I was being driven mad by an intermittent fault in a parking aid module..... It works properly then does not and I get the solid bleep. I checked the sensors and the module all appeared ok so I purchased a new module fitted it and got a solid bleep again. Plugged in Autoenginuity diagnostics it says it needs to be calibrated? Not sure how? Any help please would be greatly appreciated.

Many thanks

I don't think it is calibratable...have you had someone wave their hand by each sensors? sounds like something is stuck in one of the sensors...does the beep go off after three seconds...if it does it is working properly...and it is probably one of the sensors...
