Daytime Running Lamps (DRL)
The daytime running lamps (DRL) telltale is turned ON by the cluster when it receives a command from the body control module (BCM). The telltale will be ON whenever DRL is in operation.
NOTE:
Low resistance high beam bulbs or high charging system voltage can cause a flickering DRL telltale in Cautions and Notices.
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.
