DTC 006

DTC 006

CIRCUIT DESCRIPTION
The body control module (BCM) flashes the headlamps and pulses the horns when a theft attempt is detected. The BCM grounds the headlamp and parklamp control circuits via a discrete input of the daytime running lamps (DRL) control module. The DRL control module actuates the headlamp and parklamp relays internal to the DRL control module.
