Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
System Description: Notes
Daytime light system turns ON daytime light lamps while driving. Daytime light lamps are not turned ON if engine is activated with parking brake ON. Release parking brake to turn ON daytime light lamps. The lamps turn OFF when the lighting switch is in the 2ND position or AUTO position (headlamp is ON) and when the lighting switch is in the PASSING position (daytime light lamps are not turned OFF only by parking brake itself).
The parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN communication line, and control daytime light system.
