Years ago, after OBD2 systems became standard in vehicles around 1996, I invested in an Actron scan tool. Back then, these devices were quite basic compared to today’s technology. My Actron scanner primarily focused on engine diagnostics and supported limited functions like triggering built-in engine controller tests to assess O2 sensor performance. It was a significant purchase at around $250, but it proved to be a worthwhile investment, paying for itself many times over by helping me diagnose and fix car issues myself.
My positive experience with Actron has me considering purchasing a more advanced model, perhaps the CP9695. This newer scanner boasts enhanced capabilities, including access to additional control modules and ABS pump cycling, which is useful for brake system bleeding.
However, the Innova CarScan Tech 5510 also looks like an intriguing option, representing the advancements in Portable Obd2 Scanner technology. These handheld devices have come a long way from the basic code readers of the late 90s.
Thinking about features like ABS pump cycling brings to mind brake bleeding. In my personal car maintenance history, I’ve only performed brake and clutch hydraulic system bleeding a couple of times, particularly with vehicles I’ve owned since 2002. I found it convenient to have this service done professionally when my car was already in for routine maintenance like oil and filter changes, coinciding with recommended brake/clutch fluid flushes.
Watching professional technicians perform a brake bleed is quite efficient. With the car lifted, they utilize pressure bleeders, eliminating the need for a helper. The process is swift; a technician can quickly move around the vehicle, attending to each brake caliper in turn. They use a catch bottle connected to the bleed valve to collect the old fluid. As soon as the valve is opened, the old, discolored fluid flows out, replaced by fresh fluid. Once the fluid appears clean, the valve is closed, and the process is repeated at the next caliper. Crucially, they use a diagnostic tool to cycle the ABS pump, ensuring a complete and thorough bleed.
While I don’t recall the exact cost of this service, I remember it, along with manual transmission and differential fluid changes, being among the more reasonably priced services at the dealership.
I did undertake brake bleeding myself a couple of times purely for the learning experience. While it was valuable to understand the process, I concluded that professional service was often more convenient for this particular task. However, for general diagnostics and fault finding, a portable OBD2 scanner remains an invaluable tool for any car owner or DIY enthusiast. The ability to quickly read and clear codes, monitor live data, and perform basic system checks with a portable OBD2 scanner can save significant time and money, empowering individuals to understand their vehicle’s health and address minor issues before they escalate into major repairs. The evolution of the portable OBD2 scanner has truly put diagnostic power into the hands of everyday drivers.
