When the harness connector fails, the electronic components work intermittently.
一. Troubleshooting: 1. Check whether the appearance of the connector is damaged
2. Check whether the connector connection is loose
3. Check whether the inside of the connector is dirty
4. Check whether the connector pins are off
5. Check whether the connector pins are deformed
6. Check whether the resistance or voltage between the connector pins is within the normal range
二:Cause of failure:
1. Water enters the connector (caused by damaged housing or missing seals, etc.), resulting in pin oxidation or corrosion.
2. The connector is loose (caused by the deformation of the shell or internal reed, etc.), resulting in a virtual connection of the pins.
