Scan Tool Data Definitions
Body Control Module (BCM)

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.

Powertrain Control Module (PCM)
Ignition 1: Displays 0.0 - 25.5 Volts. This parameter is the system voltage measured by the BCM at the BCM battery input.
TFP: Displays PARK/Neutral/Drive 1/Drive 2/Drive 3/Drive 4/Reverse. This parameter displays the current gear position of the transaxle.
