DRL
The DRL feature is not a programmable parameter for this vehicle.
The DRL system utilizes the fog lamp assemblies.
The BCM monitors the ignition status, the headlamp switch and autolamp status.
When the transmission is in not in PARK, the PCM sends a message over the HS-CAN1 to the BCM indicating the transmission is not in PARK.
Based on the input, the BCM activates the DRL.
The BCM supplies a high current switched voltage to the fog lamp assemblies to supply the necessary current to operate the lamps.
The BCM also provides an Field Effect Transistor (FET) protection of the exterior lamps switched voltage and DRL output circuits. When an excessive current draw is detected, the BCM disables the affected circuit driver.
