Right Front Sensor Circuit Failure
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagram, see WIRING DIAGRAM.
- Using scan tool, read and record all Wheel Speed Sensor (WSS) trouble codes. If scan tool does not display RIGHT FRONT SENSOR CIRCUIT FAILURE, go to TEST 22A. If scan tool displays RIGHT FRONT SENSOR CIRCUIT FAILURE, go to next step.
- Inspect WSS for damage or contamination. If WSS is faulty, replace WSS. Perform TEST VER-1A. If WSS is okay, go to next step.
- Turn ignition off. Disconnect CAB 37-pin connector. See Figure . Inspect, clean or repair connector as necessary. Turn ignition on. Using scan tool in voltmeter mode, check voltage on CAB connector terminal No. 1 (White wire). See Figure . If any voltage is present, repair short to power in White wire. Perform TEST VER-1A. If no voltage exists, go to next step.
- Using scan tool, check voltage on CAB connector terminal No. 6 (White/Dark Blue wire). If any voltage is present, repair short to power in White/Dark Blue wire. Perform TEST VER-1A. If no voltage exists, go to next step.
- Turn ignition off. Using scan tool in ohmmeter mode, check resistance of CAB connector terminal No. 1 (White wire). If resistance is less than 5 ohms, repair short to ground in White wire. Perform TEST VER-1A. If resistance is more than 5 ohms, go to next step.
- Using scan tool, check resistance of CAB connector terminal No. 6 (White/Dark Blue wire). If resistance is less than 5 ohms, repair short to ground in White/Dark Blue wire. Perform TEST VER-1A. If resistance is more than 5 ohms, go to next step.
- Using an external ohmmeter, check resistance between CAB connector terminals No. 1 (White wire) and No. 6 (White/Dark Blue wire). If resistance is 950-1250 ohms, replace CAB. Perform TEST VER-1A. If resistance is not 950-1250 ohms, go to next step.
- Disconnect right front WSS connector. Inspect, clean or repair connector as necessary. Using an external ohmmeter, check resistance between WSS male connector terminals. If resistance is not 950-1250 ohms, replace WSS. Perform TEST VER-1A. If resistance is 950-1250 ohms, go to next step.
- Using an external ohmmeter, check resistance of White wire between CAB connector terminal No. 1 and WSS female connector. If resistance is more than 5 ohms, repair open in White wire. Perform TEST VER-1A. If resistance is less than 5 ohms, repair open in White/Dark Blue wire. Perform TEST VER-1A.
