Autel and the SGM work around
Today I was called to a body shop with an Autel scanner and the SGM cable 2019 Ram 1500. The tech said that the vehicle said tamper detected on dash and would not start. I hooked the witech 2,.0 up and the vehicle had 57 codes across many modules all pointing towards a tamper. I cleared the codes and the truck started. I really did not expect it to work and therefore did nt take any photos. As I am completing the vehicle I notice it has a manufacturer tag on it. Makes me wonder is Chrysler is working on a update to fight the Autel. I had never see this before. The vehicle was all back together. I almost wish I had taken back apart and tried the autel again. Being a mobile guy I just collected my pay and moved on. too much to do too little time.
What are your thoughts? Or was this just a fluke? maybe the tech did something before I got there.

Did you happen to do a pre and post scan? Would like to have seen all the codes.

AutoProPad also has a cable that includes back probes to backprobe the gateway. With these solutions you don't have to disconnect anything. It just simply adds another access to the CAN traffic. The Double…
As 18 and newer Chrysler products are not aftermarket friendly to code clearing some of the body shops that are part of a large chain using the Autel have been instructed to use the new Autel cable as a workaround for clearing codes. Now we are seeing where the shops are removing the Radio to access the connectors in an attempt to get a clean post scan. This is causing no starts and in many…
