MIRROR TURN SIGNAL LAMPS
| Refer to COMPONENT INDEX . |
If the configuration of the vehicle includes side repeater lamps, the two front DCMs enable the mirror turn signals to be activated and also perform the diagnostics on the signal mirrors. When the BCM outputs that the left or right turn signal state is ON and the right or left indicator is ON, the appropriate DCM mirrors the BCMs signal blinking rate by use of a hardwired signal.
If the vehicle is equipped with mirror running lights, the BCM sets the output signal to the DCM to activate.
