LAUNCH X431

 The LAUNCH X431 diagnostic tool can clear vehicle body collision data. This article will demonstrate how to perform this function using the Ford Kuga model as an example. Body Control Module (BCM) Collision Data Clearing Function Introduction: After a collision, this function clears the collision data records stored in the Body Control Module so that the vehicle can be restored to its factory default state ("No Collision" or "Repaired") after repair. This function involves the vehicle’s safety systems. Before performing this operation, it must be ensured that the vehicle’s collision-related components (such as airbags, seatbelt pretensioners, sensors, etc.) have been inspected and replaced to be in good working order by a professional mechanic. Otherwise, after clearing the data, the safety systems may not function properly in the next collision, posing a serious safety hazard. Devices that support this feature: LAUNCH X431 PRO3 series , X431 PAD se...

  The LAUNCH X431 truck diagnostic tool performs the cutout cylinder function on a 2019 Foton Pilot truck. Background information on the function: When an engine experiences problems such as unstable idling, insufficient power, vibration, black smoke, or abnormal noise, it is impossible to directly determine which cylinder is malfunctioning based on visual inspection. The Cutout Cylinder Test can effectively narrow down the scope of the fault and determine which specific cylinder is malfunctioning. Cutout Cylinder Test : When the fuel supply (diesel engine) or ignition (gasoline engine) is cut off, the engine will show significant changes such as reduced speed and increased vibration due to a noticeable drop in power. This is normal. If the engine’s operation remains almost unchanged after cutting off a particular cylinder, it indicates that the cylinder itself is either not working or is working very poorly, and is the source of the fault. For modern electroni...

 The LAUNCH XPROG3 with PC Adaptor can perform operations such as cloning vehicle ECUs. This is similar to the X431 ECU & TCU Programmer . So what are the differences between the two? This article will answer that question. Answer: The LAUNCH X431 ECU & TCU Programmer supports reading and writing vehicle ECUs, verification, and IMMO OFF functionality. It has its own PC software and is a fairly comprehensive ECU programming tool. However, it cannot be used with the X431 diagnostic tool, nor can it perform key programming tasks. The LAUNCH XPROG3 , when used with the X431 diagnostic tool, can perform key programming on various vehicles, as well as engine and transmission replacement. When the XPROG3 is used with the PC Adaptor , ECU programming software can be used for ECU cloning and programming. Furthermore, the XPROG3 + PC Adaptor has the same functionality as the LAUNCH X431 ECU & TCU Programmer. Both companies have the same policy and pricing for ...

 In 2026, the diagnostic tool market has shifted — it is no longer about who has the most features, but who offers the most functional value per Euro. For workshop owners, selecting the right equipment is a critical investment decision. In this guide, we analyze the four standout performers of the year — the LAUNCH X431 PRO3 , X431 PRO(V5.0) , X431 PRO Elite , and CRP919X BT — to help you identify the best ROI for your specific business needs. 2026 Value Comparison Matrix Quick-Reference Value Comparison Legend: ● = Supported | ◎ = Expandable | — = Not Supported The Powerhouse: LAUNCH X-431 PRO3 (V+ 5.0) Price: €723 | Best For: Workshops requiring advanced visualization and heavy-duty scalability. The PRO3 remains the flagship of the "Value" category. While it is the most expensive on this list, its value lies in diagnostic speed and visual clarity. Intelligent Topology Mapping: Unlike lower-tier models, the PRO3 offers a visual representation of the v...

 This article will introduce how to clone a Kia Bosch MEG17.9.12 ECU using the LAUNCH X431 ECU tool ( XPROG3 + PC Adaptor / X431 ECU & TCU Programmer ). The demonstration uses LAUNCH XPROG3 + PC Adaptor ; the same operation can be performed using X431 ECU & TCU Programmer. 1) Open the XPROG3 PC Adaptor software and search for "MEG17.9.12" in the search bar. Click on the corresponding ECU in the search results and select BENCH mode. 2) Click [Direct connection of diagram] and connect the ECU according to the wiring diagram. 3) After connection, click [Read ECU information] -> [Read complete data] in sequence. Save the read file, and then click [Disconnect] . 4) Replace the ECU that needs to be replaced and rewire it. After rewiring, click [Read ECU information] , then click [Write complete data] to write the original data back to the ECU. 5) After the software prompts "Data is successfully written," click [Disconnect] . The ECU clon...
