Personalization Option - Dash Integration Module (DIM)

WARNING: This page is about a different car, the 2008 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.

Front door modules also cannot perform memory mirror functions unless the Personalization Option in the dash integration module (DIM) is activated. The DIM stores the Personalization Option setting provided at the assembly plant and reports the setting to both front door modules, as well as other receiving modules, each time the ignition switch is cycled to RUN. The front door modules store the Personalization Option setting provided by the DIM and examine it before making a memory mirrors adjustment.

The Personalization Option setting stored within the front door modules will not change until the Personalization Option setting within the DIM is changed and the ignition switch then cycled to RUN.

If the Personalization Option is activated on a vehicle that is not equipped with memory, the door modules will erroneously set DTCs B1586 and B1591.
