For 1990-2009 cars only
Accy/RAP Relay Command: The scan tool displays the commanded state of the RAP relay. The scan tool displays ON when the BCM provides voltage to the RAP relay control circuit.
Battery Voltage: This parameter displays the amount of battery voltage available to the body control module (BCM).
Currant Power Mode: This parameter displays the power mode defined by the power mode master and communicated to the modules that require this information. There are 4 possible display parameters depending on the ignition switch position. These are Off, Accessory, Run, and Crank Request. This parameter should match the actual ignition switch position.
HS Comm. Cmd.: The scan tool displays the commanded state of the serial data communication enable circuit output. The scan tool displays ON when the BCM provides voltage to the circuit. This voltage output acts as a wakeup signal for the electronic brake control module (EBCM).
Ign. Off/Run/Crank: The BCM uses this data input signal from the off/run/crank voltage circuit (1 of 3 circuits) in order to determine the power mode (ignition switch position). There are 4 possible display parameters depending on the ignition switch position. These are Key Out/Run, Key In/Off, Crank, or Run.
Ignition Accessory/Run: The BCM uses this data input signal from the accessory voltage circuit (1 of 3 circuits) in order to determine the power mode (ignition switch position). Active is displayed when the ignition switch is in the Accy or Run positions.
Ignition Run/Crank: The BCM uses this data input signal from the ignition 1 voltage circuit (1 of 3 circuits) in order to determine the power mode (ignition switch position). Active is displayed when the ignition switch is in the Run or Crank positions.
Key in Ignition Status: The scan tool displays the ignition key in/out status. The parameters are Key Out, and Key In.
Powertrain HS Comm. Cmd.: The scan tool displays the commanded state of the accessory wake up serial data circuit output. The scan tool displays ON when the BCM provides voltage to the circuit. This voltage output acts as a wakeup signal for the powertrain control module(s).
Run/Crank Relay Command: The scan tool displays the commanded state of the run/crank relay. The scan tool displays ON when the BCM provides voltage to the run/crank relay control circuit.
Battery Voltage: This parameter displays the amount of battery voltage available to the body control module (BCM).
