Code B1E3A Cadillac Description

The object alarm detection system senses how close the vehicle is to an object. The distance is determined by the 4 ultrasonic sensors located in the rear and front (if equipped) bumpers. The object detection system will notify the driver when backing up while parking at speeds less than 8 km/h (5 mph). The object detection system will use front and rear display indicators and the radio speakers for notification. The OBDII code sets when the object alarm module has detected the object alarm sensor supplied voltage circuit is below 7.2 volts or object alarm sensor supplied voltage circuit is above 9.2 volts.
