Ignition 0: Displays 0.0 - 25.5 Volts. This parameter is the system voltage measured by the BCM at the BCM battery input.
Ignition 1: Displays 0.0 - 25.5 Volts. This parameter is the system voltage measured by the BCM at the BCM ignition 1 voltage input.
Park (BTSI) Relay: Displays indicates ON when the body control module applies a ground to the automatic transmission shift lock control solenoid.
