1. Electronic control unit
2. Sensor of provision of a butterfly valve
3. Switch
4. Alarm lamp of the switch
5. Switch of lamps of stoplights
6. The electromagnetic N2 valve of the switching lever
7. The electromagnetic N1 valve of the switching lever
8. Switch of system of blocking of ignition
9. The electromagnetic valve of the switching lever
10. Car speed sensor
11. Temperature sensor of cooling liquid

Elements of an electronic control system (6-cylinder engines)

1. System electronic control unit
control cruise
2. Electronic control unit
3. Sensor of provision of a butterfly valve
4. Switch
5. Alarm lamp of the switch
6. Switch of lamps of stoplights
7. Car speed sensor
8. Electromagnetic valve
the switching lever
9. The electromagnetic N1, N2 valve of the switching lever
10. Switch of system of blocking of ignition
11. The electromagnetic valve of the switching lever
12. Coupling speed sensor
13. Sensor of speed of rotation of a bent shaft
14. Temperature sensor of cooling liquid

Arrangement of the socket of the elektromaknitny valve (4-cylinder engines)

In 4-cylinder engines the socket of the electromagnetic valve is located in peredny speak rapidly transmissions, directly over the switch of system of blocking of ignition.

Arrangement of the socket of the elektromaknitny valve (6-cylinder engines)

In 6-cylinder engines the socket of the electromagnetic valve is located opposite to the switch of system of blocking of ignition.

Check of electromagnetic valves

1. Electromagnetic N1 and N2 valves

2. Compressed air

3. Accumulator

PERFORMANCE ORDER
1. To check electromagnetic valves, give accumulator tension on contacts of each of valves.
2. If valves are serviceable, you have to hear click.
3. Send a stream of compressed air to each of valves, pressure about 65 psi. Valves should not pass air.
4. Again give accumulator tension on contacts and be convinced that the valve opened.

CODES OF MALFUNCTIONS

The electronic control system is equipped with function of automatic search of malfunctions. The code of malfunction is brought in memory of system, and then highlighted on the display panel of a condition of the engine.
