INSPECTION PROCEDURES FOR TROUBLE SYMPTOM
Inspection procedure 1
When the ignition switch is at a position other than the
LOCK position, the selector lever can be moved from the
P to the R position even though the brake pedal is not
depressed.
Probable cause
The cause is probably a malfunction of the selector lever assembly lock cam or
of the shift lock cable unit.DMalfunction of lock cam
DMalfunction of shift lock cable unit
Check by referring to the probable causes.
Inspection procedure 2
When the ignition switch is at a position other than the
LOCK position, the selector lever cannot be moved from
the P to the R position even though the brake pedal is
being depressed.
Probable cause
The cause is probably a malfunction of the selector lever assembly, transmission
control cable, shift lock cable unit or the ignition key cylinder lock bar.DMalfunction of selector lever assembly
DMalfunction of transmission control cable
DMalfunction of shift lock cable unit
DMalfunction of lock bar
