Diagnostic Procedure

SYMPTOM 1: 

• Selector lever cannot be moved from "P" position with ignition switch in ON position and brake pedal depressed. 
• Selector lever can be moved from "P" position with ignition key in ON position and brake pedal released. 
• Selector lever can be moved from "P" position when ignition switch 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" position. 

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 "REMOVAL AND INSTALLATION ".

2. CHECK A/T POSITION 

   Check A/T position. Refer to "CHECKING OF A/T POSITION ".

   OK or NG 

   OK >> GO TO 3.

   NG >> Adjust control cable. Refer to "ADJUSTMENT OF A/T POSITION ".

3. CHECK SHIFT LOCK SOLENOID AND PARK POSITION SWITCH 
   1. Turn ignition switch ON. (Do not start engine.)
   2. Selector lever is set in "P" position.
   3. Check operation sound.
      BRAKE PEDAL CONDITION
      
      

      Condition	Brake pedal	Operation sound
      When ignition switch is turned to ON position and selector lever is set in "P" position.	Depressed	Yes
