DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

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

2. Turn 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. Check DTC in “Self-Diagnostic Result” mode of “BCM” using CONSULT.
Is DTC detected?

YES

>> Go to 

SEC-107, "Diagnosis Procedure"

.

NO

>> Inspection End.

Diagnosis Procedure

INFOID:0000000009176024

Regarding Wiring Diagram information, refer to 

SEC-27, "Wiring Diagram"

.

1.

CHECK CVT SHIFT SELECTOR SWITCH FUNCTION

B2601 SHIFT POSITION

2.

CHECK CVT SHIFT SELECTOR CIRCUIT (BCM)

1. Disconnect BCM connector and IPDM E/R connector.

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

connector.

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

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace harness.

3.

CONNECTOR INSPECTION

1. Disconnect BCM.

2. Check connectors and terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace as necessary.

4.

REPLACE BCM

1. Replace BCM. Refer to 

BCS-80, "Removal and Installation"

.

2. Perform initialization of BCM and registration of all Intelligent Keys using CONSULT. Refer to the CON-

SULT Immobilizer mode and follow the on-screen instructions.

>> Inspection End.

5.

CHECK CVT SHIFT SELECTOR CIRCUIT (IPDM E/R)

Check continuity between CVT shift selector (park position switch) harness connector and IPDM E/R harness

connector.

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Repair or replace harness.

6.

CONNECTOR INSPECTION

1. Disconnect IPDM E/R.

2. Check connectors and terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?

YES

>> GO TO 7.

NO

>> Repair or replace as necessary.

7.

REPLACE IPDM E/R

1. Replace IPDM E/R. Refer to 

PCS-32, "Removal and Installation"

.

>> Inspection End.
