Diagnostic Procedure

SYMPTOM: 

• 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  .

1. CHECK SELECTOR LEVER POSITION 

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

   OK or NG 

   OK: GO TO 2.

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

2. CHECK POWER SOURCE 
   1. Turn ignition switch OFF.
   2. Disconnect shift lock relay.
   3. Check voltage between shift lock relay E35 terminal 2 and ground.

      Voltage 

      Brake pedal depressed: Battery voltage 

      Brake pedal released: 0 V

   OK or NG 

   OK: GO TO  4.

   NG: GO TO 3.

3. DETECT MALFUNCTIONING ITEM 

   Check the following.

   • Harness for short or open between battery and stop lamp switch harness connector E124 terminal 1
   • Harness for short or open between stop lamp switch harness connector E124 terminal 2 and shift lock relay E35 terminal 2
   • 10A fuse [No.20, located in the fuse block (J/B)]
   • Stop lamp switch
     • Check continuity between stop lamp switch harness connector E124 terminals 1 and 2

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

   • ICC brake hold relay. Refer to ICC BRAKE HOLD RELAY . (With ICC only)
   • Harness for short or open between battery and ICC brake hold relay E80 terminal 3. Refer to C1A13 STOP LAMP RLY FIX . (With ICC only)
   • Harness for short or open between ICC brake hold relay E80 terminal 5 and shift lock relay E35 terminal 2. (With ICC only)
   • Harness for short or open between ICC sensor integrated unit harness connector E61 terminal 2 and ICC brake hold relay E80 terminal 2. Refer to C1A13 STOP LAMP RLY FIX . (With ICC only)
   • Harness for short or open between ICC brake hold relay E80 terminal 1 and ground. Refer to C1A13 STOP LAMP RLY FIX . (With ICC only)

   OK or NG 

   OK: GO TO  4.

   NG: Repair or replace damaged parts.

4. CHECK GROUND CIRCUIT 
   1. Turn ignition switch OFF.
   2. Disconnect shift lock relay.
   3. Check continuity between shift lock relay E35 terminal 1 and ground.
      CAUTION: Connect test probe (BLACK) to shift lock relay, and test probe (RED) to ground.

      Continuity should exist  .

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

   OK or NG 

   OK: GO TO  5.

   NG: Repair open circuit or short to ground or short to power in harness or connectors.

5. CHECK INPUT SIGNAL A/T DEVICE 
   1. Turn ignition switch OFF.
   2. Disconnect A/T device harness connector.
   3. Turn ignition switch ON.
   4. Check voltage between A/T device harness connector M133 terminal 7 and ground.

      Voltage 

      Brake pedal depressed: Battery voltage 

      Brake pedal released: 0 V
