Diagnostic Procedure

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: 

• Ignition key cannot be removed when selector lever is set to "P" position. 
• Ignition key can be removed when selector lever is set to any position except "P". 

1. CHECK KEY INTERLOCK CABLE 

   Check the key interlock cable for damage.

   OK or NG

   • OK: GO TO 2.
   • NG: Repair key interlock cable. Refer to "KEY INTERLOCK CABLE ".
2. CHECK SELECTOR LEVER POSITION 

   Check the selector lever position for damage.

   OK or NG

   • OK: GO TO 3.
   • NG: Check selector lever. Refer to "CONTROL CABLE ADJUSTMENT ".
3. CHECK SHIFT LOCK SOLENOID AND PARK POSITION SWITCH 
   1. Connect A/T device harness connector.
   2. Turn ignition switch "ON".
   3. Selector lever is set in "P" position.
   4. Check operation sound.
