DDM/ PDM

The DDM and PDM supply voltage and ground to illuminate their respective exterior mirror BLIS®/ CTALED 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.
