The reverse light switch can be removed from the top of the engine compartment.
We clean the reverse light switch and the part of the gearbox housing around the switch from dirt.
We carry out the work with the ignition off.
The switch is located in the gearbox housing, at the front of the vehicle.
After pressing the block lock, we disconnect the block of wires from the switch.
After turning on the ignition, we close the contacts of the switch wiring block with a piece of wire.
If the reversing light does not come on, the electrical circuit should be checked.
Otherwise, it is necessary to replace the switch with a new one.
Using a 19 mm wrench, unscrew the switch.
We remove the switch from the hole in the gearbox housing.
The switch is sealed in the crankcase with a metal ring.
We connect the tester probes to the switch terminals and test the switch in the "ohmmeter" mode.
For a serviceable switch, when its rod is in a free state, the tester should record "infinity", and when the rod is "recessed", (the switch contacts are closed) - the presence of a chain.
We install the reversing light switch in the reverse order.
We tighten the switch to the prescribed torque.
