SCAN TOOL DATA DEFINITIONS

Battery Voltage Signal: The scan tool displays 0-20 Volts. The scan tool displays the voltage as received by the Module or the 72-08 battery voltage message from the BCM over class 2 lines.

Crank Request: The scan tool displays Off, Accessory, Run and Crank Request. The scan tool displays the status of the crank request at the body control module (BCM).

Crank Request Signal: The scan tool displays Yes/No. The scan tool displays No until the ignition is placed into the START position then Yes is displayed.

Generator Lamp Command: The scan tool displays On/Off. The scan tool displays the status of the charge indicator as commanded by the engine control module (ECM)/powertrain control module (PCM).

GEN F-Terminal Command: The scan tool displays 0-100%. The scan tool displays 0-10% until the engine is started and the ECM receives a signal from the generator then OK is displayed.

GEN F-Terminal Signal: The scan tool displays 0-100%. The scan tool displays 0-10% until the engine is started and the PCM receives a signal from the generator then OK is displayed.

GEN L-Terminal Circuit Status: The scan tool displays Incomplete, Short Gnd / Open, Short to B+ or OK. The scan tool displays the status of the GEN L-Terminal circuit.
