Daytime Running Lamps (DRL)
The DRL telltale is turned On by the cluster when it receives a command from the BCM. The telltale will be On whenever DRL is in operation.The DRL telltale will turn Off if the High or low Beams headlamps are activated or if a High Beam Headlamp fails.
However, if both high beams fail, the DRL will turn On again. This is because the DRL circuitry is unable to identify this condition.
NOTE: Low resistance high beam bulbs or high charging system voltage can cause a flickering DRL telltale.
