Applies to the following models:
9 modelsS60 (2011–), S80 (2007–), V40 (2013–), V40 Cross Country (2013–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
What does this fault code mean?
The IAM unit has registered that the gyro, which senses the car's rotational movement, gives values that do not match how the car is moving. The code is also set when the supply voltage is too high. Navigation can then be inaccurate or slow to update.
Possible causes
- Damaged integrated audio module (IAM)
What you can do
- 1Check that the fuses for the navigation are intact
- 2Try the navigation functions with the buttons and controls and note whether the position goes wrong when the car turns
- 3If you have diagnostic equipment: read the gyro value in live data with the car standing still and check that it is steady, and that it changes when the car turns
- 4Have a workshop check the module and replace it if the fault remains
- 5After the work, clear the fault code and check that navigation works
Symptoms you may notice3
- Navigation does not work
- The navigation system gives the wrong direction
- Information updates are slow or do not work
