Resistance Check

Ensure ignition is off. Disconnect ABS control module. Ensure hydraulic actuation assembly is connected. Set VOM on 200-ohm scale. Measure resistance between Red/Yellow wire at ABS control module connector and ground. See Figure . If resistance is less than one ohm, go to PINPOINT TESTS WL-1  through WL-3 . If resistance is greater than one ohm, service wire between ABS control module and hydraulic actuation assembly.
