Review on OTC Tools 3208 OBD II & ABS Scan Tool: Enhanced Engine, Transmission Codes - Blue by Jeff Richmond

Better than expected! Works on our 2010 Silverado, 2008 Impala and even 1995 Blazer. On two new cars it shows a TON of live engine data and can pull and clear ABS codes. The Blazer also showed real-time data, but not much, and couldn't read the ABS. For ABS, select a vehicle and it only lists Ford for 1995 trucks. My understanding is that GM switched to OBD2 in 95-96 so we had luck with engine codes but not ABS. The manual lists 5 pages of real-time data it can display depending on the vehicle. These include voltages on specific sensors, engine load and speed, fuel trim, fluid and intake air temperatures. Excellent data for troubleshooting engine problems that may not trigger a trouble code. I don't know why, but both Autozone and Tires Plus couldn't get codes for Blazers. This reader immediately found the O2 sensor code and using real time engine data we were able to diagnose engine problems. My only complaint is that the text on the screen is small and there is no backlight, making it difficult to read. But with good lighting this is not a problem.
