Hi all. My adaptive cruse control has just stopped working but everything else seems to work just fine, well apart from the yellow lines that are displayed when you select reverse do not turn with the steering wheel. I have checked fuses & all seem to be OK. I have also removed the parking module & taken it apart to look for signs of corrosion & that is OK. Does anyone know if the ACC is linked to the parking module? I do have on the dash the adaptive cruse control light continuously flashing.

On my IID tool I get these two codes;
U0159-00 (2A) Lost communication with parking assist control module.
U2003-86 (2 Fibre optic communication bus - bus signal/message failed - signal is invalid.

Any thoughts & input welcome, Cheers.

This could be a complete red herring but in relation to the fibre optic code there’s a thread elsewhere that suggests to try:

Cheers for that. But for some reason my car was not fitted with TPMS. I thought it was standard on all FFR but there are no sensors in the wheel arches. The wiring is there however but I can't find the module in the boot either. I know this as I was thinking of retro fitting it. 2010 RR Autobiography 5.0 SC

So it’s the other fault that relates to the ACC fault?
Also should the yellow lines with the reverse camera turn as you turn the steering wheel. Can anyone confirm this please. 👍🏻 2010 RR Autobiography 5.0 SC
