bobkathfl Report post Posted June 18, 2012 We purchased this MH in 2008. National Tradewinds Freightliner chassis and a Cat 3126 300 HP. The odometer registered but when the ignition was turned off it reset to 9596. The trip worked fine and that is how I keep track of miles for all maintance and fuel economy. Recently the trip odometer locked up, it could be reset but stayed at 0 but after a short stoppage it worked again. This whole scenario repeated and included the speedometer. The last time I drove it all worked. Any ideas Thanks Bob Share this post Link to post Share on other sites
wolfe10 Report post Posted June 18, 2012 Bob, Contact Freightliner in Gaffney, SC. This is a reasonably well known issue. Freightliner: 800 385-4357 need VIN Share this post Link to post Share on other sites
bobkathfl Report post Posted June 19, 2012 Brett: Thanks for the lead, Gaffney stated the problem is in a module that needs to be replaced at an estimated cost of $12 -15k. I am going to find and install a GPS driven speedometer odometer. Bob Share this post Link to post Share on other sites
dickandlois Report post Posted July 22, 2012 Sounds like a good plan !! Missed reading this thread earlier. One could get a scanguageD for diesels with both a 9 pin and 6 pin connector on it from camping world. That should read out your millage from the ECM and road speed; plus some other good information. Not bad for around $160.00 Rich. Share this post Link to post Share on other sites
desertdeals69 Report post Posted July 22, 2012 I've been testing a ScanGaugeD and it works very well. Also gives a lot of other data, MPG, MPH, Oil Pressure, engine temp, etc. A lot less expensive than a Road Relay from Cummins. Share this post Link to post Share on other sites
