Table of diagnostics of a control system of a full drive
Before to carry out diagnostics of malfunctions, check, that transfer and forward differential were in good repair, and there was no leakage of air from air hoses and the actuator. Leakage of air is described in this section in the Section Service out of a workshop.

Notes on verification of the electroscheme of system:
- Before to start verification of the electroscheme, read Precautionary measures at service of electric chains in Chapter 0A and follow the recommendations stated there.
- The system electroscheme see in drawing in the Section the General description in this Chapter.
- The sequence of contacts is described in this Chapter, in the Section Verification of the electroscheme of management by a full drive.

|
|
1
|
Turn on the ignition switch (but the engine is stopped) and check malfunction of a bulb of the indicator.
The bulb burns?
|
Pass to a step 2
|
Somewhere there was a problem. Eliminate it
|
|
2
|
Check the electroscheme of the switch of a full drive.
Turn on the switch of ignition and check, that tension between contacts С51 - 2-18 and С51 - 3-17 ("earth") for G16/J20 was the following:
* When the gear shifting lever in situation N or 2Н: 10-14 Volts
* When the gear shifting lever in situation 4 L or 4Н: 0-1 Volt
Results of check are satisfactory?
|
Pass to a step 3
|
Check the switch of a full drive (see. Head Mechanical transmission (type 1)), electroschemes of "B/Or" and “B” of the switch of a full drive. If everything is all right, replace with the serviceable electronic control unit and recheck
|
|
3
|
Check a food.
Turn on the ignition switch.
Check tension between contacts С51 - 2-7 and С51 - 3-17 ("earth") for G16/J20. Results of check should be the following:
* When the gear shifting lever in situation N or 2Н: 0-1 Volt
* When the gear shifting lever in situation 4L or 4Н: 10-14 Volts
Results of check are satisfactory?
|
Pass to a step 4
|
Check “R” scheme. If everything is all right, replace with the serviceable electronic control unit and recheck
|
|
4
|
Check the electroscheme of the air pump.
Check correctness of connection with the air pump on all contacts.
Turn on the ignition switch.
Check tension between contacts С51 - 2-27 and С51 - 3-17 ("earth") for G16/J20. Results of check should be the following:
* When the gear shifting lever in situation N or 2Н: 0-1 Volt
* When the gear shifting lever in situation 4L or 4Н (more than 4 seconds after switching in 4L or 4Н): 10-14 Volts
Results of check are satisfactory?
|
Pass to a step 5
|
Check the air pump as it is described in the Section Service out of a workshop, and then “P” electroscheme. If everything is all right, replace with the serviceable electronic control unit and recheck
|
|
5
|
Check the electroscheme of a bulb of the indicator of a full drive.
Turn on the ignition switch.
Check tension between contacts E61-19 and С51 - 3-17 ("earth") for G16/J20. Results of check should be the following:
* When the gear shifting lever in situation N or 2Н: 10-14 Volts
* When the gear shifting lever in situation 4L or 4Н: 0-1 Volt
Results of check are satisfactory?
|
Control system of a full drive in a good condition
|
Check “Or/B” scheme (including a bulb of the indicator and the complex counter). If everything is all right, replace with the serviceable electronic control unit and recheck
