Years ago, after OBD2 systems became standard in vehicles in 1996, I invested in an Actron scan tool. Back then, these tools were more basic. Mine was good for reading engine codes and running some basic tests, like checking O2 sensor function, but it didn’t offer advanced features like accessing other control modules or ABS pump cycling. Still, at around $250, it was a worthwhile purchase that paid for itself through saved diagnostic costs over time.
My positive experience with Actron has me considering purchasing a newer model, possibly the CP9695. This model seems to offer more advanced capabilities, including ABS pump cycling, which could be useful for brake system bleeding. I’ve also noticed the Innova CarScan Tech 5510, which looks like another interesting option in the Obd2 Abs Scanner market.
However, when I think about it, I’ve only had to bleed brake and clutch hydraulic systems a couple of times in recent years – specifically in cars I’ve owned since 2002. Often, I found it more convenient to have this service done professionally when the car was already in for routine maintenance like an oil change and the brake/clutch fluid was due for a flush.
Watching a professional technician perform a brake bleed is quite efficient. With the car on a lift and using a pressure bleeder, it’s a quick, solo job. They connect a catch bottle to each brake caliper bleed valve in turn. As soon as the valve is opened, the old, discolored fluid is expelled, replaced by fresh, clean fluid. The technician then closes the valve and moves to the next caliper. Crucially, they use a diagnostic tool to cycle the ABS pump during the process, ensuring a thorough bleed. This is where an obd2 abs scanner with ABS cycling capability becomes invaluable for a complete brake service.
I recall the cost for this service being quite reasonable, especially considering the convenience. Services like brake bleeding and manual transmission/differential fluid changes were among the less expensive services I opted to have done at the dealership.
While I have performed brake bleeding myself a couple of times to gain the experience, I’ve concluded that for me, professional service is often the more practical and time-saving approach. However, for those who prefer DIY car maintenance, investing in a quality obd2 abs scanner with ABS functionality could be a worthwhile investment, especially if you plan to perform brake fluid flushes regularly. Having the ability to cycle the ABS pump with an obd2 abs scanner ensures a more complete and effective brake bleeding process, whether you choose to do it yourself or understand the process better when discussing it with your mechanic.
