Power/Ground to Anti-Lock Brake System (ABS) Module

If the fuse has failed:

1. Check the weather packing of the power connector to the ABS module C135.
2. Remove the central junction box (CJB) fuse 602 (60A).
3. Measure the resistance between the outside pin of the CJB fuse 602(60A), circuit 532 (OG/YE), and ground.
4. Spray with water and wiggle the wiring between the power distribution box and the ABS module.
5. If any continuity is measured, repair or install new wiring.

Check for opens in wiring:

1. Disconnect the ABS module C135.
2. While measuring the voltage between ABS module C135 pins 9 and 25, circuit 532 (OG/YE), and the negative battery post, wiggle the wiring harness.
3. If the voltage momentary drops below 10 volts while the harness is wiggled, repair or install new wiring.
4. While measuring the resistance between the ABS module C135 pins 8 and 24, circuit 530 (LG/RD), and ground, wiggle the wiring harness.
5. If the resistance momentarily goes above 5 ohms while the harness is wiggled, repair or install new wiring.
