System reaction to a fault
- Fuel shut-off
- Knock detection takes place in parallel on cylinders 1+4 and cylinders 2+3.
NOTE:
If there is a short circuit on any of the two combustion signals to ground, synchronization will not be performed and there will be no diagnostic trouble codes generated for the specific fault. A diagnostic code for misfiring will be generated instead.
Misfiring
- Emission-related misfiring will generate diagnostic trouble code P0300-P0304.
- If catalyst damaging misfiring occurs, diagnostic trouble code P1300-P1304 will be generated. CHECK ENGINE will flash during the misfiring.
- If catalyst damaging misfiring occurs in conjunction with a fuel level below 4 liters, diagnostic trouble code P1390-P1394 will be generated. CHECK ENGINE will flash during the misfiring.
- Closed loop is blocked at high engine loads.NOTE: To ensure optimal engine performance, the correct ignition discharge module must be used. Red ignition discharge modules must not be used.
