Pedestrian Protection System (G1818072): Operation

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.

The pedestrian protection system is active at vehicle speeds between 25 to 50 km/h (15 to 31 mph).

Hood deployment controls are triggered by pressure sensors mounted on either side of the front bumper. The pressure sensors are attached to each end of a silicon pressure tube which is mounted on the inside of the front bumper. An impact creates a pressure pulse inside the silicon tube which is detected by the two pressure sensors. The pressure sensors transmit a digital status signal to the RCM which fires the hood deployment controls if the operating parameters are met.

The RCM receives information about the vehicle's current speed from the ABS (Anti-lock Brake System Control Module) on the HS (High Speed) CAN (Controller Area Network) powertrain systems bus. If the predetermined parameters are met the RCM fires the hood deployment controls which force the rear of the hood upwards. The raising of the hood creates a more cushioned effect between the vehicle and the pedestrian.

The RCM will send a signal to the BCM/GWM (Body Control Module/Gateway Module) on the HS CAN powertrain systems bus to activate the hazard warning lights. The hazard warning lights can only be switched off by pressing the engine start/stop button to turn the engine OFF and ON again (without pressing the brake pedal) to revert to the ignition convenience mode.

A warning message to check the pedestrian protection system will appear in the IC (Instrument Cluster). The vehicle must not be driven once the hood has been deployed.
