Abs Warning Light Does Not Come On
- If light does not come on when ignition is on, check bulb. Check back-up light fuse No. 15 (10 amps) in underdash fuse relay box. Check Yellow wire between back-up light fuse and instrument panel.
- Check Blue/Red wire between instrument panel and ABS control unit. Check ABS control unit ground circuit. If circuits are okay, check ABS control unit connectors. If connectors are okay, install known-good ABS control unit and recheck.
