[2020] Xiao Jingrui replaces the reversing switch

September 25, 2024

Nothing is difficult in the world, as long as you are willing to climb.
Regarding Jing Rui, I adhere to the principle of being able to handle it myself and resolutely repairing it myself.
1. Symptoms:
1. The car is put in reverse gear, look at the rear of the car, and no reversing lights are on.
2. All equipment on the reversing lamp line that draws power cannot work normally.
My Iron General reversing radar and 360 driving recorder both need power supply from the reversing light group.
Every time I reversed and put it in reverse gear, there was no reaction.
At first, I thought the reversing light bulb was broken, so I went directly to the 4S store to check. Finally, I found out the reason. The reversing switch was broken.

It was easier to check if there was a problem. Since there were no ready-made parts in the store, I bought two online. After a week’s wait, the incoming goods can be installed directly.

The backup lamp switch is a normally open switch (normally open). When reverse gear is placed, the mechanical mechanism presses down the contact of the switch to close the circuit, the reverse gear light is on, and the reverse gear warning sound is sounded. When the reverse gear is disengaged, the switch contact pops up, and the reverse gear light circuit becomes disconnected again. Just like the household doorbell switch, hanging in the reverse push rod to press the switch down and connect the power supply is the same as holding down the doorbell switch with your finger.

After a long wait, it became important. Open and correct ~~~

Remove the lower guard first.

A disconnected reverse switch. They broke off in unison. It was probably because the copper wire was corroded and peeled off at the contact point. The following is the process of groping and disassembling. There is a small buckle on the left side. Press it inside and pull it out with great force.

Remove the switch.

Connect the new reversing switch to the broken cord. Because it is a switch, there is no difference between positive and negative, so just connect it boldly and make it waterproof.
