Diagnostic Fault Information

Circuit/System Description

The object alarm sensors are 3-wire sensors that are used to determine the distance between the vehicle and an object of interest. The object alarm

module supplies 8 V to the object alarm sensors via the 8 V reference circuit and provides ground via the low reference circuit. The object alarm

module triggers the sensors in a sequential loop. After each sensor transmits, the object alarm module uses the sensor echo received through the

signal circuit to calculate the distance and position of an object.
