What Causes Automatic Daytime Running Light Switching Failure?
1 Answers
Automatic daytime running light switching failure may be due to settings issues, a blown fuse, or potential faults in the vehicle's wiring harness. Below is an introduction to the methods for handling automatic daytime running light failures: 1. Handling setting-related failures: Turn off the daytime running lights in the vehicle settings. Simply rotate the headlight switch to the automatic position, and the automatic daytime running lights will turn the headlights on or off based on the ambient light brightness. 2. Blown fuse for daytime running lights: If the fuse is blown, typically both sides will not light up, requiring repair or replacement of the fuse. If only one side is not working, it is likely not a fuse issue. 3. Wiring harness fault: Inspect the wiring harness between the headlight control module and the daytime running lights. If the wiring harness is faulty, it needs to be replaced.
