For years, even since OBD2 systems became standard in 1996, having a personal scan tool has been incredibly beneficial for car owners. I recall purchasing an Actron scanner shortly after OBD2 was introduced. While it had limitations – lacking access to modules beyond the engine control unit and not capable of ABS pump cycling – it was invaluable for basic diagnostics, like triggering built-in engine tests for O2 sensor function checks. That scanner, costing around $250 at the time, proved to be a worthwhile investment, paying for itself through saved diagnostic costs and informed repairs.
My positive experience with Actron has me considering another purchase, specifically the CP9695 model. This newer scanner boasts enhanced capabilities, including ABS pump cycling, which is particularly useful for thorough brake system bleeding. The Innova CarScan Tech 5510 also looks like a compelling option in the current market.
However, I must consider how often features like ABS pump cycling are truly necessary for a DIYer. In my own experience, I’ve only performed brake and clutch hydraulic system bleeds a couple of times on cars I’ve owned since 2002. Often, I’ve found it more convenient to have the brake and clutch fluid flushed and bled professionally when the car is in for routine services like oil changes.
Professional automotive technicians handle brake bleeding frequently and efficiently. With a vehicle lift, the process is streamlined. They typically employ pressure bleeders, eliminating the need for a helper. I’ve observed technicians swiftly move from caliper to caliper, bleeding the system. They use a catch bottle connected to the bleed valve to collect the old fluid. Opening the valve releases the old fluid, and they close it once fresh fluid is visible, then repeat the process at each wheel. Crucially, they utilize a diagnostic tool to cycle the ABS pump during the bleed, ensuring a complete fluid exchange. This ABS pump cycling is a key advantage of using professional Abs Scanners Obd2 tools.
While I don’t recall the exact cost of this professional brake bleeding service, I remember it being among the more affordable services at the dealership, alongside manual transmission and differential fluid changes.
I have manually bled brakes myself a couple of times, purely for the experience and to understand the process. However, after those experiences, I concluded that professional service, particularly when considering the benefits of abs scanners obd2 for ABS pump cycling, offers a convenient and effective solution for brake system maintenance. For ensuring optimal brake performance and longevity, especially in vehicles equipped with ABS, using abs scanners obd2 for thorough bleeding is a significant advantage, whether you choose to DIY or opt for professional service.
