Toyota Headlight System Malfunction

In February of this year, Toyota issued a recall for certain Toyota and Lexus models due to a headlight system malfunction.

However, some common symptoms may include the headlights flickering or going out entirely, the headlight bulbs burning out prematurely, or the headlight system not working at all

If you notice your headlights flickering or going out entirely, it’s likely that there is a problem with your headlight system. There are a few different things that could be causing the problem, so it’s important to troubleshoot and find the root cause. One possible cause of flickering or non-working headlights is a loose connection.

This can be between the headlight bulb and the socket, or between the wires that connect the headlight system to the battery.

You can check the voltage with a multimeter to see if it is within the normal range. If it is not, then you’ll need to have the electrical system repaired. If your headlight system is not working at all, it could be due to a blown fuse.

The fuse protects the headlight system from damage, so if it is blown, the system will not work. You can check the fuse by removing it and testing it with a multimeter. If it is blown, you’ll need to replace it with a new one.
