ECM Troubleshooting

AN ECM is simply a computer that operates in a network in your vehicle. ECM’s only function correctly when they are integrated into your vehicle’s network security and operating system. As a result there are many problems associated with ECM repair and replacement that can only be seen or diagnosed with the ECM installed in your vehicle’s network and using an OEM specific scan tool.
