Power/Ground to Anti-Lock Brake Control Module

Power/Ground to Anti-Lock Brake Control Module

If the fuse had failed:

a. Check the weather packing of the power connector to the EHCU C1041 (motorhome C130).
b. Remove power distribution box fuse 14 (60A) (motorhome fuse F [60A]).
c. Measure the resistance between the outside pin of power distribution box fuse 14 (60A) (motorhome fuse F [60A]), circuit 532 (O/Y), and ground.
d. Spray with water and wiggle the wiring between the power distribution box and the anti-lock brake control module.
e. If any continuity is measured, repair or replace the wiring.

Check for opens in wiring:

a. Disconnect the EHCU C1041 (motorhome C130).
b. While measuring the voltage between EHCU C1041-2 (motorhome C130-2), circuit 532 (O/Y), and negative battery post, wiggle the wiring harness.
c. If the voltage momentary drops below 10 volts while the harness is wiggled, repair or replace the wiring.
d. While measuring the resistance between the EHCU C1041-1 (motorhome C130-1), circuit 530 (LG/Y), and ground, wiggle the wiring harness.
e. If the resistance momentarily goes above 5 ohms, while the harness is wiggled, repair or replace the wiring.
