223: Honda Civic Crank No Start
About this episode
A detailed diagnostic journey on a 2009 Honda Civic with a crank-no-start issue reveals complexities beyond a simple starter or battery problem. The host explores communication failures with the PCM and immobilizer modules, unusual power feed configurations, and the impact of a potentially reversed battery connection. Through methodical testing of grounds, power supplies, and data lines, the culprit is identified as a dead PCM. The episode highlights the importance of systematic troubleshooting, understanding module interdependencies, and the quirks of Honda’s electrical systems, culminating in a successful PCM replacement and vehicle start.
Today on the show I share a case study on a 2009 Honda Civic crank no start. I can’t communicate with the immobilizer module or the PCM. Join me as I work trough my process to get to a solution!
