<p>If you’re looking to start a Jeep PCM (Powertrain Control Module), you’ll need to disconnect the battery, then locate the PCM (usually near the engine). Unplug the old PCM and install the new one by reversing the process. Always make sure the new unit is programmed for your Jeep model to avoid issues. And speaking of repairs, if you ever need Mini Cooper Repair, I recommend checking out the Mini Cooper Repair Abu Dhabi Specialist Repair Workshop for expert service!
