| CHECK TO BE PERFORMED | RESOLUTION IF THE CHECK IS NOT OK |
|---|
| 1 | Connect the diagnostic equipment and check that none of the following errors is present: P0300, P0301, P0302, P0303, P0304, P0305, P0306 | Continue as described by the diagnostic equipment |
| 2 | Start up the engine and let it warm up. Keep the engine at a speed of 2000 rpm and check that there is no misfire.The test can be considered over | Move on to Step 3 |
| 3 | Check that the errors have been detected at all the cylinders in one bank (P0301, P0302 and P0303 or P0304, P0305 and P0306 respectively).Move on to Step 10 | Move on to Step 4 |
| 4 | Press the START/STOP button (engine off).Disconnect the corresponding cylinder coil.Press the START/STOP button (panel on).Measure the voltage between Pin 2 of the coil See A030 IGNITION COIL and the Earth, checking that it corresponds to the battery voltage | Move on to Step 8 |
| 5 | Measure the voltage between Pins 2 and 3 of the coil See A030 IGNITION COIL checking that it corresponds to the battery voltage | Restore or, if necessary, replace the electrical wiring See E5030 PETROL ENGINES ELECTRONIC MANAGEMENT Move on to Step 11 |
| 6 | Measure the voltage between Pins 2 and 4 of the coil See A030 IGNITION COIL checking that it corresponds to the battery voltage | Restore or, if necessary, replace the electrical wiring See E5030 PETROL ENGINES ELECTRONIC MANAGEMENT Move on to Step 11 |
| 7 | If faults are present, repair or if necessary replace the ignition coil electrical wiring. See E5030 PETROL ENGINES ELECTRONIC MANAGEMENT Move on to Step 11 | Replace the faulty ignition coil Op. 5510C14 IGNITION COIL/S - R.R. Move on to Step 11 |
| 8 | Check that none of the components connected to the same line as the coil has faults in the electrical connections such as short circuits or poor insulation See E5030 PETROL ENGINES ELECTRONIC MANAGEMENT | Restore or, if necessary, replace the electrical wiring See E5030 PETROL ENGINES ELECTRONIC MANAGEMENT Move on to Step 11 |
| 9 | Replace the coil protective fuse See E5030 PETROL ENGINES ELECTRONIC MANAGEMENT Move on to Step 11 | |
| 10 | If faults are present, repair or if necessary replace the ignition coil electrical wiring. See E5030 PETROL ENGINES ELECTRONIC MANAGEMENT | |
| 11 | Reconnect all the electrical components disconnected previously. Using the diagnostic equipment, delete the errors in the engine management control unit. Start the engine and check that there are no longer any errors | Continue as described by the diagnostic equipment |
