Checks control ignition and injection

1. The components of the control system is very reliable. Faults are usually associated with the unreliability or pollution of contacts. Breakdowns high-voltage wires usually occur due to contamination, humidity or damage of isolation, and not because of malfunction of a component of the system. Before you conclude a malfunction of any component, check the wiring.
2. Check the operation of high-voltage wires, removing it with a candle and approached the surface of the engine (watching for the presence of spark), you can not. You risk not only get an electric shock, and damage the control unit or the ignition coil. If the engine is unstable, never remove the tips of the wires from candles to determine the fault.
3. The following checks should be performed if the fault is obvious (the refusal starter, misfiring, and others.). Some faults are less obvious and can not be shown due to the fact that the engine management system has switched to emergency mode, ignoring the signals of the individual sensors and uses. Such faults are manifested in increased fuel consumption, idle speed instability, loss of power, knock, etc. If you notice these symptoms, contact the service station.

1. If the engine does not turn when the starter or rotates very slowly, check the starter and the battery. Connect a voltmeter to the battery terminals and measure the voltage while cranking the engine crankshaft starter. Do not operate the starter more than 10 seconds. If the voltmeter shows 9.5 volts and less sure of serviceability of the battery, starter and charging system.
2. When you turn on the starter motor runs at normal speed, but does not run, check all high-voltage ignition system components.
3. Follow the manufacturer's instructions, connect the stroboscope and crank the engine starter. If the lamp lights up on the stroboscope, the voltage supplied to the spark plugs. Ensure serviceability of candles. If the lamp does not light, check the high-voltage wires (refer to Section Check and replacement of spark plugs. Check the status of high-voltage wires).
4. If there is no spark, check serviceability of the ignition coil (or replace the coil with a known good or check the winding resistance). If no problem is found, look for it elsewhere. If you replace the coil engine began to run - a fault is detected. Do not rush to throw away and buy a new coil. Ensure the reliability of the wiring connection to the coil (the engine can not be started due to oxidised).
5. If the coil is in order, defective, perhaps, a powerful buffer output stage, which is an integral part of the engine control unit, one of the sensors of the engine control unit or collateral. In this case, the control unit should be recorded fault code that can be read from memory.
6. Fault codes can be read using special equipment.

1. The cause of the misfire is often unreliable contact wires to the terminals of the ignition coil or a sensor.
2. Turn off the ignition and check the reliability of connection of all connectors of the ignition system.
3. Check the high-voltage wires. Make sure that they are securely fastened at points intermediate brackets and not in contact with the metal parts of the engine. If the wire touches the metal and insulation has been damaged, the spark when the engine will be filed in a candle, and on the ground. If you notice even slight damage to the insulation of at least one wire, replace the entire set.
4. Make sure the wires can be fully operational, temporarily replacing them with known good.
5. When replacing the wiring change them one by one. This way you will avoid the risk of incorrect wiring. Do not damage the wires during installation.
6. If high-voltage wires fully operational, the cause of the misfire is likely ignition coil or any spark plug. Install a new set of candles (Refer to Replacing the cabin air filter / charcoal filter air cleaning) or check the coil. The cause of the misfire may be faulty, or the crankshaft position sensor is dirty.
7. If the test above sites has not led to an improvement of the engine, read the DTCs from the memory of the control unit (refer to spark plugs).
