Glow Plug Relay: Description and Operation

Glow Plug Relay

The glow plug relay is mounted at the rear of the right cylinder head, which is a solid state device that operates the glow plugs.

The PCM uses an ignition voltage signal in order to control the solid state circuitry of the glow plug relay.
