Please I'm looking for object detection control module p/n. All data called the code - UFT (Object Detection Description and Operation).

There is operation :
The side blind zone alert (SBZA) system is designed to detect vehicles or other objects that may be located in the vehicles blind spots. This detection is performed by two side object sensors, located behind the rear fascia on each side of the vehicle. When an object is detected in a blind spot, an indicator in the outside rearview mirror will illuminate, notifying the driver that it is unsafe to change lanes.

The SBZA system is made up of the following components:

Left side object sensor
Right side object sensor
Driver door module
Front passenger door module
Driver outside rearview mirror
Passenger outside rearview mirror

Side Object Sensors

The side object sensors are each located behind the rear fascia, positioned so that the sensor is pointing out toward the opposite lane. Each sensor is supplied B+ and ground. The right sensor receives an additional ground. Both sensors communicate independently on the serial data line. The serial data enters the right sensor in a pass-thru configuration, that connects to the left sensor. The scan tool is able to individually communicate with each sensor.

When a vehicle or object is detected by a side object sensor, a serial data message is sent to the appropriate door module to illuminate the indicator located in the outside rearview mirror.

Door Modules

The driver and passenger door modules receive serial data messages from the side object sensors. When a message is received indicating that a vehicle or object is in the blind spot, the appropriate door module will apply voltage to the indicator located in the outside rearview mirror, illuminating the indicator. The door module provides a continuous low reference circuit for the indicator.

Outside Rearview Mirror

The outside rearview mirrors each contain an indicator that is controlled by the appropriate door module. This indicator is illuminated when a vehicle or object is positioned in the vehicle's blind spot.

Side Blind Zone Alert Operation

When the vehicle is started, the indicators located in the outside rearview mirror will briefly illuminate to indicate that the system is operating. The side object sensors cover a zone of approximately one lane over from both sides of the vehicle, 11 ft. or 3.5 m. This zone starts at each side mirror and goes back approximately 16 ft. (5.0 m). The height of the zone is approximately between 1.5 ft. (0.5 m) and 6 ft. (2.0 m) off the ground. When a vehicle or object is detected in this area, the appropriate indicator will be illuminated, indicating to the driver that it is unsafe to change lanes. If a turn signal is activated while the indicator is illuminated, the indicator will flash as a more urgent warning that a lane change may be unsafe.

Foul weather may affect the operation of the SBZA system. Occasional missed alerts can occur under normal circumstances and will increase in wet conditions. The number of missed alerts will increase with increased rainfall or road spray. Heavy rainfall, as well as mud, dirt, snow, ice, or slush build-up on the rear fascia, will completely disable the system.

If the vehicle is towing a trailer or has an object, such as a bicycle rack, attached to the rear of the vehicle, the SBZA system may not function properly and the indicators will remain illuminated at all time.

Side Blind Zone Alert DIC Messages

SIDE BLIND ZONE ALERT SYSTEM OFF

This message indicates that the system has been disabled through the DIC. Refer to the vehicle owners manual for instructions on how to set personalization options on the DIC.

SIDE BLIND ZONE SYSTEM UNAVAILABLE

This message indicates that the system has been disabled because the sensor is blocked or can otherwise not accurately detect vehicles or objects. Such instances may be mud, dirt, snow, ice, or slush build-up on the rear fascia, heavy rainfall, or excessive road spray.

SERVICE SIDE BLIND ZONE ALERT SYSTEM

This message indicates that the system requires service. When the message is displayed, the indicators will remain illuminated at all times, notifying the driver that the SBZA system should not be relied upon when changing lanes.

Please help.

From what this schematic shows the sensors are the modules p/n 20823460 shows you need 2 and these communicate with both driver and passenger window switches to illuminate the light on the mirrors.. Disclaimer...Be sure to double check that p/n with the dealer to make sure it will work for your vehicle, also a tec 2 scanner may take you right to the problem

Hi,
They did scan and so scanner no communication with Right side object detection control module. As I reading there are located in the doors passenger and driver. See my first post.

"Door Modules

The driver and passenger door modules receive serial data messages from the side object sensors. When a message is received indicating that a vehicle or object is in the blind spot, the appropriate door module will apply voltage to the indicator located in the outside rearview mirror, illuminating the indicator. The door module provides a continuous low reference circuit for the indicator."

So my question is, are window switches is module?

I gather some information about the window switches, that they are different GM "reference number" (I'm no sure about the term)
Door switch:
1.X1
2. X2,
3. X3,
4. X4(KA1 or AN3 without KB6
5. X7, but for driver door X7(DL3 or DR4)

Whenever this means. The sensors are working, since yesterday was lots snow and drove, parking assist went off mode, but bumper round sensors were clean, but soon as I clean right/left bumper surfaces, parking assist went back to normal operation condition.

Thanks

communication is a tough one, it could be the right side door module, the wiring to the sensor or the sensor which is located on the passenger side behind the bumper cover just rear of the tire, if the problem arises i would start there I'm sure its pretty dirty in there being behind the tire

yes it's true. I think will try to find used door/window switch with blind module and replace it. it's look easy just pop all thing out. I hope module is the window/door switch. I might ask Chevy dealer again.
