THE GENERAL DATA

The equipment of management of carburettor Ecotronic at failure of a probe of Ljambda works according to the emergency program. For the purpose of check of this function it is necessary to spend simulation of damage of a probe of Ljambda. Simultaneously it is necessary to observe functioning заслонки the start-up equipment, whether it functions normally.

PERFORMANCE ORDER

1) warm up the engine to temperature 60 ° With

2) remove the case of the air filter

3) remove from outside the carburettor the vacuum pipeline connecting a temperature regulator and the carburettor; the union densely закупорьте

4) start the engine and leave it idling

5) disunite a connecting wire of a probe of Ljambda, observing simultaneously of a diaphragm of the equipment of start-up. The emergency program of the equipment of start-up should cause diaphragm installation at an angle 60 ° - наискос. The emergency control module Otherwise can be damaged, a wire of a probe of Ljambda will close on weight or the regulator of a diaphragm of the equipment of start-up is damaged

6) if diaphragm position correct, it is necessary to close approximately for 20 seconds a green wire from a bunch feeding a probe of Ljambda (a wire to the management equipment) with weight. The diaphragm should slowly a few be covered. Otherwise it is necessary to check up, whether there are no damages of connecting wires, and if necessary to replace the management equipment
