Diagnostic Procedure

NOTE: If none of the ABS/VSC indicators light up when ignition is turned on, check for defective GAUGE NO. 1 fuse (10-amp) in driver's underdash fuse block, or open circuit in Red/Black wire between GAUGE NO. 1 fuse and instrument cluster. See WIRING DIAGRAMS .
  1. If ABS warning light stays on, go to next step. If ABS warning light does not illuminate, check light bulb and replace as necessary. If bulb is okay, diagnose combination meter. See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT.
  2. Remove active lamp relay, located behind driver's side dash. See Figure. Substitute known-good active lamp relay and retest system. If ABS warning light goes out, replace defective active lamp relay. If ABS warning light stays on, reinstall old active lamp relay. Locate and repair faulty circuit between ABS warning light, active lamp relay or Skid Control ECU. See WIRING DIAGRAMS .
