Applies to the following models:
2 modelsS80 (2007–), V70 (2008–)
Show models by year and engine (2)
What does this fault code mean?
The ADM keeps watch on the sensor that reads the tank level. The reference signal from the sensor has been registered as incorrect or implausible, and the code. The sensor is built into the additive tank and cannot be replaced separately.
Possible causes
- Poor contact, resistance or corrosion at the terminals
- Break in the signal wire, or a short to ground or to supply voltage
- Damaged additive level sensor
- Damaged additive dosing module (ADM)
What you can do
- 1Check the connector at the additive tank for looseness, resistance and corrosion
- 2Clear the code and check whether it returns
- 3If the fault returns with no visible cause, the additive tank may need replacing because the sensor is built into it
- 4After the repair, check that the code does not come back
