Diagnostic Procedure
DIAGNOSTIC PROCEDURE
| Step | Check | Yes | No |
|---|---|---|---|
1 CHECK HARNESS.
|
Is the resistance less than 1 Ω? | Go to step 2 . | Repair the harness and connector between electronic parking brake CM and parking brake switch connector. |
| 2 CHECK HARNESS. Measure the resistance of harness between parking brake switch connector and chassis ground. Connector & terminal (i163) No. 2 - Chassis ground: (i163) No. 1 - Chassis ground: (i163) No. 9 - Chassis ground: (i163) No. 3 - Chassis ground: |
Is the resistance 1 MΩ or more? | Go to step 3 . | Repair ground short of harness between electronic parking brake CM and parking brake switch connector. |
| 3 CHECK HARNESS. Measure the voltage between parking brake switch connector and chassis ground. Connector & terminal (i163) No. 2 (+) - Chassis ground (-): (i163) No. 1 (+) - Chassis ground (-): (i163) No. 9 (+) - Chassis ground (-): (i163) No. 3 (+) - Chassis ground (-): |
Is the voltage less than 1 V? | Go to step 4 . | Repair short to power supply of harness between electronic parking brake CM and parking brake switch connector. |
| 4 CHECK PARKING BRAKE SWITCH. Check the parking brake switch. < Refer to INSPECTION , Parking Brake Switch. > |
Is the parking brake switch normal? | Go to step 5 . | Replace the parking brake switch. < Refer to PARKING BRAKE SWITCH . > |
5 CHECK ELECTRONIC PARKING BRAKE CM.
|
Is the same DTC displayed? | Replace the electronic parking brake CM. < Refer to PARKING BRAKE ACTUATOR . > | Go to step 6 . |
| 6 CHECK OTHER DTC DETECTION. | Is any other DTC displayed? | Perform the diagnosis according to DTC. | It results from a temporary noise interference. |
