How do I reset my OBD2 scanner after a software update?
Quote from CarGuyBrad on June 17, 2025, 2:44 pmI recently updated my OBD2 scanner’s software, and after that, it's acting a bit strange. Some functions aren’t working properly, and a few error messages are popping up. I’m wondering if I need to reset the scanner to apply the update correctly. What is the proper way to reset an OBD2 scanner after updating the software? I’m using a Launch CRP129E but I think general advice would help for most OBD2 scanners.

Their support advised me to not only reset through the system menu but also clear the cache and perform a full reboot. After doing that, everything worked smoothly and the new software features were active.

Some models may also have a “Factory Reset” or “Settings Reset” option in the menu—check your user manual for exact steps.

Quote from CheckEngineChamp on June 19, 2025, 11:08 amAfter a software update, most OBD2 scanners need a simple reset. Just power off the scanner, unplug it from the car, and reconnect it after 1–2 minutes. If it has a built-in battery, hold the power button for a hard reset or check the user manual for a factory reset option.
