How is the DRL relay controlled by the BCM?
How is the DRL relay controlled by the BCM?
The DRL relay is controlled by the BCM based on the input form the ambient light sensor via CKT 592. The relay supplies current to the lights through CKT 545 and ground through CKT 150 and ground G100.
How are the daytime running lamps ( DRL ) controlled?
The daytime running lamps (DRL) lights are controlled by the body control module (BCM) via the DRL relay when the headlamp and panel dimmer switch is the AUTO position. The relay is feed by the IGNE fuse when the ignition switch is in the run and crank position, (the coil side of the relay), and the DRL fuse which is hot at all times.
How does the DRL work in a car?
When the BCM energizes the DRL relay in daylight conditions, the current flow is to both DRL lamps and to ground G100. The body control module (BCM) monitors the signal circuit of the ambient light sensor in order to determine if the daytime running lights (DRL) or the auto headlights (AHL) should be turned ON in the AUTO mode.
How does the DRL relay on a G100 work?
The IGNE 10 A fuse in the engine wiring harness junction block supplies ignition positive voltage to the DRL relay coil. When the BCM energizes the DRL relay in daylight conditions, the current flow is to both DRL lamps and to ground G100.
