Operational Test

  1. Start engine and observe ABS warning light. Light should illuminate for a few seconds. If light does not illuminate as described, disconnect hydraulic unit connector, and turn ignition on. Using a jumper wire, connect terminal "G" (Gray wire) of hydraulic unit connector to ground. See Figure .
  2. If ABS warning light illuminates, inspect ABS control unit or hydraulic unit. If light does not illuminate, turn ignition to LOCK position, and reconnect hydraulic unit connector. Remove instrument cluster. Remove and check ABS warning light bulb. Replace bulb if necessary. If bulb is okay, go to next step.
  3. Disconnect instrument cluster connector No. 1 (White). Turn ignition on. Using a jumper wire, connect terminal 1B (Gray wire) of instrument cluster connector No. 1 (White) to ground.
