3.1.4.4.6. Check of elements of system EES IV
THE GENERAL DATA

For check of elements of system it is necessary to disconnect a multicontact socket from electronic actuation device EES IV, and then to execute corresponding measurements on contacts of this socket.

In case of detection of malfunctions it is necessary to check up first of all electric wires and their connections, and then to check up a corresponding element.

CHECK AND IDLING ADJUSTMENT

Entry conditions

The engine should be heated-up to normal working temperature. For this purpose it is necessary to increase its number of turns to 2000 rpm and to wait for opening of the valve of the thermostat. It is not necessary to warm up the engine idling as at long work in these conditions the maintenance WITH in exhaust gases will differ from the maintenance WITH at usual service conditions of the car.

The air filter should be established, and its replaced element should not be too polluted.

The ignition system should be in a good technical condition.

The additional air arriving through негерметичности of connections should not get to inlet system of the engine, damaged vacuum the pipeline etc.

The final system of the engine should be tight.

Any of electric power consumers (a lamp of headlights, the fan engine, heating of back glass, etc.) should not be included.

Check of number of turns

The number of turns of idling in the engines equipped with system EES IV, is regulated by electronic actuation device EES IV and possibility of manual regulation is absent. For engine DOHC of type N9A the number of turns of idling should make 87525 rpm.

Adjustment of the maintenance WITH


PERFORMANCE ORDER
1. To connect the analyzer of exhaust gases.
2. To check up the maintenance WITH idling which for engine DOHC of type N9A should make 1,0–1,5 %.
3. In case of need to adjust the maintenance WITH idling by means of a potentiometer of adjustment of the maintenance WITH.
