### ⭐⭐⭐⭐⭐ *** Great product, Good price, Fast delivery, Nice seller ***

*** Great product, Good price, Fast delivery, Nice seller ***

### ⭐⭐⭐⭐⭐ Great tool!
*by J***Y on June 24, 2023*

Bought this a few months ago to expand my troubleshooting capabilities. Yesterday I finally broke it out of the box. Had to prove to a fellow mechanic that the ecm we'd been sent was bad vs the vehicle systems. This kit made it all very plug and play with the ecm, my scantool, and an oscilloscope. And the tools laid out on the bench while we tested it made my senior mechanics head spin off. Next level gained!

### ⭐⭐⭐⭐⭐ It didn't come with instructions to connect it to the DLC port.
