Like many car enthusiasts and DIY mechanics, I embraced OBD2 scanners as soon as they became available post-1996. My first purchase, an Actron scan tool, was a game-changer. While it had its limitations – no access to other modules or ABS cycling – it was invaluable for basic diagnostics and triggering engine controller tests, especially for O2 sensor function checks. At around $250 back then, it was a significant investment, but it quickly paid for itself through saved repair costs and diagnostic insights.
My positive experience with Actron has me considering their newer models, particularly the CP9695. This model boasts advanced features, including ABS pump cycling – a crucial function for thorough brake system bleeding. The Innova CarScan Tech 5510 also looks like a strong contender in this category, sparking my interest.
However, I’m also reflecting on my actual need for ABS pump cycling. In reality, I’ve only bled brake and clutch hydraulic systems a couple of times on cars I’ve owned since 2002. I’ve often found it more convenient to have a professional service handle brake/clutch fluid flushes during routine oil and filter changes when the car is already on a lift.
Watching experienced technicians perform brake bleeding is quite enlightening. Using pressure bleeders and diagnostic tools to cycle the ABS pump, they can efficiently bleed the entire system without needing an assistant. They connect a catch bottle to each caliper’s bleed valve nipple, quickly flushing out old fluid and replacing it with fresh fluid. This process, including ABS cycling, is remarkably fast and effective in the hands of a skilled tech.
While I have manually bled brakes a couple of times for the learning experience, the convenience and speed of professional service, particularly for tasks like ABS bleeding, are hard to ignore. For occasional brake fluid flushes, entrusting this task to professionals equipped with the right tools, including ABS cycling capabilities, might be the most practical approach, especially when considering the infrequent need for this service.
