Imagine this: You’re driving down a sunny California highway, windows down, music playing, when suddenly – beep, beep, beep – the dreaded TPMS light flashes on your dashboard. Your heart sinks. You know what it means: a tire pressure issue. But can your trusty OBD2 scanner, the one you use to diagnose engine trouble, actually help you reset the TPMS? Let’s find out.
Understanding the Question: OBD2 Scan Tools and TPMS
Before we dive into the answer, let’s break down what we’re dealing with here.
From a Mechanic’s Perspective: We often get asked if a simple OBD2 scan tool can handle TPMS resets. It’s understandable why car owners would think so; after all, the OBD2 port is like the car’s communication hub.
Technically Speaking: OBD2 scanners are designed to communicate with your car’s engine control unit (ECU) and retrieve diagnostic trouble codes (DTCs). These codes help pinpoint issues related to emissions, engine performance, and other related systems. TPMS, while important for safety and tire life, operates on a slightly different frequency.
The Economics of Car Repair: It’s natural to want a single tool to handle all your car troubles. It could potentially save you time and money at the mechanic. So, the desire for a do-it-all OBD2 scanner is completely valid!
Can You Reset TPMS with an OBD2 Scanner?
Here’s the deal: Most standard OBD2 scanners cannot reset your TPMS light. This is because:
- Different Systems: Think of TPMS and your engine control unit as two separate departments in a company. They have their own communication protocols.
- Specialized Tools: Just like you need specific tools for specific jobs, resetting TPMS often requires a dedicated TPMS relearn tool or a higher-end scanner with bi-directional capabilities.
However, there are exceptions! Some advanced OBD2 scan tools, particularly those designed for specific car brands like Autel or Launch, offer TPMS reset functions.

When a Standard OBD2 Scanner Might Help
While a basic OBD2 scanner might not reset your TPMS, it can still be helpful:
- Identifying the Issue: It might reveal if a faulty sensor is causing the TPMS light to come on.
- Clearing Codes: After adjusting your tire pressure, some basic scanners can clear the old DTCs related to TPMS.
How to Reset Your TPMS Light
Here are some common methods:
-
Manual Reset: Many cars have a manual reset button hidden somewhere in the glove compartment, under the steering wheel, or near the emergency brake. Check your owner’s manual for the exact location.
-
Driving Technique: Some vehicles automatically reset the TPMS after driving for a specific distance (usually 10-20 miles) at a certain speed.
-
TPMS Relearn Tool: These affordable tools, like the Autel TS408, communicate directly with the TPMS sensors to relearn their positions after a tire rotation or sensor replacement.
