Wanted to make note of a discovery. 2016 and newer for us Renegade owners and 2018 and newer (plus or minus a few years on select models) of Fiat, Chrysler, Dodge, Jeep, Ram vehicles. We have a module called a Secure Gateway Module which prevents any and all commands minus code reading from any OBDII connector. This is because the Cherokee hack and control a while back. We have to get a special connector a 12+8 pin, disconnect out SGM and plug the this connector into the 2 plugs that were plugged into the SGM. Ours is by the OBDII Plug up kinda around the brake pedal. Luckily its not like the ram pickup its behind/under the radio. So we can only read no erasing, bi directional etc. unless we plug this special connector in.
