A/T Shift Lock System

Description





- The mechanical key interlock mechanism also operates as a shift lock:
With the key switch turned to "ON", the selector lever cannot be shifted from "P" (parking) to any other position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from "P" to any other position.
The key cannot be removed unless the selector lever is placed in "P".
- The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock solenoid and by the operation of the rotator and slider located inside the key cylinder, respectively.

SYMPTOM 1:
- Selector lever cannot be moved from "P" position with key in "ON" position and brake pedal applied.
- Selector lever can be moved from "P" position with key in "ON" position and brake pedal released.
- Selector lever can be moved from "P" position when key is removed from key cylinder.

SYMPTOM 2:

Component Check
SHIFT LOCK SOLENOID





- Check operation by applying battery voltage between shift lock solenoid harness connector terminal 2 and A/T device harness connector terminal 5.

PARK POSITION SWITCH








- Check continuity between park position switch harness connector terminal 2 and A/T device harness connector terminal 6.

ASCD BRAKE SWITCH








- Check continuity between ASCD brake switch harness connector terminals 1 and 2.
Check ASCD brake switch after adjusting brake pedal.
