    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?

    post all codes here. Must be in SPN xxxx Fail xx format. Your truck has many computer boxes. You Need DiagnosticLink software with vehicle interface cable-adaptor to check all computers.
