Diagnosis Procedure

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

1. CHECK DTC WITH BCM
   
   

   Refer to DTC INDEX .

   Is the inspection result normal?

   YES 

   GO TO STEP 2. 

   NO 

   Repair or replace malfunctioning parts.

2. CHECK TRANSMISSION RANGE SWITCH INPUT SIGNAL
   
   
   1. Turn ignition switch OFF.
   2. Disconnect IPDM E/R harness connector.
   3. Turn ignition switch ON.
   4. Check voltage between IPDM E/R harness connector E119 terminal 37 and ground under following condition.

      IPDM E/R		Ground	Condition		Voltage (V)
      Connector	Terminal
      E119	37	Ground	CVT selector lever	P (Park) or N (Neutral)	Battery voltage
      				Other than above	0

   Is the inspection result normal?

   YES 

   Replace IPDM E/R. Refer to REMOVAL AND INSTALLATION .

   NO 

   GO TO STEP 3  .

3. CHECK TRANSMISSION RANGE SWITCH CIRCUIT FOR CONTINUITY
   
   
   1. Turn ignition switch OFF.
   2. Check continuity between IPDM E/R harness connector terminals 63 and 66.

      IPDM E/R			Condition		Continuity
      Connector	Terminals
      F24	63	66	Transmission range switch	P or N	Yes
      				Other	No

   Is the inspection result normal?

   YES 

   GO TO STEP 4. 

   NO 

   GO TO STEP 5  .

4. CHECK TRANSMISSION RANGE SWITCH CIRCUIT FOR SHORT
   
   

   Check continuity between IPDM E/R harness connector terminals 63, 66 and ground.

   IPDM E/R		Ground	Continuity
   Connector	Terminal
   F24	63	Ground	No
   	66

   Is the inspection result normal?

   YES 

   Replace the IPDM E/R. Refer to REMOVAL AND INSTALLATION .

   NO 

   Repair or replace harness.

5. CHECK TRANSMISSION RANGE SWITCH INPUT SIGNAL CIRCUIT
   
   
   1. Disconnect transmission range switch harness connector.
   2. Check continuity between transmission range switch and IPDM E/R harness connectors.

      Transmission range switch		IPDM E/R		Continuity
      Connector	Terminal	Connector	Terminal
      F29	7	F24	63	Yes
      	10		66

   3. Check continuity between transmission range switch harness connector and ground.

      Transmission range switch		Ground	Continuity
      Connector	Terminal
      F29	7	Ground	No
      	10

   Is the inspection result normal?

   YES 

   GO TO STEP 6  .

   NO 

   Repair harness or connector.

6. CHECK INTERMITTENT INCIDENT
   
   

   Refer to INTERMITTENT INCIDENT .

   Inspection End.
