ON-VEHICLE INSPECTION

PROCEDURE

1. CHECK SHIFT LOCK OPERATION

(a) Move the shift lever to P.

(b) Turn the ignition switch off.

(c) Check that the shift lever cannot be moved from P.

(d) Turn the ignition switch to ON, depress the brake pedal and check that the shift lever can be moved to other positions.

If the operation cannot be performed as specified, inspect the shift lever assembly and shift lock control unit.

2. CHECK SHIFT LOCK RELEASE BUTTON OPERATION

(a) When operating the shift lever with the shift lock release button pressed, check that the lever can be moved to any position.

If the operation cannot be performed as specified, check the shift lever assembly.

3. CHECK KEY INTERLOCK OPERATION

(a) Turn the ignition switch to ON.

(b) Depress the brake pedal and move the shift lever to any position other than P.

(c) Check that the ignition switch cannot be turned off.

(d) Move the shift lever to P, turn the ignition switch off and check that the key can be removed.

If the results are not as specified, inspect the shift lock control ECU.
