DTC C1165: Right Rear Wheel Speed Sensor Input Circuit Failure
NOTE:
Wheel speed sensor may also be referred to as brake sensor.
- Check Right Rear Wheel Speed Sensor
Disconnect right rear wheel speed sensor. Measure resistance between speed sensor terminals. If resistance is 800-1400 ohms, go to next step. If resistance is not 800-1400 ohms, replace right rear wheel speed sensor and retest system. - Check For Shorted Sensor
Measure resistance between speed sensor terminal No. 1 and ground. See Figure . If reading is infinite, go to next step. If reading is not infinite, replace right rear wheel speed sensor and retest system. - Check Wheel Speed Sensor Circuitry
Reconnect right rear wheel speed sensor connector. Disconnect ABS control module connector. Connect Breakout Box (014-00322) and ABS Adapter (T90P-50-ALA). Measure resistance between breakout box test terminals No. 1 and 17. If resistance is 800-1400 ohms, go to next step. If resistance is not 800-1400 ohms, go to step 7). - Check Red/Pink Wire For Short To Ground
Measure resistance between breakout box test terminals No. 8 and 17. If resistance is 10 k/ohms or less, go to next step. If resistance is greater than 10k/ohms, go to step 6). - Check Pink/Black Wire For Short To Ground
Disconnect right rear wheel speed sensor connector. Measure resistance between breakout box test terminals No. 8 and 17. If resistance is 10 k/ohms or less, repair short to ground in Red/Pink wire. If resistance is greater than 10 k/ohms, repair short to ground in Pink/Black wire. - Check For DTC(s)
Ensure all connectors are properly connected. Using New Generation Star (NGS) tester (007-00500), clear DTC(s). Turn ignition off, then turn ignition on. Perform ABS self-test. See ON-DEMAND SELF-TEST under DIAGNOSIS. Retrieve all stored DTC(s). If DTC C1165 is retrieved, replace ABS control module. If DTC C1165 is not retrieved, check all connections for corrosion, bent terminals or loose connections. Correct any condition which may cause intermittent failure. After repair, retest system. - Check Red/Pink Wire For Short To Battery
Measure voltage between breakout box terminals No. 8 and 17. If any voltage is indicated, go to next step. If no voltage is indicated, go to step 9). - Check Pink/Black Wire For Short To Battery
Disconnect right rear wheel speed sensor. Measure voltage between breakout box terminals No. 8 and 17. If any voltage is indicated, repair short to battery power in Red/Pink wire. If no voltage is indicated, repair short to battery power in Pink/Black wire. After repair, retest system. - Check Red/Pink Wire For Open
Measure resistance between breakout box terminal No. 17 and Red/Pink wire terminal of right rear wheel speed sensor connector. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Red/Pink wire and retest system. - Check Pink/Black Wire For Open
Measure resistance between breakout box terminal No. 1 and Pink/Black wire terminal of right rear wheel speed sensor connector. If resistance is 5 ohms or less, repair short between Red/Pink wire and Pink/Black wire in right rear wheel speed sensor circuit. If resistance is greater than 5 ohms, repair open in Pink/Black wire. After repair, retest system.
