1. Disconnect a negative wire from the battery. 2. Disconnect an electrical wiring from the sensor switch of disconnection of a chain of a starter. 3. Remove the sensor switch. 4. Check coupling pedal course size, in case of need make necessary adjustment (see the Section Removal, service, installation and adjustment of a pedal of coupling).

5. Measure sensor switch plunger vystupaniye size in its extreme situation, - if the result differs from value of 2+1.5 mm, replace the sensor switch. |
6. Check conductivity between its plugs No. 1 and No. 2 of the disconnected sensor switch. At the released coupling pedal the result of measurement has to make more than 1 megohm, at squeezed out, - less than 1 Ohm. 7. The faulty sensor switch is subject to replacement. |
