S80: Electrical Collision Warning System Service Required

[mantee78]

Hi. I've got this message on, checked for faults and it's:

FSM-U300066 Control Module. Algorithm Based Failrures. Signal has to many transitions/events.

The cruise control works fine, slows down when close to the car in front of me and speeds up ok, changes speed by +/- buttons as well. However no warning lights when too close to the car, just braking.

Is it radar unit behind the grill what is faulty or can be something else?

Thanks

Sorted it myself, I couldn't clear that code, as related code from brake system after replacing faulty abs sensor was not cleared out. Cleared all codes, took for a drive, engaged involved systems to allow reading all datas and no faults found, all system works now with no problems.

Hi i have the same warning on after my alternator repair...the voltage regulator was changed...the system was overcharging when all the lights went on....now the car works fine only one warning remained on...its the same "Collision Warning System Service Required"....with the diagnostics we had in the shop it shows everything is fine doesent show any codes...the cruise control works fine....never checked if the radar works...anyway my next thoughts are to go and see a shop who has a better computer...i really really hope the module aint broken or something...
