DTC Table

Precautions: Precautions for Diagnosing Trouble · Precautions for Steering · General safety (00)

NOTE:
•If you do not perform P/S System Check before starting the DTC diagnosis, the diagnosis will show a false result.
Perform P/S System Check before starting the diagnosis.
•*D/C (Driving Cycle) is a duration from engine start to the following engine shutoff.
—1 D/C: When a malfunction is detected in 1st driving cycle, P/S warning light is turned ON.
•*1: Whether P/S warning light lights up or not depends on DTC detecting condition.
