Rewrite the ECM with the car's original VIN and mileage by using the scan tool before you install it to prevent the DTC. First, check if the pins in the ECM and other electrical connectors show any rust or damage and if they are evenly placed; make the needed repairs before going any further. After that, link the two electrical connectors to the ECM, fit it into its place and tighten the mounting screws to 4 Nm (35 in. lbs.). Then, fasten the plastic shield onto the electrical connectors, so it fits securely and finally, attach the negative battery cable. Change the settings on the ECM back to the correct ones using the vehicle's VIN and mileage.

How to Properly Remove and Reprogram an Engine Control Module on Jeep Wrangler?

The PCM (Powertrain Control Module) is usually in the engine compartment by the side of the windshield washer reservoir tank. To ensure everything works as it should, you should reprogram the new Powertrain Control Module using the car's original VIN and mileage with a diagnostic scan tool or you risk it giving a Diagnostic Trouble Code (DTC). Always stop the ignition, take out the negative lead from the battery and unplug the PCM wiring in order to protect against voltage spikes. Unplug the negative battery cord from the battery and then remove the plastic shields covering each of the four electrical connector ends. Take out the three mounting bolts from the PCM, then disconnect all four electrical connectors and lift the PCM out from the vehicle.
