Actron CP9550 PocketScan Plus Review (Updated 2018)

Before we talk about the Actron CP9550 PocketScan Plus Review, here are some important things to remember when the check engine light suddenly presents its ugly face:

1. If you notice something unusual with your vehicle such as engine stuttering, engine malfunction or if the engine misfires, reduce your speed immediately and park the car as soon as possible. You should keep the engine running, even if the check engine light is on. This will allow you to assess the overall condition of the vehicle, and if it is safe to proceed driving.

2. If the check engine light is present, and if the car seems fine, you can proceed driving with caution. It is better to bring the car to a garage, or drive to your favorite mechanic. Without a proper scan tool, it is hard to determine the cause of the engine malfunction light. Thus the reason to bring your car to a mechanic as soon as possible.

3. If your car is relatively new, or if your vehicle is still covered by the warranty, do not hesitate to visit the dealership/service center. Take advantage of your warranty. Why pay large sums of cash if the dealership is obliged to fix your car for free or at a lower cost?

But for those who drive older cars, it is wise to invest in your own OBD2 vehicle scanner. Imagine the savings that you can enjoy if you have a tool that you can plug-in and diagnose the error code yourself. Read on for the complete Actron CP9550 PocketScan Plus Review.
