What is the reason for no signal in the left headlight power module?
1 Answers
Left headlight power module no signal reason is that the power module itself is not damaged, the fault is caused by an overload in the system's internal power supply. Below are the specific reasons and solutions: System internal power overload: The fault reason belongs to the system internal power overload. At this time, you can remove each component module of the system one by one to further check and determine the fault range. If after removing the power module, there is no +5V output or still only a few seconds of +5V voltage output, it indicates that the power module itself has an overload or internal component damage. Pull out the power module: During maintenance, you can pull out the power module to disconnect it from the load, then power on normally by connecting NC-ON. If the +5V voltage output is normal under this condition and the power normal signal output contact is closed, it proves that the power module itself is working normally.
