The PCS is located in a slot behind the bumper foam on the front bumper beam and is secured with a single fixing.
At the end of the sensor next to the fixing there is a PCB and fibre optic transceiver, which is connected to a fibre optic cable configured in a loop. The PCS uses this fibre optic loop to detect an impact by measuring the amount of light returned to the fibre optic transceiver. A reduction in light levels occurs when the PCS is deformed by an impact. The PCS monitors the level of light returned from the loop, if a reduction of a predetermined magnitude is measured a trigger signal will be sent to the control module.
