Haven't been here for a while. I read the post and thanks for the input. However, is there a windows based software that would reprogram/flash the ecu, ecm, pcm (ENGINE COMPUTER) and the srs module? Its just taking me a little longer than it should to really determine if a ecu is the fault..at least by flashing or reprograming an ecu should let me know its kosher. I know about can management and all but just trying to see a different approach in cutting on downtime. Thank you.
