Daytime Running Lights (DRL) Telltale
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.
IMPORTANT:
Low resistance high beam bulbs or high charging system voltage can cause a flickering DRL telltale.
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.
