Operation CHARM: Car repair manuals for everyone.

Daytime Running Lamps (DRL)

The DRL On 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 On 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.
