Diagnostic Aids
The daytime running lamp (DRL) system will not work if the parking brake is applied. The system is designed to work only
when the engine is running and the parking brake is released. If the parking brake circuit is shorted to ground or the switch
stays closed when the engine is running, the DRL system will not work.
