What Does Resetting an OBD II Scanner Mean?
Before we dive into the “how-to,” let’s understand the “why.” Resetting your OBD II scanner essentially clears its memory, bringing it back to its default settings. Think of it like restarting your smartphone – a simple action that can resolve many minor glitches.
From a mechanic’s perspective, a reset can be crucial for ensuring accurate diagnostics. As John Miller, author of “Automotive Diagnostics: A Practical Approach,” puts it, “A cluttered scanner memory is like a cluttered toolbox – it makes finding the right tool for the job much harder.”
When and Why Reset Your OBD II Scanner
There are several situations when a reset can be the magic touch your scanner needs:
- Scanner malfunction: If your scanner is acting up, showing erroneous readings, or freezing, a reset might be the solution.
- After using the scanner on a different vehicle: Resetting the scanner before plugging it into another car helps prevent potential conflicts or inaccurate readings.
- Clearing old codes: Even after fixing a problem, the related error codes might remain stored in your scanner’s memory. Resetting it ensures you’re only seeing current issues.
How to Reset Your OBD II Scanner: A Step-by-Step Guide
While the exact process might vary slightly depending on the make and model of your scanner, the general steps are quite similar:
- Power on your scanner. Most scanners require you to turn them on before initiating a reset.
- Locate the reset button/option. This is often a dedicated button labeled “Reset,” but it could also be a menu option within the scanner’s interface.
- Initiate the reset. Press the reset button or navigate to the reset option and confirm your selection.
- Wait for confirmation. The scanner might take a few moments to complete the reset process. You’ll usually see a confirmation message on the screen.
Can’t Find the Reset Button?
Don’t fret! Some scanners might not have a dedicated reset button. In this case, refer to your scanner’s user manual for specific reset instructions.
