Electronic Traction Control

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

Electronic Traction Control (ETC) tries to optimize forward traction by reducing the engine torque, or by applying the brake of a spinning wheel until traction is regained.

ETC is activated if an individual wheel speed is above that of the vehicle reference speed (positive slip) and the brake pedal is not pressed. The brake is applied to the spinning wheel, allowing the excess torque to be transmitted to the non-spinning wheel through the drive line. If necessary, the Anti-lock Brake System (ABS) control module also sends a message to the Powertrain Control Module (PCM) to request a reduction in engine torque. The message comes on the High Speed (HS) Controller Area Network (CAN) chassis systems bus and Flexray.

When the Dynamic Stability Control (DSC) function is selected off using the DSC switch, the braking and engine torque reduction features are both disabled.
