Door Control Module (DCM)
DOOR CONTROL MODULE (DCM)
| Refer to COMPONENT INDEX . |
The DCMs on this vehicle are the Driver Door Module (DDM) and the Passenger Door Module (PDM). These modules are responsible for dimming the exterior mirrors by using a PWM generated signal. The command to change the exterior mirror reflectance is received over the CAN-IHS bus from the BCM.
The DCMs are responsible for discharging the exterior mirror when the EC function is turned off and the PWM duty cycle falls below a calibrated level.
Inputs
- Outside mirror CAN-IHS auto dim request message from the BCM
- Command Ignition State
Outputs
- PWM signal to the exterior EC mirror
