Principles Of Operation: Diagnostics

WARNING: This page is about a different car, the 2011 Jaguar XK and 2010 Jaguar XK. However, it is still accessible from the selected car via links, so may be relevant.

The engine control module (ECM) stores each fault as a diagnostic trouble code (DTC). The diagnostic trouble code (DTC) and associated environmental and freeze frame data can be read using Jaguar approved diagnostic equipment, which can also read real time data from each sensor, the adaption values currently being employed and the current fueling, ignition and idle speed settings.
