Scan Tool Data Definitions

The scan tool displays the part number for the Door Module (DDSA, DDM, PFDM, LMDM, RMDM, LRDM, or RRDM).

The scan tool displays 0 to 25.0 volts. This is the current battery voltage level at the door module.

The scan tool displays the calibration or program revision level used in the PROM.

The scan tool displays the first partition of the door module serial number.

The scan tool displays the second partition of the door module serial number.

The scan tool displays the third partition of the door module serial number.

The scan tool displays the last partition of the door module serial number.

The scan tool displays Inactive/Active. This is the state of the door switches backlighting as detected by the associated door module. When the door switches are illuminated, the scan tool displays Active in the appropriate door modules data list. When the door switches are not illuminated, the scan tool displays Inactive in the appropriate door modules data list.

The scan tool displays a number representing the level of hardware incorporated into the Door Module (DDM, PFDM, LMDM, RMDM, LRDM, or RRDM).

The scan tool displays Off/On. This is the driver door module (DDM) or the passenger front door module (PFDM) output to the associated mirror. When the DDM or the PFDM supplies voltage and ground to the associated outside rearview mirror heating element, the scan tool displays On in the appropriate door modules data list. When the DDM or PFDM is not supplying voltage and ground to the associated outside rearview mirror heating element, the scan tool displays Off.

The scan tool displays a number representing the day of the year the module selected was built.

The scan tool displays 0.25 - 5.50 volts (DDM and PFDM only). This is the mirror horizontal position sensor feedback voltage as detected by the associated front door module, i.e. driver door module (DDM), or passenger front door module (PFDM). The voltage varies directly with the horizontal position of the associated outside rearview mirror.

The scan tool displays Idle/Driver 1/Driver 2/Exit. This is the state of the memory function switch as detected by the driver door switch assembly (DDSA). When a memory function switch button is pressed, the scan tool momentarily displays the function pressed.

The scan tool displays Idle/In. This is the state of the outside rearview mirror power fold switch as detected by the driver door switch assembly (DDSA). When the power fold switch is not being operated the scan tool displays Idle.

The scan tool displays Idle/Up/Down/Left/Right/Fold In/Fold Out. This is the driver door module (DDM) or passenger front door module (PFDM) output to the associated outside rearview mirror. When the DDM or the PFDM supplies voltage and ground to the associated driver or passenger mirror motor to move the mirror up, down, left, or right, or to Fold In or Fold Out, the scan tool displays the corresponding direction in the appropriate door modules data list. When the DDM or the PFDM is not supplying voltage and ground to a mirror motor, the scan tool displays Idle.

The scan tool displays Idle/Driver/Passenger. This is the state of the mirror select switch as detected by the driver door switch assembly (DDSA). The display indicates which mirror, if any, the operator has selected for adjustment.

The scan tool displays Up/Down/Left/Right/Up-Left/Up-Right/Down-Left/Down-Right. This is the state of the mirror position adjustment switch as detected by the driver door switch assembly. When the mirror position adjustment switch is operated in any of these directions, the scan tool displays the corresponding direction.

The scan tool displays the module identity. The driver door module and the left rear door module display DDM/LRD as an Input. The passenger front door module and the right rear door module display PDM/RRD as an Input. On vehicles w/V4U, the left middle door module and the right middle door module display RMD/LMD as an Input.

The scan tool displays driver 1 or driver 2. This is the identity of the current driver as detected by the driver door switch assembly (DDSA).

This is the state of the personalization option as it is stored in the Dash Integration Module (DIM). When Personalization Option is selected, the scan tool displays the directions to activate or deactivate the personalization option. The personalization option is normally set to the activated state during assembly of the vehicle.

The scan tool displays the PROM ID of the driver door switch assembly (DDSA).

The scan tool displays the four digit number of the software incorporated into the Door Module (DDM, PFDM, LMDM, RMDM, LRDM, or RRDM).

The scan tool displays 0.25 - 5.50 volts (DDM and PFDM only). This is the mirror vertical position sensor feedback voltage as detected by the associated front door module, i.e. driver door module (DDM), or passenger front door module (PFDM). The voltage varies directly with the vertical position of the associated outside rearview mirror.

The scan tool displays the four digit year of build for the module selected.
