Note
• When only the driving wheels are rotated while the vehicle is jacked up, DTCs C0037:29 and C003A:29 are input to the memory.



Outline

System malfunction location

DTC C0039:07

ABS wheel-speed sensor (RR)

DTC C003A:07, C003A:29, C003A:2F, C003A:37 or C003A:64

ABS wheel-speed sensor (RR), ABS wheel-speed sensor rotor
Detection condition
• C0039:07
― While driving at a vehicle speed of 14 km/h {8.7 mph} or more, the DSC HU/CM detects a periodic pulse deficiency in the signal wave pattern of the ABS wheel-speed sensor (RR).
• C003A:07
― The DSC HU/CM detects a sudden change in the wheel acceleration on the right rear wheel.
• C003A:29
― While driving at a vehicle speed of 20 km/h {12 mph} or more, the DSC HU/CM detects that the wheel speed signal of the right rear wheel is lower than the specification compared to the other wheel speed signals.
• C003A:2F
― While driving, the DSC HU/CM detects any of the following conditions.
• Amount of change in wheel speed of right rear wheel is larger than specification
• ABS control corresponding to right rear wheel continues for 28 s or more
• C003A:37
― While driving, the DSC HU/CM detects that the wheel speed signal of the right rear wheel is extremely high.
• C003A:64
― While driving at a vehicle speed of 20 km/h {12 mph} or more, the DSC HU/CM detects that the wheel speed signal of the right rear wheel is higher than the specification compared to the other wheel speed signals.
Fail-safe
Refer to “DTC Table” and “Fail-safe Function Malfunction Contents Table”. (See DTC TABLE [DSC HU/CM (US)].)
Possible cause
• Continuous ABS operation
• ABS wheel-speed sensor (RR) connector or terminals malfunction
• DSC HU/CM connector or terminals malfunction
• ABS sensor rotor malfunction (missing ABS sensor rotor teeth due to foreign material obstruction)
• ABS wheel-speed sensor (RR) or ABS sensor rotor installation malfunction (If the ABS sensor rotor is installed at an angle, it may cause output of abnormal wave pattern at high speeds.)
• Excessive clearance between the ABS wheel-speed sensor and sensor rotor
• ABS wheel-speed sensor (RR) malfunction
• DSC HU/CM malfunction



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.
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.
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.
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.
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].) (See REAR DRIVE SHAFT REMOVAL/INSTALLATION.)
• 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].)
(See REAR DRIVE SHAFT REMOVAL/INSTALLATION.)
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)].)
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.
No
DTC troubleshooting completed.
