Examination
1. First of all, check the condition of fuse No. 19 at 7.5 A in the mounting block located under the instrument panel.
2. Select reverse gear with the shift lever and turn on the ignition - the white reverse signal lights should light up. Switch off the ignition.
3. If the lights do not turn on, check the correct bulbs in the rear combination lamp assemblies.
4. If the fuse and lamps are in order, look for the reversing light switch at the top of the manual transmission case (see accompanying illustration), walk back along the wiring to the connector, disconnect the latter and connect an ohmmeter between the two exposed contacts.
5. When the reverse gear is engaged, conduction must take place between the connector pins (sensor-switch closed). In any other position of the lever, the sensor-switch must be open (no conductivity).
6. At negative results of the carried-out check replace the gauge switch.
7. If the switch is in order, check the power supply to it. If there is no voltage, check for an open in the wiring in the section of the circuit between the sensor-switch and the fuse mounting block. If power is applied, check the circuit between the sensor switch and the rear combination lamps.
Replacement
1. Disconnect the electrical wiring from the sensor-switch.
2. Turn out the gauge switch from a case of transmission.
3. Remove and discard the old washer.
4. Replace the washer and install a new switch sensor.
5. Connect electrical wiring.
