NOTE:

  

DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION PROCEDURE

  1. Turn ignition switch ON under the following conditions, and wait for at least 2 seconds.
    • CVT selector lever is in the P position.
    • Do not depress the brake pedal.
  1. Check "Self diagnostic result" with CONSULT-III.
  2. Turn ignition switch ON under the following conditions, and wait for at least 2 seconds.
    • CVT selector lever is in other than P position.
    • Do not depress the brake pedal.
  1. Check "Self diagnostic result" with CONSULT-III. Is DTC detected?

YES >> Refer to Diagnosis Procedure.
NO >> Inspection End.

Diagnosis Procedure
1.CHECK CVT DEVICE POWER SUPPLY

  1. Turn ignition switch to ACC.
  2. Disconnect CVT device (park position switch) harness connector.

  

  1. Check voltage between CVT device (park position switch) harness connector and ground.

  

Is the Inspection result normal?
YES >> GO TO 3
NO >> GO TO 2
2.CHECK CVT DEVICE POWER SUPPLY CIRCUIT

  1. Disconnect BCM harness connector.

  

  1. Check continuity between BCM harness connector M19 (A) terminal 84 and CVT device (park position switch) harness connector M23 (B) terminal 8.

  

  1. Check continuity between BCM harness connector M19 (A) terminal 84 and ground.

  

Is the Inspection result normal?
YES >> Replace BCM. Refer to See: Body and Frame\Body Control Systems\Body Control Module\Service and Repair.
NO >> Repair harness or connector.
3.CHECK CVT DEVICE CIRCUIT (BCM)

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

  

  1. Check continuity between BCM harness connector M19 (A) terminal 87 and CVT device (park position switch) harness connector M23 (B) terminal 9.

  

  1. Check continuity between BCM harness connector M19 (A) terminal 87 and ground.

  

Is the Inspection result normal?
YES >> GO TO 4
NO >> Repair harness or connector.
4.CHECK CVT DEVICE CIRCUIT (IPDM E/R)

  1. Disconnect BCM harness connector.

  

  1. Check continuity between CVT device (park position switch) harness connector M23 (A) terminal 9 and IPDM E/R harness connector E17 (B) terminal 43.

  

  1. Check continuity between CVT device (park position switch) harness connector M23 (A) terminal 9 and ground.

  

Is the Inspection result normal?
YES >> GO TO 5
NO >> Repair harness or connector.
5.CHECK CVT DEVICE
Refer to Component Inspection.
Is the Inspection result normal?
YES >> GO TO 6
NO >> Replace CVT device. Refer to See: Transmission and Drivetrain\Continuously Variable Transmission/Transaxle\Shifter CVT\Service and Repair\CVT RE0F10A\Removal And Installation.
6.CHECK INTERMITTENT INCIDENT
Refer to See: Testing and Inspection\Initial Inspection and Diagnostic Overview\Service Information For Electrical Incident\Intermittent Incident.
>> Inspection End.

Component Inspection
1.CHECK CVT DEVICE (PARK POSITION SWITCH)

  1. Turn ignition switch OFF.
  2. Disconnect CVT device (park position switch) harness connector.

  

  1. Check continuity between CVT device (park position switch) terminals as follows.

  

Is the Inspection result normal?
YES >> Inspection End.
NO >> Replace CVT device. Refer to See: Transmission and Drivetrain\Continuously Variable Transmission/Transaxle\Shifter CVT\Service and Repair\CVT RE0F10A\Removal And Installation.
