System Operation and Component Description: Diagnostics

WARNING: This page is about a different car, the 2019 Jaguar XJ and 2018 Jaguar XJ. However, it is still accessible from the selected car via links, so may be relevant.

The ECM stores each fault as a Diagnostic Trouble Code (DTC). The DTC and associated environmental and freeze frame data can be read using JLR 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.
