Diagnostic Starting Point - Ultrasonic Rear Parking Assist
Begin the system diagnosis by reviewing the system Description and Operation. Refer to Object Detection Description and Operation . Reviewing the Description and Operation information will help you determine the correct symptom diagnostic procedure when a malfunction exists. Reviewing the Description and Operation information will also help you determine if the condition described by the customer is normal operation. Refer to Symptoms - Ultrasonic Rear Parking Assist in order to identify the correct procedure for diagnosing the system and where the procedure is located.
Diagnostic Trouble Code (DTC) Displaying
This vehicle is equipped with an on-board diagnostic display feature capable of displaying DTCs using the 3 indicators on the rear parking assist display. After the bulb check has been completed, the red outside indicator flashes to indicate a malfunction with the system. The module disables operation of the ultrasonic rear parking assist (URPA) system under this condition.
In order to enter the diagnostic mode, complete the following actions
- With the ignition turned OFF, short the rear parking assist diagnostic connector to ground while the vehicle is in PARK. Refer to «Object Detection Component Views»(/cadillac/srx/i-2003-2009/remont/collisionavoidance/#object-detection-system) for the location of the rear parking assist diagnostic connector.
- Turn the ignition ON.
- Place your foot on the brake.
- Shift the vehicle into REVERSE within 5 seconds. If the vehicle is not shifted into reverse within 5 seconds after turning the ignition ON, the diagnostic mode will still be initiated. However, a reverse input wiring fault will be registered as sequence #7 as shown in the Diagnostic Indicator table below. Refer to «Diagnostic Trouble Code (DTC) Clearing»(/cadillac/srx/i-2003-2009/remont/collisionavoidance/#object-detection-system__diagnostic-trouble-code-dtc-clearing) for specific steps on how to clear DTCs. After the reverse input wiring code is cleared, repeat the DTC displaying steps in order to enter the diagnostic mode.
When the diagnostic mode is first entered, the rear parking assist display displays the amber outside indicator and the red outside indicator. Then the indicators on the rear parking assist display will display one or more of the sequences in the table below to indicate where the fault exists within the rear parking assist system. Refer to Diagnostic Trouble Code (DTC) Clearing for the specific steps on how to clear diagnostic trouble codes.

Object Detection Description and Operation
The ultrasonic rear parking assist (URPA) can help a driver determine how close an object is to the rear bumper within a defined rearward field of view.
The rear parking assist display is located inside the vehicle by the rear window. Refer to Object Detection Component Views for the location of the display. The display has 3 indicators that can be seen through the rearview mirror or by turning around when seated in the driver seat.
When the ignition is ON and the vehicle is placed into reverse, the URPA performs a bulb check. During the bulb check, the 3 indicators on the display illuminate for approximately 2 seconds to indicate that the system is working. The URPA performs a bulb check and operates when the following conditions are present
- The ignition is ON
- The vehicle is placed in REVERSE (R)
- The vehicle speed is less than 5 km/h (3 mph) At speeds greater than 5 km/h (3 mph), the URPA is disable. The red indicator flashes to warn the driver that the URPA is disabled.
The URPA senses how close the vehicle is to an object. The distance is determined by the four ultrasonic sensors located on the rear bumper. When the system detects an object, one of the following will occur
- If the object is less than 0.3 m (11 in) away from the rear of the vehicle, the amber outside, amber middle, and the red outside indicators flash and the chime sounds continuously.
- If the object is less than 0.3-0.5 m (11-20 in) away from the rear of the vehicle, the amber outside, amber middle, and the red outside indicators are on and the chime sounds continuously.
- If the object is 0.5-1.0 m (20-40 in) away from the rear of the vehicle, the amber outside, and the amber middle indicators are on.
- If the object is 1.0-1.5 m (40 in to 5 ft) away from the rear of the vehicle, the amber outside indicator is on and the chime sounds one time on the first detection of an object.
URPA can detect objects 7.6 cm (3 in) wide and at least 25.4 cm (10 in) tall. It cannot detect objects above the level of the roof.
If the red indicator flashes continuously the on-board diagnostic needs to be entered to determine if a malfunction is present. Refer to Diagnostic Trouble Code (DTC) Displaying .
