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 

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

   Check selector lever position for damage.

   OK or NG 

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

   Turn ignition switch to "OFF" 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: 0V 

   OK or NG 

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