Awesome item. Detected a code for glow plug #3 faulty. I changed the faulty plug and reset the trouble codes using this item. 2020 F250 Diesel engine light went out. Works as advertised.

  • Resets MIL every time, even if not intended.
Works ok but resets the Malfunction Imdicator Light (MIL) every time I hook it up meaning I can’t get it inspected for some time after I’ve used it. The MIL indicates that the car has gone through the entire routine diagnostic cycle that it does continually. If it lights, there’s a problem. If it stays off, you should be OK. However if you try to verify the OK status, your MIL goes back to zero, the light goes out and your system diagnostics start from scratch. This is a fatal flaw because it means that using this machine will make it impossible for you to get your car inspected until the entire normal auto diagnostic system runs its normal course again. Usually days. And, do not hook it up again just to check or you will be reset back to zero on the MIL. Additionally, the controls are counter intuitive in some elements. Overall, not terrible, ok for reading codes and even real time data, but I would not buy again because it resets the MIL every time and it should not do that. ... show more
