What are the reasons for the Sagitar's daytime running lights not working?
3 Answers
The Sagitar's daytime running lights not working can be attributed to the following reasons: 1. The daytime running lights are turned off in the vehicle settings. 2. The daytime running light fuse is blown. 3. Wiring harness circuit failure. 4. The daytime running light bulb is damaged. 5. The headlight control module has water ingress. Solutions for daytime running lights not working are as follows: 1. If the driver accidentally turned off the daytime running lights in the vehicle settings, they can be turned back on by turning off the ignition, lifting the turn signal switch upwards, turning on the left turn signal, and holding it for three seconds. A beep sound will indicate that the daytime running lights are activated. 2. If the daytime running lights are not working due to a blown fuse, and one side is working while the other is not, the issue may not be the fuse but a wiring harness circuit problem. Check for loose connections or signs of water damage and corrosion inside the wiring. 3. If the daytime running lights are simply damaged, the bulb can be replaced directly. Typically, daytime running lights consist of LED diodes, and the issue might be due to a short circuit or aging of the diodes. As the resistance increases with temperature, the working current decreases, causing the daytime running lights to stop functioning. Water ingress into the headlight control module can also cause damage.
I was really worried when the daytime running lights on my Sagitar didn't work. Later, I found out there could be many reasons: burnt-out bulbs are the most common issue, as LED bulbs have a limited lifespan; blown fuses are also frequent, just replace the corresponding one in the fuse box; loose wiring connections or water ingress are quite probable, especially after car washing. There are also deeper issues like body control module failures, which might require computer diagnostics. I first checked the bulbs and fuses myself and solved the problem when I found a blown fuse. However, if it's a control unit issue, you'll need to visit the 4S shop, as it involves the control logic of the entire lighting system. Daytime running lights are crucial in rainy or foggy weather to enhance vehicle visibility, so it's best to get them checked and repaired as soon as possible if any issues are found.
Last time when my Sagitar's daytime running lights weren't working, the mechanic taught me several self-check methods: First check the fuse box located under the dashboard on the driver's side, identify the corresponding fuse and check if it's blown; then inspect whether the bulb is blackened or burnt out - if LED beads are damaged, the entire unit needs replacement. Another common cause is poor contact at wiring connectors, especially for vehicles frequently driven on muddy roads where plugs are prone to corrosion. The most troublesome issue is control module failure, which requires professional diagnostic equipment to read trouble codes. It's recommended to check the simple components first; if both fuses and bulbs are fine, take the car to the shop promptly. Remember, driving without daytime running lights in rainy weather reduces vehicle visibility by about 30%, posing safety risks.
