Speedometer & Odometer Do Not Operate

  1. Check VSS and VSS buffer. See VEHICLE SPEED SENSOR & BUFFER  under TESTING. If VSS and VSS buffer are okay, turn ignition off. Disconnect instrument cluster connector and VSS buffer connector.
  2. Check resistance of Light Blue/Black wire between instrument cluster connector and VSS buffer connector. If resistance is not about 0 ohms, repair Light Blue/Black wire. If resistance is about 0 ohms, replace instrument cluster.
