Checking for voltage
1. Disconnect Hall sensor plug (on the ignition distributor).
2. Connect a voltmeter to the outer contacts.
3. Turn on the ignition.
4. Required value: at least 10 V. Otherwise, the control device is faulty.
5. Switch off the ignition.
Checking work
1. Disconnect the plug of the cold start valve and the multi-pin plug of the injection valves.
2. Remove the rubber plug from the Hall sensor and disconnect the sensor plug.
3. Connect the LED indicator to the middle and outer wires of the Hall sensor plug.
Attention! During this test, do not touch the connected parts of the transformer and the indicator wires with your hand.
4. Turn on starter.
5. The LED must flash, otherwise the Hall sensor is faulty. In this case, for a 4-cylinder engine, replace the ignition distributor, for a 5-cylinder engine, disassemble the ignition distributor and replace the Hall sensor.
6. Connect the cold start valve plug and injection valve multi-pin connection.
