As the control center of the fuel injection system, the electronic control module constantly monitors information from various sensors, including the opening times (pulse width) of the injectors. It can diagnose operational problems, alert the driver through the "check engine" light, and store a code or codes which identify the problem areas to assist in making repairs. This unit also houses the PROM (Programmable Read Only Memory) or MEM-CAL (computer chip) which contains specific calibrations for a given engine.
When sending in exchange, the ECM must not have any visible evidence of damage or fluid intrusion. Keep the chip out of your original ECM.
Core must be returned in the box that the rebuilt one comes in.
