I have a steering light on my vectra c. The power steering module has fault code U2139 invalid data from cim. The cim module has fault codes B1020 srs steering angle sensor signal cicuit range/performance. Also B1012 Steering angle sensor not calibrated. Tried calibrating angle sensor but faults still present. Does this mean i need a new cim.

What year is production date of your car? Possibly it's true and you have problem with sensor but this means you need TECH 2 and all accessories to make such replacement.
