DDM/ PDM

WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.

The DDM and PDM supply voltage and ground to illuminate their respective exterior mirror BLIS®/ CTA LED based on messages received from the SODL and SODR. The modules are capable of storing Diagnostic Trouble Codes (DTCs) for the BLIS® or CTA system when a concern exists. The DDM and PDM communicate through the MS-CAN.

The DDM and PDM require PMI when replaced. Refer to: Module Configuration - System Operation and Component Description .
