Body Control Module (BCM)
Ignition 0: Displays 0.0-25.5 V.
This parameter is the system voltage measured by the BCM at the BCM battery
input.
Ignition 1: Displays 0.0-25.5 V.
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 V.
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.
