Position 4L: INCL.

Signal OFF/INCL. how it is described above?

Without the aid of scanning tool SUZUKI:

Uncover the electronic block of management (РСМ)

Include the ignition switch

Check up pressure on contact C 51-1-26 for G16/J20 a socket of the electronic block of the management which is becoming isolated at switching of the lever of transfer to each position

Position 4Н or 2Н: 10-14 Volt

Position 4L: 0-1 Volt

Pressure such how it is specified?

Check up quality of connection on contact of the electronic block of management if in a step 2 the voltmeter is used

If connection is perfectly in order, a problem of intermittence of a chain or the faulty electronic block of management. Check up on intermittence as Interrupting or weak connection is described in the Head the General information in Section
