TROUBLE SYMPTOM CHART

SYMPTOM PROCEDURES

INSPECTION PROCEDURE 1: When the ignition key is at a position other than the LOCK (OFF) position, the selector lever can be moved from the P to the R position even though the brake pedal is not depressed.

INSPECTION PROCEDURE 2: When the ignition key is at a position other than the LOCK (OFF) position, the selector lever cannot be moved from the P to the R position even though the brake pedal is being depressed.

INSPECTION PROCEDURE 3: The ignition key is at the LOCK (OFF) position, but the selector lever can be moved from the P to the R position when the brake pedal is depressed.

INSPECTION PROCEDURE 4: The selector lever cannot be easily moved from the P to the R position.

INSPECTION PROCEDURE 5: The selector lever cannot be moved from the R to the P position.

INSPECTION PROCEDURE 6: The ignition key cannot be turned to the LOCK (OFF) position when the selector lever is at the P position.

INSPECTION PROCEDURE 7: The ignition key can be turned to the LOCK (OFF) position when the selector lever is at a position other than the P position.
