Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

1. CHECK A/T SHIFT SELECTOR (PARK POSITION SWITCH) INPUT SIGNAL
   1. Turn ignition switch OFF.
   2. While pressing the ignition knob switch, check voltage between Intelligent Key unit harness connector M164 terminal 39 and ground.

   Connector	Terminals		Condition	Voltage (V) (Approx.)
   	(+)	(-)
   M164	39	Ground	Selector lever is in "P" position	Battery voltage
   			Other than above	0

   Is the inspection result normal? 

   YES: Replace Intelligent Key unit. Refer to "REMOVAL AND INSTALLATION ".

   NO: GO TO 2

2. CHECK A/T SHIFT SELECTOR (PARK POSITION SWITCH) POWER SUPPLY CIRCUIT
   1. Disconnect A/T shift selector (park position switch) connector.
   2. While pressing the ignition knob switch, check voltage between A/T shift selector (park position switch) harness connector M158 terminal 4 and ground.

      4 - Ground: Battery voltage  .

      Is the inspection result normal? 

      YES: GO TO 3

      NO: Repair or replace harness or ignition knob switch.

3. CHECK A/T SHIFT SELECTOR (PARK POSITION SWITCH) GROUND SUPPLY CIRCUIT

   Check continuity between A/T shift selector (park position switch) terminal 2 and ground.

   2 - Ground: Continuity should exist  .

   Is the inspection result normal? 

   YES: GO TO 4

   NO: Repair or replace harness.

4. CHECK A/T SHIFT SELECTOR (PARK POSITION SWITCH)

   Check continuity between A/T shift selector (park position switch) terminals 2 and 4.

   Component	Terminals		Condition	Continuity
   A/T shift selector (park position switch)	2	4	Selector lever is in "P" position	Yes
   			Other than above	No

   Is the inspection result normal? 

   YES: GO TO 5

   NO: Replace A/T shift selector (park position switch).
