P1211 TCS Control Unit

Description

The malfunction information related to TCS is transferred through the CAN communication line from "ABS actuator and electric unit (control unit)" to ECM.

Be sure to erase the malfunction information such as DTC not only for "ABS actuator and electric unit (control unit)" but also for ECM after TCS related repair.

On Board Diagnosis Logic

Freeze frame data is not stored in the ECM for this self-diagnosis. The MIL will not illuminate for this self-diagnosis.
