Code P10E1 GMC Description

The Engine Control Module (ECM) contains a microprocessor used to process input data to control outputs. The control module controls a series of actuators to ensure optimal engine performance. The control module does this by reading values from a variety of sensors, interprets the data and adjusts the engine actuators accordingly. Relays are used to control a high-power circuit with a low power signal. The output circuit is switched to the ground to activate the component. The Diagnostic Trouble Code (DTC) will be set when the Control Circuit is open for greater than 1 s.
