Co oznacza ten kod błędu?
The ADM compares the power supply to its own module with what the CEM reports. This code is only relevant if it has been active for a long time in the same driving cycle and you notice a loss of function that can be linked to it. Otherwise it does not indicate a fault and can be cleared.
Możliwe przyczyny
- Poor contact, resistance or corrosion at the terminals
- Open circuit in the power supply
- Power supply shorted to ground
- Damaged additive dosing module (ADM)
Co możesz zrobić
- 1Check whether the engine control module has stored codes for communication with the ADM; if not, the code can be cleared without further action
- 2Check the power supply and ground connection to the ADM and that the connectors are secure
- 3Check that the battery and its terminals are in good condition
- 4If the fault persists together with a loss of function, have a workshop trace the supply and the module
Objawy, które możesz zauważyć1
- No clear symptoms for the driver
