collision detection risk system fault

Post by sirev86 »

Hello,
Today, out of the blue, I got this error for a DS7 eTense, 2020:
Collision detection risk system fault

Left the car for few hours, but the error is still there when starting the engine. The radar and camera are clean... I did not hit anything..

Warranty expired long ago, so before contacting local DS service, is anyone who had this issue?

PS: I still hope the issue will be gone tomorrow morning.

Unfortunately the slightest thing can upset these devices. If the radar is even slightly moved it will need recalibrating. The camera is slightly more forgiving, but again this can need recalibrating if the windscreen has been replaced. If it's unlikely to be any of these things then will need further diagnostics with Diagbox. There should be a fault code logged.

Hopefully the radar needs recalibrating, because I heard replacing the radar is quite expensive..

A diagnostic with an appropriate professional scanner (as cheaper DIY scanners can't always pick up later systems and constructor codes) should help give some indication of the fault.

Do you think is worth doing this procedure before checking with DS service if calibration is needed:

?

Thanks.

Well if you don't mind reinitialising your key fobs and and anti-pinch windows / roof if applicable, it won't do any harm, put it that way. :wink:
