Re: Throwing codes
I apologize for not seeing your post earlier. For you, and for anyone else who comes across this thread, here is the deal.
"Essentially when reporting troublecodes all the vehicles modules should stay quiet if they have no troublecode information, however we’ve found that there are instances where a module without any troublecodes will simply send out a response with ‘filler’ data that doesn’t have any meaning. The ScanGauge see’s this filler data, and tries to interpret it as a troublecode because anything that is reported should be actual troublecode data and not random filler data. Since discovering that sometimes this filler data is being broadcast alongside actual troublecode information we’ve implemented a filter in the Scan feature that will help screen out some of these garbage data messages.
Your best option right now is to send the 03 command and see what comes up. Since it seems that multiple modules are responding and since the command feature only captures whichever signal comes in first, send the 03 command a few times to see if you can get all the response messages. It’s somewhat random chance as to which responses arrive first, so sending the 03 command multiple times will raise your odds of seeing all the code data being sent by each ECU module."
Following those instructions, write down each response that you get. You can then interpret the message using the format for your vehicle (i.e. CAN: 4 (response to a command) X (the module responding) and 03 (the command being responded to) followed by the message and checksum). Scan gauge tech support can also try to help you decipher the message. I would personally ask that anyone who uses this option, please post the message and the interpretation here, so that we do not flood them with the same question over and over. Their tech support department has been very helpful in developing X-gauges for our trucks, and working to collect data on normal values, and values needed to enhance our fuel milage. You can find these in my other posts on this site.
