The Passenger Door Module (PDM) scan tool data definitions are a brief description of each of the related parameters displayed within the scan tool data display(s) for the PDM.

Back Only Heat Indicator: This data parameter appears in two separate data-lists Inputs and Outputs. While monitoring the inputs for the PDM this parameter reflects the requested state for the back only indicator. When monitoring the outputs the parameter reflects the commanded state for the back only indicator.

Back Only Heat Mode: This data parameter reflects the operating state of the heated seat back only mode of operation. This mode of operation is only available if the heated seat is active or on.

Backlighting Dimming Enabled: This data parameter indicates the status feature. Backlighting is the lighting from behind any text or characters on the PDM switches or faceplate.

Base Software P/N: This is the part number stored within the PDM of the base software set required to activate the PDM. This software set is often referred to as boot software.

Base Software Suffix: This suffix number is the stored indication of the revision level of the base software.

Battery 1 (Low Current): The battery 1 (low current) parameter provides the voltage level on the battery 1 input. Battery 1 is the low current input provides the power for the PDM's microprocessors and the low current outputs.

Battery 2 (High Current): The battery 2 (high current) parameter provides the voltage level on the battery 2 input. Battery 2 is the high current input provides the power for the PDM's high current outputs such as the power windows.

Calibration P/N: This is the part number stored within the PDM of the calibration set. The calibration software sets the operational ranges and option levels for each of the PDM's functions. This software set is often referred to as calibration software or calibration.

Calibration Suffix: This suffix number is the stored indication of the revision level of the calibration. This is often referred to as the CAL ID.

Dimming Enable: The dimming enable reflects the state of the dimming for the various indicators located on the PDM.

Dimming Potentiometer: The dimming potentiometer data parameter reflects the level of lighting, in percent for both the backlighting and indicators for the PDM.

Door Ajar Switch: This parameter reflects the current status of the door ajar switch input to the PDM.

Door Lock Motor: This parameter indicates the current status of the door lock motor.

Door Lock Switch: This parameter indicates the current status of the door lock switch.

Heat Indicator High: This data parameter appears in two separate data-lists inputs and outputs. While monitoring the inputs for the PDM this parameter reflects the requested state for the heat indicator low. When monitoring the outputs the parameter reflects the commanded state for the heat indicator low.

Heat Indicator Low: This data parameter appears in two separate data-lists inputs and outputs. While monitoring the inputs for the PDM this parameter reflects the requested state for the heat indicator low. When monitoring the outputs the parameter reflects the commanded state for the heat indicator low.

Heat Indicator Medium: This data parameter appears in two separate data-lists inputs and outputs. While monitoring the inputs for the PDM this parameter reflects the requested state for the heat indicator medium. When monitoring the outputs the parameter reflects the commanded state for the heat indicator medium.

Heated Seat Mode: This parameter indicates the status of the heated seat feature.

Right Front Window Status: This parameter indicates the status of the right front window.

Memory Switch: This data parameter provides the status of the memory switch.

Mirror 5 Volt Reference: This data parameter provides a status indication of the 5-volt reference circuit for the OSRV position sensors.

Mirror Fold Motor Current: This parameter provides the detected amount of current (in mA) that is required to perform the active mirror fold action.

Mirror Folding Operation: This parameter indicates the mirror fold operation currently in process.

Mirror Heater: This parameter indicates the operational state of the mirror heater.

Mirror Horizontal Position: This parameter provides OSRV mirror horizontal position in volts.

Mirror Motor: This parameter provides information regarding the state of operation the mirror is currently activating.

Mirror Select Switch: This parameter indicates the current mirror select switch position.

Mirror Switch Backlight: The mirror switch backlight data parameter reflects the level of backlighting, in percent for the mirror switch.

Mirror Switch Horizontal: This data parameter provides the current status of the OSRV horizontal position adjustment switch.

Mirror Switch Vertical: This data parameter provides the current status of the OSRV vertical position adjustment switch.

Mirror Vertical Position: This parameter provides OSRV mirror vertical position information in volts.

Program Software P/N: This is the part number stored indication of the revision level of the program software.

Program Software Suffix: This suffix number is the stored indication of the revision level of the program software.

Right Front Window Status: This parameter indicates the status of the right front window.

Right Rear Window Status: This parameter indicates the status of the right rear window.

Window Motor Current: This parameter indicates the active status of the window lockout feature.

Window Motor Output: This parameter reflects the state of the PDM output to the window motor.

Window Switch Backlight: The window switch backlight data parameter reflects the level of backlighting, in percent for the window switch.
