DTC C136F-00: Non-learning of the Braking System information. [11/2021 - 10/2023]: 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.
NOTE:
DTC C136F-00 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.
