Circuit Description

The instrument panel cluster (IPC) monitors the ignition 0 voltage circuit, the ignition 1 voltage circuit, and the crank voltage circuit. The ignition 0 voltage circuit is active (circuit is high) when the ignition switch is in accessory, on, or start. The ignition 1 circuit is active (circuit is high) when the ignition switch is in on or start. The crank voltage circuit is active (circuit is high) when the ignition switch is in start.
