For 1990-2009 cars only
Battery 1: The scan tool displays 0-20 Volts. The scan tool displays the voltage as received on the battery positive voltage circuit of the BCM.
Generator F-Terminal (PCM): The scan tool displays the percentage of the field current.
Generator L-Terminal (ECM): The scan tool displays Enabled/Disabled. The scan tool displays Disabled until the engine is running, then the ECM supplies then the percentage value varies depending on electrical loads.
Generator L-Terminal (PCM): The scan tool displays Active/Inactive. The scan tool displays Inactive until the engine is running, then the PCM supplies then the percentage value varies depending on electrical loads.
Ignition 1 (ECM/PCM): The scan tool displays 0-20 Volts. The scan tool displays the voltage as received on the Ignition 1 circuit to the ECM/PCM.
Transmission Range (ECM): The scan tool displays Reverse, 2nd, Drive, Park, Neutral, 1st and 3rd. The scan tool displays the switch status of the transmission (L61).
TR Sw. (PCM): The scan tool displays Invalid, Park, Reverse, Neutral, Drive, Intermediate and Low The scan tool displays the switch status or the transmission (L66).
