Test B: Right Rear Sensor & Circuit
- DTC 32 & 42: Check Right Rear Wheel Sensor Circuits Resistance
Disconnect 16-pin connector on jumper from HCU assembly to chassis harness connector. See COMPONENT LOCATIONS
. Measure resistance between HCU assembly 16-pin chassis harness connector terminals No. 5 (Tan/Light Green wire) and 9 (Brown wire). See Figure
. If resistance is 2187-2673 ohms, go to step 3). If resistance is not 2187-2673 ohms, go to next step.
- Check Right Rear Wheel Sensor
Disconnect right rear wheel sensor harness connector. Measure resistance between wheel sensor connector terminals. If resistance is 2187-2673 ohms, repair circuit No. 492 (Brown wire) or No. 494 (Tan/Light Green wire) between wheel sensor and HCU 16-pin harness connector. If resistance is not 2187-2673 ohms, replace right rear wheel sensor.
- Check Wiring At Jumper Harness
Remove cover from HCU. Disconnect jumper harness from ABS control module. Check for broken or damaged wire in jumper harness. If wires are okay, go to next step. If wires are not okay, replace broken or damaged wire in jumper harness.
- Check Left Rear Wheel Sensor Circuit Short To Ground
Remove cover from HCU. Disconnect jumper harness from ABS control module. Using a DVOM, check resistance between ABS control module 14-pin connector terminal No. 6 (Tan/Light Green wire) and ground. Also check resistance between terminal No. 7 (Brown wire) and ground. If resistance is more than 5 ohms, go to next step. If resistance is 5 ohms or less, Repair Tan/Light Green wire and Brown in jumper harness. If wires are okay replace right rear wheel sensor.
- Check Right Rear Wheel Speed Sensor Air Gap
Remove right rear wheel and check for damage to sensor or sensor indicator. Verify air gap between sensor and sensor indicator is within 0.024-0.063" (.6-1.6 mm). If air gap is not as specified, check for excessive axle bearing end play and adjust sensor position as required. If air gap is okay and warning light remains ON constantly, replace ABS control module.
