Applies to the following models:
5 modelsS60 (2001–2009), S80 (1999–2006), V70 (2000–2008), V70 XC / XC70 (2001–2007), XC90 (2003–)
What does this fault code mean?
The fault is intermittent: the power seat module (PSM) has on an earlier occasion registered a fault in the main relay or the power supply. The fault is not present now. The seat then does not function at all.
Possible causes
- Defective power seat module (PSM)
- No power supply to the motors
What you can do
- 1Check that passenger compartment fuses 4 and 24 are intact and sit firmly in their holders.
- 2If a fuse has blown, look for an intermittent short-circuit to ground in the wiring by moving the wires while measuring with a multimeter.
- 3Check that the connector to the control module is firmly seated and free from corrosion.
- 4Try to activate the seat motors. If none of them work, an internal relay in the control module may have stuck in the active position.
- 5If no faults are found, have a workshop replace the power seat module (PSM).
Symptoms you may notice1
