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. It can be removed when selector lever is set to any position except "P". 

1. CHECK KEY INTERLOCK CABLE 

   Check key interlock cable for damage.

   OK or NG 

   • OK: GO TO  2.
   • NG: Repair key interlock cable. Refer to COMPONENTS .
2. CHECK SELECTOR LEVER POSITION 

   Check selector lever position for damage.

   OK or NG 

   • OK: GO TO  3.
   • NG: Check selector lever. Refer to CONTROL CABLE ADJUSTMENT .
3. CHECK POWER SOURCE 

   Turn ignition switch to "ON" position.

   (Do not start engine.)

   • Check voltage between A/T device harness connector M44 terminal 7 (G) and ground.
     • Voltage: 
     • Brake pedal depressed: Battery voltage 
     • Brake pedal released: 0 V 

   OK or NG 

   • OK: GO TO  5.
   • NG: GO TO  4.

4. DETECT MALFUNCTIONING ITEM 

   Check the following items.

   1. Harness for open or short between fuse block (J/B) connector M1 terminal 12K and stop lamp switch harness connector M26 terminal 3.
   2. Harness for open or short stop lamp switch harness connector M26 terminal 4 and A/T device harness connector M44 terminal 7 (G).
   3. 10A fuse [10, located in the fuse block (J/B)].
   4. Check continuity between stop lamp switch harness connector M26 terminals 3 (G) and 4 (G).
      CONTINUITY CONDITION
      
      

      Condition	Continuity
      When brake pedal is depressed	Yes
      When brake pedal is released	No

      Check stop lamp switch after adjusting brake pedal; refer to STOP LAMP SWITCH AND ASCD CANCEL SWITCH CLEARANCE .

   OK or NG 

   • OK: GO TO  5.
   • NG: Repair or replace damaged parts.

5. CHECK GROUND CIRCUIT 
   1. Turn ignition switch to "OFF" position.
   2. Disconnect A/T device harness connector.
   3. Check continuity between A/T device harness M44 terminal 6 (B) and ground.
      • Continuity should exist 

      Continuity should exist.

      If OK, check harness for short to power.

   OK or NG 

   • OK: GO TO  6.
   • NG: Repair open circuit in harness.

6. CHECK PARK POSITION SWITCH 

   Check continuity between A/T device harness connector M44 terminals 6 (B) and 7 (G).

   CONTINUITY CONDITION
   
   

   Selector lever position	Continuity
   "P" position	Yes
   Other position	No

   OK or NG 

   • OK: GO TO  7.
   • NG: Replace park position switch.

   OK or NG 

   • OK: GO TO  8.
   • NG: Replace shift lock solenoid.
8. CHECK SHIFT LOCK OPERATION 
   1. Reconnect shift lock harness connector.
   2. Turn ignition switch from "OFF" to "ON" position. (Do not start engine.)
   3. Recheck shift lock operation.

   OK or NG 

   • OK: INSPECTION END
   • NG: GO TO  9
9. CHECK A/T DEVICE INSPECTION 
   1. Perform A/T device input/output signal inspection test.
   2. If NG, recheck harness connector connection.

   OK or NG 

   • OK: INSPECTION END
   • NG: Repair or replace damaged parts.
