VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1288

DTC Code DTC Name
C1288 Error in Matching of ECUs

DESCRIPTION

The skid control ECU (brake actuator assembly) stores this DTC when the previously learned values in the VSC system and engine information sent from the ECM are inconsistent, or when the learning has not completed after the skid control ECU (brake actuator assembly) is replaced with a new one.

DTC No. DTC Detection Condition Trouble Area
C1288 ECM does not match.

  • ECM

  • Skid control ECU (Brake actuator assembly)

CAUTION / NOTICE / HINT

Note

When replacing the skid control ECU (brake actuator assembly), perform system variant learning and acceleration sensor zero point calibration Click here.

  3. CHECK PART NUMBER (ECM)


    1. Check that the part number of the installed ECM is correct.

      OK
      ECM installed in the vehicle has the correct part number.

    REPLACE ECM Click here

    OK

  4. PERFORM SYSTEM VARIANT LEARNING


    1. Perform the system variant learning Click here.

      Tech Tips


      • System variant learning is automatically performed immediately after Test Mode is entered.

      • If learning has not yet been performed, the slip indicator light will remain on and DTC C1288 will be stored.

      • If system variant learning is not successful, the warning lights will not blink in the Test Mode pattern and DTC C1288 will not be cleared.
