I checked all the fuses and replaced still no power does anyone know what I have to do to get power so I can pull codes my transmission is in Limp mode.. my code reader works in my other vehicle not getting any power from my DSM.

These were both together, the white one was clipped with the black one with one wire running to it.

Checked the power and the ground for ecu to start. Pull the diagram and identify the power and ground on the pins obd connector. Check continuity on the communication lines and identify all modules on the circuit. Remove one at a time to see if communication will restore.
