Hello dear XC-Experts,
On an XC70 2007 D5 I do have an issue with the Rear parking system. The dash delivers the "Parking Sensor Maintenance" message.
The car throws the following error codes:
REM-4F45 Park Sensor 4. Wrong Signal.
REM-4F4A Parking Assist Module (PAM). Wrong Signal.
I deleted the errors and only the PAM error REM-4F4A came back. I exchanged all four parking sensors yet the module error remained.
I can scan and check the module. I checked the cable and this it seems fine and the module has 12V power.
Any suggestions?
Greetings!
