ECM Default Actions

WARNING: This page is about a different variant/trim than selected.

When a malfunction occurs within the engine control system, the engine control module (ECM) maintains control of the system with Default Actions. Default Actions are calculated values, and/or calibrated default values, that are stored within the ECM. A certain level of engine performance is possible when a malfunction occurs dependent on the Default Actions taken. The ECM Default Actions prevent a complete loss of engine performance.
