Scan Tool Data Definitions

The Driver Door Module (DDM) and Passenger Door Module (PDM) scan tool data definitions are a brief description of each of the power window related parameters displayed within the scan tool data display for the DDM/PDM.

Base Software P/N

This is the part number stored within the PDM of the base software set required to activate the DDM/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 DDM/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 DDM/PDM's high current outputs such as the power windows.

Calibration P/N

This is the part number stored within the DDM/PDM of the calibration set. The calibration software sets the operational ranges and option levels for each of the DDM/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.

Left Front Window Status

This parameter indicates the status of the left front window.

Left Rear Window Status

This parameter indicates the status of the left rear window.

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 Lockout

This parameter indicates the current status of the window lockout switch.

Window Lockout LED

This parameter indicates the commanded state of the window lockout indicator.

Window Motor Current

This parameter indicates the active status of the window lockout feature.

Window Motor Output

This parameter reflects the state of the DDM/PDM output to the window motor.

The Body Control Module (BCM) scan tool data definitions are a brief description of each of the power window related parameters displayed within the scan tool data display for the BCM.

Left Rear Window Up Relay

This parameter indicates the commanded state of the left rear window up relay.

Left Rear Window Down Relay

This parameter indicates the commanded state of the left rear window down relay.

Right Rear Window Up Relay

This parameter indicates the commanded state of the right rear window up relay.

Right Rear Window Down Relay

This parameter indicates the commanded state of the right rear window down relay.

The HVAC Control Module scan tool data definition is a brief description of the rear window defroster related parameter displayed within the scan tool data display for the HVAC Control Module.

Rear Defrost Switch

This parameter indicates the current status of the rear defrost switch.

The Liftgate Module (LGM) scan tool data definitions are a brief description of each of the rear window defroster related parameters displayed within the scan tool data display for the BCM.

Defog Relay Voltage

The scan tool displays the voltage supplied to the rear defogger grid.

Rear Defog Requested

The scan tool displays Yes/No. When the window defogger switch is pressed, a request from HVAC control module is sent to LGM. This parameter indicates if the request was received.
