DTC Table
NOTE:
- DTC C1122 is indicated when engine switch is pressed to change the ignition mode to "ON" and engine is stopping, but it means there is nothing abnormal if indication changes to a normal when engine is started.
- *D/C (Driving Cycle) is a duration from an engine start-up to the following engine shutoff.
- 1 D/C: When the malfunction is detected in 1st driving cycle, "P/S" warning light is turned ON.
