B DTC 32, 42 RH Rear Sensor and Circuit

B1- Check Resistance Circuits 494 and 492
- Disconnect 16-pin connector C140 on jumper from ABS assembly to wire harness.
- Measure resistance between pins C140-5 and C140-9 on Wire harness side connector.
- Is resistance between 2187 and 2673 ohms?
YES - Go to B3.
NO - Go to B2.

B2- Check Anti-Lock Sensor Resistance
- Disconnect RH rear sensor from wire harness.
- Measure resistance between pins C319M-1 and C319M-2 on sensor.
- Is resistance between 2187 and 2673 ohms?
YES - Service or replace cable harness circuit 492 (BR) or 494 (T/LG).
NO - Replace RH rear anti-lock brake sensor. Wheel Speed Sensor

B3- Check Circuits 492 and 494 at Jumper Harness
- Remove cover from hydraulic control module.
- Disconnect jumper harness from anti-lock brake control module.
- Check for broken or damaged wire in jumper between C140-9 (16-pin side) and C142-7 (15-pin side) or between C140-5 (16-pin side) and C142-6 (15-pin side).
- Are both wires OK?
YES - Go to B4.
NO - Service or replace broken or damaged wire in jumper.

B4- Check Anti-Lock Sensor For Short To Ground
- Remove cover from hydraulic control unit.
- Disconnect jumper harness from anti-lock brake control module.
- Check for a short from ground to Pin C142-6.
- Check for a short from ground to Pin C142-7.
- Is resistance 5 ohms or less?
YES - Service or replace jumper circuit 494 (T/LG) or 492 (BR), or RH rear anti-lock brake sensor.
NO - Go to B5.

B5- Check RH Rear Anti-lock Brake Sensor Air Gap
- Remove the RH rear wheel and tire.
- Check for damage to the rear anti-lock brake sensor or anti-lock sensor indicator.
- Check for objects sticking to the rear anti-lock brake sensor or anti-lock sensor indicator.
- Check air gap between the sensor and indicator. Gap should be 0.6-1.6 mm (0.024-0.063 inch).
- Check for excessive wheel bearing end play. Refer to Transmission and Drivetrain.
- Are the conditions OK?
YES - If the light is coming on all the time, replace the anti-lock brake control module.
NO - Service condition as required.
