    1. Clear the DTC(s) Click here.

    2. Start the engine.

    3. Check if the same DTC(s) is output Click here.

      Result
      Result Proceed to
      DTC C1225 is not output A
      DTC C1225 is output (for LHD) B
      DTC C1225 is output (for RHD) C

      Tech Tips

      If any DTCs are output while jiggling a connector or wire harness of the skid control ECU (brake actuator assembly), inspect and repair the connector or wire harness. The DTCs were possibly output due to a bad connection of the connector terminal.
