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 key interlock cable for damage.

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

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

   OK or NG 

   1. OK: GO TO  3.
   2. NG: Check selector lever. Refer to ADJUSTMENT OF A/T POSITION .
3. CHECK POWER SOURCE 
   1. Turn ignition switch "ON". (Do not start engine.)
   2. Check voltage between A/T device harness connector terminal 2 and ground.
      1. Voltage: Battery voltage 

   OK or NG 

   1. OK: GO TO  5.
   2. NG: GO TO  4.

4. DETECT MALFUNCTIONING ITEM 

   Check the following.

   1. Harness for short or open between ignition switch and A/T device harness connector terminal 2.
   2. 10A fuse. [No.12, located in the fuse block (J/B)]
   3. Ignition switch. Refer to POWER SUPPLY ROUTING CIRCUIT .

   OK or NG 

   1. OK: GO TO  5.
   2. NG: Repair or replace damaged parts.
5. CHECK INPUT SIGNAL A/T DEVICE 
   1. Turn ignition switch "OFF".
   2. Disconnect A/T device harness connector.
   • Check voltage between A/T device harness connector terminal 4 and ground.
     1. Voltage: 
     2. Depressed brake pedal 
        1. Battery voltage 
     3. Released brake pedal 
        1. Approx. 0 V 

   OK or NG 

   1. OK: GO TO  7.
   2. NG: GO TO  6.

6. DETECT MALFUNCTIONING ITEM 

   Check the following.

   1. Harness for short or open between battery and stop lamp switch harness connector terminal 3.
   2. Harness for short or open between stop lamp switch harness connector terminal 4 and A/T device harness connector terminal 4.
   3. 10A fuse. [No.20, located in the fuse block (J/B)]
   4. Stop lamp switch.
      • Check continuity between stop lamp switch harness connector terminals 3 and 4.

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

   OK or NG 

   1. OK: GO TO  7.
   2. 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 terminal 1 and ground.
      1. Continuity should exist. 

      If OK, check harness for short to ground and short to power.

   OK or NG 

   1. OK: GO TO  8.
   2. NG: Repair open circuit or short to ground or short to power in harness or connectors.
