The Chevrolet C0550 43 Code is a diagnostic trouble code that indicates an issue with the electronic control unit (ECU) EEPROM programming. This code is typically triggered when the ECU detects an internal fault when power-up is commanded. While there are no specific voltage or ground requirements, the program still runs even if the voltage is outside of the valid operating range. It is important to understand the potential causes and solutions of this code to address the underlying issue and restore normal ECU operation.
