In today’s video, I take you through a real-world diagnostic challenge on a 2013 Ford F-150 that kept losing communication with the PCM. The truck would randomly refuse to talk to the scan tool, showing “No Communication” errors and causing all kinds of confusion.
Using proper diagnostic strategy, wiring diagrams, and step-by-step testing, I tracked the issue down to something completely unexpected — a bad fuse connection inside the fuse box. This intermittent power supply was causing the PCM to drop offline.
Whether you’re a DIYer, a tech in training, or a professional looking to sharpen your electrical diagnostic skills, this video breaks down the entire process clearly.
