3 modeleC30 (2007–2013), S40 (2004–2013), V50 (2004–2013)
Co oznacza ten kod błędu?
The engine control module (ECM) keeps watch over the ignition circuitry. The code is set when the signal from ignition coil 2, which feeds cylinders 2 and 3, reads too high. The most common cause is the primary wire touching a supply voltage, but a damaged coil can also trigger the fault.
Możliwe przyczyny
- Primary wire short-circuited to supply voltage
- Damaged ignition coil
Co możesz zrobić
- 1Read and clear the code, then road test to see whether it returns
- 2Check that the connector to ignition coil 2 is secure and free from corrosion
- 3Look for a pinched or chafed cable on the primary wire where it may have touched a live conductor
- 4If you have a diagnostic tool: check in live data whether the ignition coil 2 signal reads too high while the engine runs
- 5If the fault remains after these checks, have a workshop decide whether the coil should be replaced
