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" position. 

1. CHECK KEY INTERLOCK CABLE 

   Check the key interlock cable for damage.

   OK or NG 

   OK : GO TO 2.

   NG : Repair or replace key interlock cable. Refer to "KEY INTERLOCK CABLE ".

2. CHECK SELECTOR LEVER POSITION 

   Check the selector lever position for damage. Refer to "CHECKING OF A/T POSITION "

   OK or NG 

   OK : GO TO 3.

   NG : Adjust A/T position. Refer to "ADJUSTMENT OF A/T POSITION ".

3. CHECK SHIFT LOCK SOLENOID AND PARK POSITION SWITCH 
   1. Connect A/T device harness connector.
   2. Turn ignition switch ON. (Do not start engine.)
   3. Selector lever is set in "P" position.
   4. Check operation.

      Check stop lamp switch after adjusting brake pedal - refer to " BRAKE PEDAL  "  .

   OK or NG 

   OK : GO TO 6.

   NG : Repair or replace damaged parts.

6. DETECT MALFUNCTIONING ITEM 

   Check the following items. If any items are damaged, repair or replace damaged parts.

   • Harness for short or open between ignition switch and stop lamp switch harness connector E210 terminal 3.
   • Harness for short or open between stop lamp switch harness connector E210 terminal 4 and A/T device harness connector M67 terminal 1.
   • 10 A fuse [No.12, located in the fuse block (J/B)].
   • Ignition switch, Refer to "POWER SUPPLY ROUTING CIRCUIT ".

   OK or NG 

   OK : INSPECTION END 

   NG : Repair or replace damaged parts.

7. CHECK GROUND CIRCUIT 
   1. Turn ignition switch OFF.
   2. Disconnect A/T device harness connector.
   3. Check continuity between A/T device harness connector M67 terminal 2 and ground.

      Continuity should exist. 

   OK or NG 

   OK : Replace shift lock solenoid and park position switch assembly.

   NG : Repair open circuit in harness or connectors.
