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 integrated audio module (IAM) has detected that the signal from the antenna amplifier is missing or incorrect on the antenna cable for antenna number 2. The antenna cable is checked when the control module is switched off, and the fault is only recorded once the conditions are met. It most often shows up as poor radio reception, on both FM and AM.
Possible causes
- Open circuit or short circuit to supply voltage on the signal cable
What you can do
- 1Read the code, clear it and check whether it returns after a test drive
- 2Check that the fuses for the radio and antenna system are intact
- 3Check the connectors at the antenna amplifier and the audio module for loose or corroded contacts
- 4Use a multimeter to check that the signal cable is not broken and has no contact with the battery positive lead
- 5If the fault remains, have a workshop check the integrated audio module (IAM) with diagnostic equipment
Symptoms you may notice3
- Poor radio reception
- Weaker reception on the FM frequencies
- Weaker reception on the AM frequencies
