To accurately determine whether a PCM malfunction is present, visual inspection and driving experience alone are often insufficient. Professional diagnostic tools such as the Autel Scanner can read vehicle fault codes and view real-time data streams, helping you distinguish between a PCM fault and related issues such as sensors or wiring.
Therefore, when an engine malfunctions, people often consider whether the EGR valve is faulty. At this time, the Autel scanner's bi-directional control function (active test) is often needed to diagnose and troubleshoot the fault to check whether the EGR valve is the problem.
Diesel particulate filters (DPFs) provide a balance between performance and emissions control for diesel vehicles.How does DPF regeneration actually work? What role does the Autel scanner play in it? And how long does the whole process typically take? Let's take a look.
This article explains the working principles of a MAP sensor (manifold absolute pressure sensor), lists seven common malfunction symptoms and causes, and explains how to quickly locate the problem using professional auto diagnostic tools like the Autel scanner, as well as common repair methods.
Unlike the previous overview of resetting the oil light using an Autel scanner, which generally applies to general scenarios but may vary slightly depending on the Autel scanner model, today we'll detail how to reset the oil light using the Autel MX900 scanner, a popular model on our website. Let's take a look.
The P0446 fault code is a common OBD-II diagnostic code, standing for EVAP System Vent Control Circuit Malfunction.In the previous article, we introduced the signs of EVAP system failure. Today, we will mainly explain the fault code P0446 and see which part of the EVAP system failure it is related to.
Therefore, it is very important to have a car diagnostic scanner that can bleed ABS air at this time. It can make the operation simpler and save you the trouble of finding a professional technician for repair. You can easily bleed ABS air at home. Let's take a look at how to use the Autel scanner to bleed ABS air.
Experiencing engine misfires or a rough idle can be alarming for any driver. These symptoms often indicate that your vehicle is not running optimally, which may lead to reduced performance, lower fuel efficiency, and potential long-term engine damage if not addressed promptly.
When the ABS light comes on, most drivers feel a jolt of worry — and for good reason. The ABS light signals that your anti-lock braking system isn’t operating normally. While your primary brakes often still work, the safety net that prevents wheel lock-up in emergency stops is compromised.
When your check engine light pops on and a scan shows OBD Code P2172, the throttle actuator control system has detected sudden high airflow. Using an Autel scan tool helps you confirm the fault quickly, view live data, and avoid guesswork.
The engine control unit (ECU) is the brain of every modern vehicle, managing critical functions such as fuel injection, turbo boost levels, and overall engine performance. However, if your car has been operating under abnormal conditions—such as faulty sensors, poor...
Regular tire maintenance not only improves safety but also helps extend the life of your vehicle. Here are some simple checks every driver should do, using tools like Autel TPMS tools to make the job easier and more accurate.
