Mine just came up with 'unknown - please call' or something like that...but you go step by step with which lights are on, and what combination of lights they are..

So far (and it's only been a day) I am happy. It's almost weird to see my dash with no lights on it. And a HECK of a lot cheaper than a new one.

 

Just an update... I made my semi-annual trip from TX to TN and back at Christmas, had a couple of instances where my antilock brakes were useful on the Interstate... and they worked like a charm, still no lights, and no problems.

 

Wow this is very interesting...thanks for all the info about the prob could help someone greatly somewhere down the road
