DTC C003A-14

DTC C003A-14 : Right Rear Wheel Speed Sensor Circuit Failure (Circuit Short To Ground or Open)

NOTE

Initial Diagnosis:
The initial on-board diagnosis occurs right after the vehicle condition is turned to the ON mode, and the ABS, VSA, and brake system indicator (amber) come on, and continues until the indicator goes off.
Regular Diagnosis:
The regular on-board diagnosis begins right after the ABS, VSA, and brake system indicator (amber) go off, and it continues until the vehicle condition is turned to the OFF (LOCK) mode.
Review "How to Troubleshoot the VSA System" before doing the DTC troubleshooting procedure.
Test-drive the vehicle according to local traffic conditions and regulations. Do not test-drive on a lift unless specified.
The possible causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

Confirmation Procedure	Basic Condition: 12 volt battery voltage 8.5 V or more Operating Condition: Start the engine. Test-drive the vehicle at 19 mph (30 km/h) or more for at least 2 seconds.(Drive the vehicle on the road, not on a lift. Be careful of the surrounding traffic conditions.)
Execution	Initial Diagnosis/Regular Diagnosis
Duration	About 2 seconds
DTC Type	1 drive cycle Brake system indicator (red) on (If multiple wheel failures are detected) Brake system indicator (amber) on ABS indicator on VSA indicator on
Fail Safe Action	Stop EBD function (If multiple wheel failures are detected) Stop ABS function Stop engine drag torque control function Stop TCS function Stop VSA function Stop agile handling assist function Stop brake assist function Stop hill start assist function Stop automatic brake hold control function Stop starting assist brake function* 1 Stop ACC function* 2 Stop CMBS function* 2 Stop parking cooperation assist function* 3
Possible Cause	Open, Short to ground, or Short to power between the VSA modulator-control unit and the right-rear wheel speed sensor (RR R ABS SNSR+, RR R ABS SNSR- lines) Short to another line between the VSA modulator-control unit and the right-rear wheel speed sensor (RR R ABS SNSR+, RR R ABS SNSR- lines) Right-rear wheel speed sensor failure VSA modulator-control unit internal failure
