Could you post the Model and chassis the Coach is built on for the group . Could you offer some information on the Smart wheel? Speedometer, ABS and check engine light, seam to be an odd combination. ECM is linked to all the mentioned issue form my limited experience. Rich. Share this post Link to post Share on other sites
jleamont Report post Posted February 19, 2020 Rich, pretty common on newer equipment that is multiplexed. When one module is missing an input i.e. open ABS sensor the others see the fault and illuminate their lights as well. I just experienced a new truck with a malfunctioning AM/FM radio cause a breakdown! Most newer chassis get the speedometer signal from the ABS module, and most will not move with a wheel speed sensor or ABS malfunction. Share this post Link to post Share on other sites

dickandlois Report post Posted February 19, 2020 F 432347 This is a copy of the manual that covers How to use the message center to read The Fault Codes that might be stored. They keep trying to keep things up to date as the software changes. This file is 52 pages long. https://www.rvtechlibrary.com/chassis/spartan_message_center.pdf Check Page 23, Section 2-15 covers fault code retrieval. Might be a good starting point. The other item to check is the ground connections, because issues you did mention are intermittent. Rich. Edit, Added information . This is a less intensive PDF file that covers the coach gauges and message center. This file is 14 pages long. https://www.spartanchassis.com/cps/login/UploadedFiles/Medallion Gauges-Spartan Operators Guide _RevA 8-28-04__12820061424088530000.pdf Share this post Link to post Share on other sites
