My wife's 03 Expedition' s back-up alarm is getting a 'check back-up alarm' message on the info. panel. It failed once before when it was in warranty and they replaced a 'module' (what module, I don't know) and it worked until it got out of warranty (just my luck). The service tech said that it was the radar module this time and it would cost about $680 to replace it. My questions are, where is this radar module? Can I troubleshoot it my self? If that is problem, can I buy one any cheaper from some other source?
Thank you in advance for your advice,
