Diagnostic Procedure

DTC C0039:07, C003A:07, C003A:29, C003A:2F, C003A:37 OR C003A:64 (DSC HU/CM) DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	VERIFY THAT THERE IS NO ABS WHEEL-SPEED SENSOR OUTPUT MALFUNCTION Select the following PIDs. (See PID/DATA MONITOR INSPECTION .) (See PID/DATA MONITOR TABLE [DSC HU/CM] .) WSPD_SEN_L/F WSPD_SEN_L/R WSPD_SEN_R/F WSPD_SEN_R/R Drive the vehicle. Verify that the vehicle speeds detected by the four ABS wheel-speed sensors are approximately the same. Are the vehicle speeds approximately the same?	Yes	Go to Step 4.
1		No	Go to the next step.
2	INSPECT ABS WHEEL-SPEED SENSOR (RR) CONNECTOR FOR MALFUNCTION Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION .) Are the connector and terminal normal?	Yes	Go to the next step.
2		No	Repair or replace the malfunctioning location and perform the repair completion verification.
3	INSPECT DSC HU/CM CONNECTOR FOR MALFUNCTION Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION .) Are the connector and terminal normal?	Yes	Go to the next step.
3		No	Repair or replace the malfunctioning location and perform the repair completion verification.
4	INSPECT IF MALFUNCTION OCCURRED DUE TO IMPROPER SENSOR CLEARANCE Inspect the clearance between the ABS wheel-speed sensor and the ABS sensor rotor. (See REAR ABS WHEEL-SPEED SENSOR INSPECTION [2WD] .) (See REAR ABS WHEEL-SPEED SENSOR INSPECTION [AWD] .) Is the clearance normal?	Yes	Go to the next step.
4		No	Replace the ABS wheel-speed sensor (RR) and perform the repair completion verification. (See REAR ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION .)
5	VISUALLY INSPECT ABS SENSOR ROTOR FOR FOREIGN MATERIAL ADHERING OR IMPROPER INSTALLATION Visually inspect for ABS sensor rotor. (See WHEEL HUB COMPONENT REMOVAL/INSTALLATION [2WD (US)] .) (See REAR DRIVE SHAFT REMOVAL/INSTALLATION (US) .) Is there foreign matter on the ABS sensor rotor?	Yes	Repair or replace the ABS sensor rotor and perform the repair completion verification. (See WHEEL HUB COMPONENT REMOVAL/INSTALLATION [2WD (US)] .) (See REAR DRIVE SHAFT REMOVAL/INSTALLATION (US) .)
5		No	Go to the next step.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED Install/connect the part removed/disconnected during the troubleshooting procedure. Clear the DTC recorded in the memory. (See CLEARING DTC .) Start the engine and drive the vehicle at 20 km/h {12 mph} or more. Perform the DTC inspection for the DSC HU/CM. (See DTC INSPECTION .) Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW (US) .) If the CAN communication is normal, perform the diagnosis from Step 1. If the malfunction recurs, replace the DSC HU/CM, then go to the next step. (See DSC HU/CM REMOVAL/INSTALLATION [L.H.D. (US)] .)
Repair completion verification 1		No	Go to the next step.
Repair completion verification 2	VERIFY IF OTHER DTCs DISPLAYED Perform the DTC inspection. (See DTC INSPECTION .) Are any DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
Repair completion verification 2		No	DTC troubleshooting completed.
