9.1.5. Check and replacement of the sensor switch of fires of a backing
Check
PERFORMANCE ORDER
1. First of all check a condition of a safety lock No. 19 on 7.5 A in the assembly block located under the dashboard.
2. Choose as the switching lever the reverse gear and include ignition – white signal lights of a backing have to light up. Switch off ignition. 3. If fires do not join, check serviceability of the corresponding lamps in assemblies of the back combined lamps.
4. If a safety lock and lamps as it should be, find the sensor switch of fires of a backing in the top part of a case of RKPP (see an accompanying illustration), walk on an electrical wiring to the socket back, disunite the last and connect an ohmmeter between two bared contacts.
5. At the switched-on reverse gear between contacts of the socket conductivity has to take place (the sensor switch is closed). In any other position of the lever the sensor switch has to be opened (there is no conductivity). 6. At negative results of the carried-out inspection replace the sensor switch.
7. If the switch as it should be, check serviceability of giving of food for it. In the absence of tension check for break an electrical wiring on the site of a chain between the sensor switch and the assembly block of safety locks. If food moves, check the site of a chain between the sensor switch and the back combined lamps.
