Operational Test (929)

  1. Start engine, and observe ANTI-LOCK light. Light should illuminate for a few seconds. If light does not illuminate as described, remove instrument cluster. Connect 12 volts to terminal "J" of instrument cluster connector I-06. See Fig 3 . Using a jumper wire, connect terminal "E" of instrument cluster connector I-08 to negative ground. ANTI-LOCK light should illuminate. If light does not illuminate, check bulb. If bulb is okay, check meter fuse and wiring harness.
  2. Install instrument cluster, and recheck warning light operation. If light still does not illuminate for a few seconds, check wiring harness between ANTI-LOCK light and control unit and between ANTI-LOCK light and hydraulic unit. Check operation of hydraulic unit valve relay.
