Model: 2011 chev express 3500 Fault Code: U0100 Posted: 2016-01-30 19:03

Hello, I'm experiencing a similar issue with my 2011 Chevrolet Express 3500 van. The vehicle shuts down completely and will not restart until it has been sitting idle for approximately 30 minutes. A diagnostic check reveals the fault code U0100. I'm looking for any insights or guidance on how to resolve this issue. Has anyone else encountered this problem? Any suggestions on potential causes or troubleshooting steps would be greatly appreciated.

Loss of communication between vehicle modules may be the root cause. Have you added any aftermarket electrical devices, such as a radio, theft deterrent system, or GPS tracking device? Any additional electronics could interfere with the vehicle's network.

Our vans are equipped with GPS trackers. I'll disconnect them to see if that resolves the issue. Thanks for the tip.

Unplugging additional electrical devices is a good first step. General Motors has issued a Technical Service Bulletin (TSB) indicating that certain aftermarket systems may interfere with the vehicle's network, potentially violating professional standards.
