Years ago, after OBD2 systems became standard around 1996, I invested in an Actron scan tool. While it was somewhat limited compared to today’s tools—lacking access to modules beyond the engine control unit and features like ABS pump cycling—it was invaluable for its ability to trigger built-in engine tests, particularly for checking O2 sensor function. This scanner, costing around $250 at the time, proved to be a worthwhile investment, paying for itself many times over through saved diagnostic costs and DIY repairs.
My positive experience with Actron has me considering their newer models, specifically the CP9695. This scan tool 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, offering similar features in the ABS diagnostic and service category.
However, I must consider how often I actually perform brake bleeding. Looking back, I’ve only bled brake and clutch hydraulic systems a couple of times on cars I’ve owned since 2002. In most cases, I’ve found it more convenient to have the brake and clutch fluid flushed and bled during routine oil and filter changes at a service center, especially when the system is due for maintenance anyway.
Professional automotive technicians handle brake bleeding regularly and efficiently. With a vehicle lift, the process becomes significantly easier. They typically use a pressure bleeder, eliminating the need for a helper to pump the brake pedal. I’ve observed this process firsthand and been impressed by how quickly a technician can move from caliper to caliper. Using a catch bottle connected to the bleed valve, the old fluid is efficiently extracted. They monitor the fluid until fresh fluid appears, then close the valve and move on to the next wheel. Crucially, they utilize a diagnostic tool to cycle the ABS pump, ensuring all air is purged from the system. This step of ABS pump cycling is a key advantage when using an Abs Obd2 Scan Tool for a complete brake bleed.
While I don’t recall the exact cost of this professional brake and clutch bleeding service, I remember it being one of the more affordable services at the dealership, alongside manual transmission and differential fluid changes.
I have performed DIY brake bleeding a couple of times, mainly for the learning experience, but those two experiences were enough to make me appreciate the speed and convenience of professional service, especially when considering the added benefit of ABS cycling with specialized tools. For DIY enthusiasts, though, an abs obd2 scan tool with ABS cycling capabilities offers a powerful way to perform thorough brake maintenance at home.
