Anti-Lock Warning Light Inoperative

  1. If all other warning lights illuminate with ignition switch on, go to step  3 . If other warning lights do not illuminate, check fuse No. 8 in main fuse panel. If fuse is blown, correct cause of blown fuse, and replace fuse. If fuse is okay, go to next step.
  2. Remove instrument cluster. Turn ignition switch on. Using a DVOM, measure voltage between ground and instrument cluster ANTI-LOCK warning light terminal. See WIRING DIAGRAMS  . If battery voltage is present, repair or replace instrument cluster. If battery voltage is not present, repair wiring between fuse and instrument cluster. See WIRING DIAGRAMS  .
