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 gearshift lever and turn on the ignition – the white reverse signal lights should light up. Turn off the ignition.
3. If the lights do not turn on, check the condition of the corresponding bulbs in the rear combination light assemblies.
4. If the fuse and bulbs are OK, locate the reverse light switch sensor on the top of the manual transmission housing (see accompanying illustration), follow the wiring back to the connector, disconnect the latter and connect an ohmmeter between the two exposed contacts.
5. When the reverse gear is engaged, there should be conductivity between the connector contacts (sensor switch closed). In any other position of the lever, the sensor switch must be open (there is no conductivity).
6. If the results of the check are negative, replace the sensor switch.
7. If the switch is OK, check that the power supply to it is working properly. If there is no power, check for a break in the wiring between the sensor switch and the fuse box. If power is supplied, check the circuit between the sensor switch and the rear combination lamps.
Replacement
1. Disconnect the electrical wiring from the sensor switch.
2. Unscrew the sensor switch from the transmission housing.
3. Remove and discard the old washer.
4. Replace the washer and install a new sensor switch.
5. Connect the electrical wiring.
