Daytime Running Lamp Relay: Description and Operation
DESCRIPTION
Vehicles built for use in Canada are equipped with a Daytime Running Lamp (DRL) system. All the exterior lighting messages come from Steering
Column Control Module (SCCM) or left multi-function switch on Local Interconnect Network (LIN) data bus and goes to the Cab Compartment Node
(CCN), then the CCN sends out a Controller Area Network (CAN) data bus message to the Totally Integrated Power Module (TIPM) for each lighting
function according to the request from left multi-function switch. Then the TIPM will turn ON/OFF the requested output. The DRL function is controlled
by TIPM. Daytime running lamps are High beam lamps at lower intensity.
