Suspension Module (SUM)
Volvo models this fault code applies to
Applies to the following models:
7 modelsS60 (2011–), S80 (2007–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
What does this fault code mean?
The suspension control module (SUM) works out the temperature of the right rear damper solenoid using its resistance. If the temperature becomes too high the fault code is stored and Four-C is limited.
Possible causes
- Contact resistance or oxidation in the connectors
- Hard driving
- Damaged solenoid
What you can do
- 1Avoid driving hard for long periods, as this heats up the damper solenoid
- 2Check that the connector at the right rear damper is firmly seated and not oxidised
- 3Read the fault status after a test drive to see whether the fault remains
- 4If the fault remains: have a workshop measure the solenoid resistance and replace the solenoid if needed
Symptoms you may notice1
- No noticeable symptoms for the driver
What the fault can affect1
- Four-C function is limited
