Default Focus LS 2006 Reverse Sensors on Cold Start

Hi Everyone,

I'm having some issues with morning starts and cold starts.

When the car is put into reverse during a cold start, the rear sensor (I believe) gives an obnoxious loud beep. I can intermittently hear the rear sensors independently beeping through. I don't know if its an error code as my driveway takes about 15 seconds to drive down.

I've tried listening to the 'ticking' noise that generally comes from the sensors, but I cannot hear anything from any of the sensors (Ignition II and in R).

I'm speculating it a voltage issue with the Park Assist Module, anyone had any experience with this?

Cheers

I'd start by getting the diagnostic codes read - if it's the PAM then it will likely be throwing errors but it could be a faulty sensor which would also throw DTC's.
