Voltage must be in the normal range and the squib is configured for the ORC to test the circuit. The ORC sends out a 40 mA diagnostic current on each squib voltage supply circuit at power up and every 400 ms thereafter while the ignition is in on. The module then monitors the return wire to determine the state of the circuit.
