Hi Samantha, resetting the ECM is actually quite simple. You will need to disconnect the negative terminal of your battery for about 15 minutes, then reconnect it and turn on your vehicle. The ECM will be reset and any issues should be resolved.

Sam, when you reset the ECM, it will erase any diagnostic trouble codes (DTCs) that are currently stored in the system. This means that if there is an underlying issue causing your current problems, it will no longer be detectable.
