Sunroof / Moonroof Relay: Description and Operation

SUNROOF RELAY

The BCM has a discrete output used for the control of the Sunroof relay. In the RAP power mode the BCM will supply a B+ to the control circuit to enable the relay. The BCM also enables the relay in the Accessory and Run power modes. Refer to Retained Accessory Power (RAP) Schematics to become familiar with the system and for the circuit identification.
