Emissions tests in Ontario Canada

Post by HemiCrazy »

Hi Everyone, I am new to the forum and hoping someone might be able to help me. My 06 Durango Hemi recently decided to throw some codes and when I look them up it is the MDS codes 3401 and 3400 I believe. I have been troubleshooting the issue and all the solenoids sound like they are working. I can hook up a code reader and clear the codes, start the engine and drive, MDS will try but will not engage. No codes are thrown while driving. When I turn the vehicle off and turn the ignition back to on the codes are back. I have thought about a tear down but most of the driving I do in it is pulling a trailer so MDS is not used much which has led me to my question. If I get the intune or Trinity and turn active fuel management off will that keep the codes from being thrown and will it be detected by an emissions test? Emissions test in Ontario are now performed through the OBDII connector versus tailpipe.

Thanks for any guidance anyone can give.
