I have a problem on my 2013 Jeep Wrangler, namely there is no communication between the PCM and the TCM, the problem appeared after I removed the TIPM without clamping the (+) and (-) poles or researching it. What am I doing ?

It's possible that a relay or fuse went out. Scan your vehicle with an OBDII scan tool and find out what codes it's showing. Find out which module your module isn't able to communicate with to dial down on where the issue is.If the CAN bus is down, check for grounding and any signs of corrosion. Make sure all the plugs are free of debris and dirt and re-install all the plugs into the TIPM after carefully inspecting it.Try a hard battery reset and scan the vehicle again for codes. https://forum.upfix.com/ecu/ecu-hard-battery-reset-troubleshooting/
