The tech said I need to get the ECM fixed. What is the ECM, Electric engine control module or electric chassis control module? The car runs okay but some times cuts off Mostly when I make sharp turns but comes right back on. HELP!

Thank you,

A. With this many codes I would point to the ECM myself. It's the Electronic Control Module. The computer that runs the engine.
