Does Autozone Test Ecm

If your car’s engine control module (ECM) is malfunctioning, you may be wondering if AutoZone offers ECM testing and whether or not it would be worth it to have the test done. To answer the first question, yes, AutoZone does test ECMs. However, they will only do so if the ECM is from a car that was manufactured in 1996 or later.

This is because all cars manufactured after 1996 are required to have on-board diagnostics (OBD II), which the AutoZone testing machine needs in order to properly test an ECM. As for whether or not it’s worth having an ECM tested at AutoZone, that really depends on the individual situation. If you have a feeling that your ECM is causing problems but you’re not quite sure, then it couldn’t hurt to get it checked out.

On the other hand, if you know for certain that your ECM is faulty and needs to be replaced, then there’s no need to waste time and money on a test that won’t provide any useful information.
