Circuit/System Description

WARNING: This page is about a different car, the 2014 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.

The side blind zone alert system uses side object sensors located behind the rear fascia at each of the vehicles rear corners. Visual indicators located in the right and left outside rearview mirrors alert the driver to the presence of objects of interest within the corresponding blind spots, or zones, on each side of the vehicle. The system is controlled by the Vehicle Personalization settings located in the radio.

Each sensor receives battery power, ground, as well as serial data communications. The left and right sensors are identical, however an additional ground circuit is required to configure the sensor for operation on the right side. Communication is via a serial data and each sensor shares the serial data circuit in parallel, allowing continuation of communication between the sensors. The scan tool is able to communicate with each sensor independently. The side object sensors control corresponding mirror icons by sending power to the individual LED indicators.
