I am trying to get the rear parking aid on my recently purchased 2007 STR to work. I can hear a beep for a few seconds when I go into reverse which I understand is evidence that there is something wrong, but none of the four sensors work or click when I go close. My OBD scanner has identified three faults in the Parking Aid Module including (a) C1170 Rear right center sensor fault, (b) B1299 Power supply sensor – circuit short to ground, and (c) B2477 Control module configuration failure. Any thoughts on how I could fix this would be gratefully received; for instance, is changing the faulty sensor likely to sort out the problem or is the module also likely to be faulty?
While rummaging around in the boot, I found two leads which I have labelled Plug A (on the left) and plug B (on the right) coming off the wire harness which goes across the back of the boot. Neither are plugged in anywhere, and in fact I cannot find anywhere nearby for them to be plugged into. Does anyone know what these two wires are for? Do all S-Types have them and they are meant to be connections for options which my car does not have? Again, any thoughts would be most welcome.
