Outputs
Range: ON/ OFF
The DRL relay output refers to the commanded state of the DRL relay coil.
ON displays when the BCM commands the DRL relay coil to turn ON. This allows the relay to power up the daytime running lamps.
OFF displays when the BCM does not command the DRL relay coil to turn ON. This denies current to the DRL relay coil and causes the daytime
running lamps to be OFF.
