NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagram, see wiring diagram.
- Using scan tool in voltmeter mode, check voltage on Brown/Black wire at ABS relay connector. If reading is less than one volt, go to TEST 16C. If reading is more than one volt, go to next step.
- Turn ignition off. Disconnect CAB 60-pin connector. Inspect, clean and repair connector as necessary. Using scan tool, check voltage on Brown/Black wire at ABS relay connector. If reading is less than one volt, replace CAB. Perform TEST VER-1A. If reading is more than one volt, repair short to power in Brown/Black wire. Perform TEST VER-1A.
