C3 Antilock Electronic Control Module Ground

NOTE: When checking resistance in the RABS system, always disconnect the battery to starter relay cable. Improper resistance may occur with the vehicle battery connected.

- Check for good antilock electronic control module ground:

- Remove harness connector from antilock electronic control module.

- Set ohmmeter on the 200 ohm scale.

- Check for resistance between antilock electronic control module harness connector Pin 4 and chassis ground.

- Is resistance less than 1.0 ohm?

YES -- Reconnect battery ground cable. Go to C4.

NO -- Check for open in antilock electronic control module ground wire. Check for loose, dirty or broken connector pins. Repair as necessary. Repeat System Pre-Check.
