Scan Tool Data Definitions
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.
