Works good and makes things nice. I use it all the time and highly recommend. Review: Great tool. I should have bought this ages ago. - I have been working on cars for many years. I sometimes would have to probe the DLC port to get readings and that would spread the pins over time. I just replaced the OBD2 on my oldest car for that reason. This tool saves the port and makes it easy for me to probe and get readings, and jump pins if needed. It also shows the active lines in real time through the LED lights as it's hooked up. Plus volts and amperage. I haven't needed to program any ECU's since I've had it. But I know it will be a lot easier with this. And the through port let's me place my scantool directly to preform multitasking test together. I recommend this for the mechanics at home or in the shops. ## Features - 【ECU Bench Tool】 GT100+ allows you to power an ECU on the bench; you can easily do diagnostics, vehicle immobilizer, and security work, whether it is on the bench with the included power adapter, or in the vehicle with the OBDII port supplied power. - 【Added CAN BUS and K-LINE Protocol】GT100+ not only check all obd2 diagnostic socket pins, but also non-standard OBD2 protocols, like the port 1,9,3,11,12,13,and 8.
