Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Driver Door Module (DDM)
The DDM monitors the inputs and provides outputs and diagnostic information for the following multiple vehicle systems, including the:
- Power door locks
- Remote keyless entry (RKE) system
The DDM monitors all of the door ajar switches as they are hardwired to the module. This door ajar information is sent through the standard corporate protocol (SCP) network to the instrument cluster (IC), which sends the door ajar information to the vehicle dynamics module (VDM) on the high speed controller area network (HS-CAN). Diagnostic information is retrieved from the DDM on the standard corporate protocol (SCP) communication network. The power door locks and the RKE system are all controlled by the DDM. The DDM also receives an input from the luggage compartment lid release switch and operates the luggage compartment lid release solenoid unless the vehicle is equipped with a power luggage compartment lid. In this case, the DDM sends a signal to the luggage compartment lid module, which will operate the luggage compartment lid release solenoid.
