- *1: If any INF codes are output for this DTC, refer to the corresponding diagnostic procedure.
- P0A94-442 may be stored due to a malfunction which also causes DTCs in the preceding table to be stored. In this case, first troubleshoot the output DTCs in the preceding table. Then, perform a test to attempt to reproduce the problems, and check that no DTCs are output.
- Turn the power switch off.
