Main Relay Stuck Off
- Check the ABS F/S RLY (20-amp) fuse in the auxiliary fuse box. Is the fuse okay? If yes, reinstall the fuse, and go to next step. If no, replace the fuse, and recheck.
- Disconnect the ABS control unit 31-pin connector.
- Measure the voltage between the ABS control unit 31-pin connector, terminal No. 18 and body ground. Is there battery voltage? If yes, replace the ABS modulator-control unit. If no, repair open in the wire between the ABS control unit and the ABS F/S RLY (20-amp) fuse.
