etc.) based on the identification information.

NOTICE:

DTC C136F00 is output when an incorrect ECU is installed. If initialization is performed and learning occurs with an incorrect ECU installed, operations and functions will differ from those stored when the vehicle was shipped from the factory. Therefore, make sure that learning occurs properly.
