Abs Function Test

NOTE: BRAKE warning light should remain on if parking brake is applied and ignition is turned on.
  1. Turn ignition on and note operation of ANTI-LOCK indicator light and BRAKE warning light on instrument panel. ANTI-LOCK indicator light and BRAKE warning light should come on for 2 seconds and then go off.
  2. If ANTI-LOCK indicator light does not come on for 2 seconds and then go off, see SELF-CHECK CHARTS for appropriate test. If ANTI-LOCK indicator light remains on, check for stored diagnostic codes. See RETRIEVING CODES under DIAGNOSIS & TESTING.
  3. If no diagnostic codes are stored, but ANTI-LOCK indicator light remains on, see SELF-CHECK CHARTS for appropriate test.
  4. If ANTI-LOCK indicator and BRAKE warning lights operate correctly in self-check, but wheels lock with hard stops, see SELF-CHECK CHARTS for appropriate test.
