How to Program TPMS Sensors with a Diagnostic Tool
Last Updated: March 2026 Tire Pressure Monitoring System (TPMS) sensors are a safety-critical component on every vehicle sold in the United States since 2008. When you replace tires, swap wheels for winter or summer sets, or when a TPMS sensor battery dies, you need to program and relearn the new sensors to your vehicle. This guide explains the complete TPMS sensor programming process using a ThinkCar TPMS tool, including the difference between cloning and programming, and how to perform the relearn procedure for all major vehicle brands. Understanding TPMS Sensor... Read more...
How to Do Throttle Body Relearn with an OBD2 Tool
Last Updated: March 2026 The throttle body relearn procedure — also called idle relearn, throttle position adaptation, or electronic throttle control (ETC) reset — is one of the most commonly needed service procedures on modern vehicles. After cleaning the throttle body, replacing it, or disconnecting the battery, the engine control module (ECM) loses its learned throttle position values. This results in rough idle, stalling, high idle speed, or a check engine light. A throttle body relearn with an OBD2 diagnostic scanner restores proper idle control in minutes. When Is a...

How to Perform DPF Regeneration with a Diagnostic Scanner
Last Updated: March 2026 If you drive a diesel-powered vehicle, the DPF (Diesel Particulate Filter) is one of the most important emissions components in your exhaust system. The DPF traps soot particles produced during combustion and periodically burns them off through a process called regeneration. When the DPF becomes too clogged for passive regeneration (which happens automatically during highway driving), a forced regeneration using a diagnostic scanner becomes necessary to prevent engine damage, reduced performance, and expensive DPF replacement. This guide explains the complete DPF regeneration procedure using a ThinkCar... Read more...
How to Reset Electronic Parking Brake (EPB) After Service
Last Updated: March 2026 The electronic parking brake (EPB) has replaced the traditional handbrake lever or foot pedal on most modern vehicles. While EPB systems are more convenient and reliable for daily use, they require a diagnostic scanner to properly service. After any brake work involving the rear calipers — pad replacement, rotor resurfacing, or caliper replacement — the EPB system must be reset to function correctly. This article explains the full EPB reset procedure and when it is needed. What Is an Electronic Parking Brake (EPB)? An electronic parking... Read more...
How to Do a Brake Pad Reset with a Scan Tool
Last Updated: March 2026 Replacing brake pads on a vehicle equipped with an electronic parking brake (EPB) or electric brake calipers requires more than just swapping pads. The brake caliper piston must be retracted electronically before you can remove the old pads, and the system must be reset after installing the new ones. Attempting to push the piston back manually on these systems can damage the electric motor inside the caliper, leading to a repair bill that far exceeds the cost of the brake pads themselves. A brake pad reset... Read more...
How to Reset Oil Service Light with an OBD2 Scanner
Last Updated: March 2026 If your dashboard is showing an oil change reminder or service light after you have already changed the oil, you need to reset the oil service light. Modern vehicles track oil life using algorithms that factor in mileage, engine temperature cycles, and driving conditions. After an oil change, the system must be manually reset to begin a new monitoring cycle. While some vehicles allow a manual reset through the instrument cluster buttons, many newer models require an OBD2 diagnostic scanner to properly clear the oil service... Read more...

ThinkCar vs Launch: Pro-Level Diagnostics at Half the Price?
TL;DR - ThinkCar vs Launch ThinkCar offers comparable or superior diagnostic features to Launch X-431 scanners at a lower total cost of ownership. Launch charges $399-$799/year for software updates after the initial free period (1-2 years depending on model). ThinkCar includes lifetime free updates on every product. Over 5 years, a ThinkCar Platinum S20 saves $1,596-$3,196 compared to a Launch X-431 PAD VII with similar features. Both brands are Chinese-manufactured with strong OEM partnerships, but ThinkCar's no-subscription model delivers significantly better value for most shops. Launch Technology (also known as...

ADAS Calibration: What It Is, Why It Matters, and How to Do It
Last Updated: March 2026 ADAS Calibration: What It Is, Why It Matters, and How to Do It Every year, more vehicles roll off the assembly line with cameras, radar sensors, and lidar units that actively intervene to prevent collisions. These Advanced Driver Assistance Systems — ADAS — are no longer exclusive to luxury vehicles. A base-model 2026 Toyota Corolla has automatic emergency braking, lane departure warning, and adaptive cruise control as standard equipment. A fully loaded pickup truck can have 12 or more ADAS sensors. Here is the problem: these... Read more...
CAN FD Protocol Explained: Why Your Next Scanner Needs It
Last Updated: March 2026 CAN FD Protocol Explained: Why Your Next Scanner Needs It If you have tried to scan a 2022 Ford Bronco, a 2023 Chevy Silverado, or a 2024 Toyota Tundra with an older diagnostic scanner and gotten nothing but communication errors, you have already run into the CAN FD problem. Your scanner is not broken. It is speaking a language the vehicle does not understand anymore. CAN FD — Controller Area Network with Flexible Data-rate — is the most significant change to vehicle communication protocols in over... Read more...
