Hva betyr feilkoden?
The engine control module monitors the current drawn by the pump in the leak diagnostic unit during the reference phase. If the current varies too much during that phase, the fault code is set. The fault can come from poor contact, a blocked hose between the filter and the unit, or a damaged leak diagnostic unit.
Mulige årsaker
- Contact resistance in the connections
- Filter-to-unit hose is blocked
- Damaged leak diagnostic unit
Hva du kan gjøre
- 1Have a workshop confirm that the engine control module software is current on cars of model year 2003 to 2008
- 2Have you got a diagnostic tool: read the pump current in live data during the reference phase and check whether it swings a lot
- 3Check the connector to the leak diagnostic unit for contact resistance and oxidation
- 4Look for kinked or clogged lines running from the filter to the unit
- 5Run a new quick test after the repairs and check that it no longer shows a fault
- 6Have a workshop replace the leak diagnostic unit if the fault remains after these checks
Symptomer du kan merke1
- Malfunction indicator lamp (MIL) is on
Hva feilen kan påvirke1
- The leak diagnostic is disabled
