PERFORM DTC CONFIRMATION PROCEDURE

CONSULT

1. Shift the selector lever to the P (Park) position.

2. Ignition switch ON and wait 2 seconds or more.

3. Shift the selector lever to any position other than P (Park) and wait 2 seconds or more.

4. Select “Self Diagnostic Result” mode of “BCM”.

5. Check DTC.

Is DTC detected?

Refer to Diagnosis Procedure.

Inspection End.

CHECK CVT SHIFT SELECTOR FUNCTION

CONSULT

1. Ignition switch ON.

2. Select “DETE/CANCL SW” and “DETE SW - IPDM” in “Data Monitor” mode of “BCM(INTELLIGENT KEY)”.

3. Check “DETE/CANCL SW” and “DETE SW - IPDM” indication under the following conditions:

   Monitor item	Condition		Indication
   DETE/CANCL SW	CVT Shift selector	In any position other than P (Park)	ON
   		P (Park)	OFF
   DETE SW - IPDM	CVT Shift selector	In any position other than P (Park)	ON
   		P (Park)	OFF

Is the inspection result normal?

Refer to Intermittent Incident.

If “DETE/CANCL SW” function is incorrect. GO TO 2.

If “DETE SW - IPDM” function is incorrect. GO TO 5.

CHECK CVT SHIFT SELECTOR CIRCUIT (BCM)

1. Disconnect CVT shift selector (detent switch) connector and IPDM E/R connector.

2. Check continuity between CVT shift selector (detent switch) harness connector and BCM harness connector.

   CVT shift selector (detent switch)		BCM		Continuity
   Connector	Terminal	Connector	Terminal
   M78	6	M18	20	Yes

3. Check continuity between CVT shift selector (detent switch) harness connector and ground.

   CVT shift selector (detent switch)		Ground	Continuity
   Connector	Terminal
   M78	6		No

Is the inspection result normal?

GO TO 3.

Repair or replace harness.

CONNECTOR INSPECTION

1. Disconnect BCM connector.

2. Check connectors and terminals for deformation, disconnection, looseness or damage.

Is the inspection result normal?

GO TO 4.

Repair or replace as necessary.

REPLACE BCM

1. Replace BCM. Refer to Removal and Installation.

2. Perform initialization of BCM and registration of all Intelligent Keys. Refer to Work Procedure.

Inspection End.

CHECK CVT SHIFT SELECTOR CIRCUIT (IPDM E/R)

1. Disconnect BCM connector M18, IPDM E/R connector and CVT shift selector (detent switch) connector.

2. Check continuity between CVT shift selector (detent switch) harness connector and IPDM E/R harness connector.

   CVT shift selector (detent switch)		IPDM E/R		Continuity
   Connector	Terminal	Connector	Terminal
   M78	6	E119	31	Yes

3. Check continuity between CVT shift selector (detent switch) harness connector and ground.

   CVT shift selector (detent switch)		—	Continuity
   Connector	Terminal
   M78	6	Ground	No

Is the inspection result normal?

GO TO 6.

Repair or replace harness.

CONNECTOR INSPECTION

1. Disconnect IPDM E/R connector.

2. Check connectors and terminals for deformation, disconnection, looseness or damage.

Is the inspection result normal?

GO TO 7.

Repair or replace as necessary.

REPLACE IPDM E/R

Replace IPDM E/R. Refer to Removal and Installation.

Inspection End.

CHECK CVT SHIFT SELECTOR (DETENT SWITCH)

1. Ignition switch OFF.

2. Disconnect CVT shift selector (detent switch) connector.

3. Check continuity between CVT shift selector (detent switch) terminals.

   CVT shift selector (detent switch)		Condition		Continuity
   Terminal
   5	6	Selector lever	P (Park) position	No
   			Other than above	Yes

Is the inspection result normal?

Inspection End.

Replace CVT shift selector. Refer to Removal and Installation.
