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.

6. DETECT MALFUNCTIONING ITEM 

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

   • 10A fuse [No.1, located in the fuse block (J/B)]
   • Harness for short or open between ignition switch and stop lamp switch harness connector E38 terminal 3.
   • Harness for short or open between stop lamp switch harness connector E38 terminal 4 and diode-4 harness connector E149 terminal 2.
   • Harness for short or open between diode-4 harness connector E149 terminal 1 and A/T device harness connector M34 terminal 5.
   • Diode-4
   • Ignition switch (Refer to "POWER SUPPLY ROUTING CIRCUIT ".)

   OK or NG 

   OK: GO TO 7.

   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 M34 terminal 6 and ground.

      Continuity should exist. 

   4. Connect A/T device harness connector.
