Hi again - I tried to read the rollbar codes (pins 1 to 7) with a led volt meter last weekend but was unsuccessful. I need a more detailed discription of this proceedure and a list of the codes at this location. IE: do you short 1 and 7 for the same times as 1 and 10 to start (2 to 4 seconds) the codes and then clear (6 to 8 seconds) the codes?
Thanks, Craig
