Like many auto enthusiasts, I’ve witnessed firsthand the evolution of car diagnostics. Back in the day, shortly after OBD2 became standard in 1996, I invested in an Actron scan tool. It was a relatively basic device, lacking advanced features like control module access or ABS pump cycling. However, it provided a crucial function: triggering built-in engine controller tests, particularly for checking O2 sensor function. At around $250, it was a significant expense then, but it quickly proved its worth by saving me time and money on repairs.
My positive experience with Actron has me considering their newer models, specifically the CP9695. This tool boasts enhanced capabilities, including ABS pump cycling, which is particularly useful for thorough brake system bleeding. The Innova CarScan Tech 5510 also caught my eye as another interesting option in the market of advanced OBDII and EOBD scan tools.
Reflecting on brake maintenance, I realize that I’ve only performed brake and clutch hydraulic system bleeding myself a couple of times, primarily on vehicles I’ve owned since 2002. In most cases, I found it more convenient to have this service done professionally during routine oil and filter changes, especially when the brake/clutch hydraulic system was due for a flush.
Professional technicians handle brake bleeding efficiently and routinely. With the car lifted, the process is streamlined. They often use pressure bleeders, eliminating the need for a helper. I’ve observed technicians perform this service, and their speed and efficiency are impressive. Using a catch bottle connected to the bleed valve, they systematically cycle through each brake caliper. The old fluid is quickly replaced with fresh fluid, and the diagnostic tool is used to cycle the ABS pump, ensuring a complete bleed.
While I don’t recall the exact cost of this professional brake bleeding service, I remember it being one of the more reasonably priced services at the dealership, along with manual transmission and differential fluid changes. While I gained valuable experience bleeding brakes myself a few times, I concluded that for me, professional service offers a balance of convenience and effectiveness.
Modern OBDII and EOBD scan tools have revolutionized automotive diagnostics, offering capabilities far beyond basic code reading. Features like ABS pump cycling for brake bleeding, once considered advanced, are becoming increasingly accessible and essential for comprehensive car maintenance. For anyone serious about DIY car care or understanding their vehicle’s systems, investing in a capable OBDII/EOBD scan tool with ABS functionality is a worthwhile consideration.
