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 bumper. The object detection system will notify the driver when backing up at speeds less than 8 km/h (5 mph), which make parking easier and helps you avoid colliding with objects such as parked vehicles. The object detection system will use the rear display indicators and the radio speakers for notification.

Object Detection Description and Operation

Electrical Information Reference

1. Ignition OFF, disconnect the harness connector at the object alarm module.
2. Ignition ON, with the telltale assembly supply voltage circuit connected to B+, verify that each telltale assembly indicator illuminates when each indicator control circuit terminal(s) B, C and D is connected to ground.

⇒	If one or two indicators of the telltale assembly does not illuminate, test the control circuit(s) for a short to ground or an open/high resistance. If the circuit(s) test normal, replace the telltale assembly information center.

⇒	If all the indicators of the telltale assembly does not illuminate, test the supply voltage circuit for a short to ground or an open/high resistance. If the circuit(s) test normal, replace the telltale assembly information center.

3. If all circuits test normal, test or replace the rear object alarm module.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
