Driver Door Module (DDM)

Driver Door Module (DDM)









Removal

NOTICE: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.

NOTE: Prior to the replacement of the Driver Door Module (DDM), it is necessary to upload the module configuration information to the scan tool. This information must be downloaded into the new DDM after installation. For additional information, refer to Information Bus.

NOTE: The Tire Pressure Monitoring System (TPMS) functionality is integral to the DDM.

NOTE: The steps included in the DDM removal and installation procedure are critical to restoring the vehicle security and TPMS to normal operation. A new DDM is delivered in a manufacturing mode with 6 pre-set DTCs related to the TPMS. To clear the DTCs, successful configuration of the DDM must occur, followed by successful TPMS sensor training, and a successful self-test, including clearing of the DTCs. The DTCs are as follows:
- B2477 (Module Configuration Failure)
- B2868 (Left Front Tire Pressure Sensor Fault)
- B2869 (Right Front Tire Pressure Sensor Fault)
- B2870 (Right Rear Tire Pressure Sensor Fault)
- B2871 (Left Rear Tire Pressure Sensor Fault)
- C2780 (ECU in Manufacturer Sub-State)

1. NOTE: This step is only necessary if a new DDM is being installed.

Upload the module configuration information from the DDM into the scan tool. For additional information, refer to Information Bus.

2. Remove the driver door trim panel.

3. Disconnect the DDM electrical connectors.

4. Remove the 2 screws.

5. Release the locking tab and remove the DDM.

Installation

1. Position the DDM and engage the locking tab.

2. Install the 2 screws.

3. Connect the electrical connectors.

4. NOTE: If the DDM was not replaced, this is the last step that is necessary.

Install the driver door trim panel.

5. NOTE: When successful, this step provides the calibration necessary for the DDM operation and clears DTC B2477. The clearing of this DTC indicates the calibration data has been successfully downloaded to the new DDM.

NOTE: The following steps are necessary only if the DDM is being replaced.

Download the DDM configuration information from the scan tool. For additional information, refer to Information Bus.

6. NOTE: When successful, this step clears DTCs B2868, B2869, B2870 and B2871. The clearing of these DTCs indicates the DDM has recognized the tire pressure sensors during the training procedure.

Train the tire pressure sensors. For additional information, refer to Wheels and Tires.

7. NOTE: DTC C2780 does not clear if any other DTCs are present in the DDM. When successful, this step clears DTC C2780.

Carry out the DDM self-test (must include an on-demand self-test) by clearing DTCs, and then retrieving DTCs to confirm all DTCs have been cleared.
