Ignition 1 on

Yes/No: The ignition 1 ON parameter indicates when the VCM is detecting Ignition voltage. The normal ignition voltage is approximately 13.8 volts, but may vary between 11-16 volts. The VCM monitors the ignition voltage to compensate for low voltage operation of the injectors and to increase the dwell time of the ignition coil.
