Flash 1997 Chevrolet truck engine code ecm?

There isn't a single "ECM code" for a 1997 Chevrolet truck. The ECM (Engine Control Module) stores diagnostic trouble codes (DTCs) which are specific to the problem detected. The code "E" is usually not a standalone code; it's a prefix that might indicate something about the system involved, but the actual code consists of more digits, often a letter followed by a number (e.g., P0123, P1234).

To find the specific trouble codes stored in your 1997 Chevy truck's ECM, you will need to:

* Use an OBD-II scanner: This is the most reliable method. Plug the scanner into the OBD-II port (usually under the dash) and read the codes. The scanner will translate the codes into descriptions of possible problems.

* Check the owner's manual: Your truck's owner's manual *might* have a section on how to retrieve diagnostic codes using a less sophisticated method (like a jumper wire technique), but this is less common with OBD-II equipped vehicles.

* Visit a mechanic or auto parts store: Many auto parts stores will read the codes for free as a service to encourage parts purchases.

Once you have the actual codes, you can then search online (or consult a repair manual) for the meaning and potential solutions. Searching for something like "Chevrolet truck OBD-II code P0123" (replace P0123 with your actual code) will give you relevant information.
