Examination
1. We install the car on a viewing hole or overpass (see "Vehicle preparation for maintenance and repair").
2. We clean the place of attachment of the switch and the switch itself from dirt.
3. Disconnect the wire blocks from the switch terminals.
4. Engage reverse gear. Connect an ohmmeter to the switch terminals.
Removing
1. With a 27 mm spanner, unscrew the switch.
2. Remove the switch. The connection between the switch and the gearbox is sealed with a copper washer.
Installation
1. Replace the sealing washer.
2. Installation of the switch is carried out in the reverse order.
3. After connecting the wires to the switch terminals, apply grease to them to protect them from water and dirt.
If the resistance tends to infinity, the switch is faulty.
