Light Retractor Control Relay

  1. Turn the light control switch off. With connector connected, ground the terminal No. 14. Check that the headlights rise with the light illuminated. Quickly ground terminal No. 3. The light will go out, but the headlight should remain up. When terminal No. 3 is taken off ground, the headlights should flip down.
    NOTE: If operation is not as specified, replace the relay.
  2. Disconnect the relay and inspect the connector on the wire harness side. See Fig 1 and the following table.
