| Fault Code Description |
|---|
|
The fault code is set when the system deviation of the smooth-running controller of at least one cylinder exceeds the maximum value (between 4.9 mg and 5.9 mg) dependent on the injection quantity. |
| Fault Code Conditions | |
|---|---|
| General Conditions |
The fault check takes place when smooth-running control is active. Control unit voltage: 9.5 V to 16 V. |
| Terminal Condition |

|
The fault is entered if it is present for longer than the following period (debounce time): 15000 ms |
| Service Plan |
|---|
|
1. Check retaining clips of fuel injectors. 2. Check intake ports and intake valves for sooting (excessive oil loss from crankcase ventilation system can cause sooting, especially when predominantly driving short distances). 3. Check compression, if compression is OK: Perform smooth running measurement, replace affected injector. |
