The object alarm system will use the front or rear parking assist (RPA) display indicators and the radio speakers to notify the driver when an object is within the object alarm system field of view. Power is provided to the RPA display by the object alarm module via the RPA display supply voltage circuit. The RPA display indicators are controlled by the object alarm module via the indicator control circuits. The object alarm module also provides the ground for the indicator control circuits.
