We have a 2014 Freightliner (M2, I believe) with an Allison transmission that is throwing random codes. First it seems to be shutting down due to the module that controls the windshield wipers. Next it says it's a sensor on the end of the emissions/DEF junk. Now it says it's an injector. I'm concerned it's the computer that is screwed up. We don't have the money to throw thousands of dollars at a problem that doesn't exist. How would you check the computer?
