Tip:

*1: If the engine switch is turned off after idling for 60 seconds, this DTC may be stored when the engine is started again.

Note:

  • Before starting troubleshooting, be sure to clear the DTCs stored due to the reason described in the HINT above. Then, check for DTCs and troubleshoot according to the output DTCs.

      1. Check if "01-DC" is output for the other components.

      2. If "01-DC" is output for any other components, check if the same physical address is displayed.

        Table 1. Result
        Result Proceed to
        "01-DC" is output and the same physical address is displayed A
        "01-DC" is not output or the same physical address is not displayed B
        Tip:

        For the list of the components shown by sub-codes, refer to the table in step 2.
