A Side Detection System Temporarily Unavailable message may be displayed on the instrument cluster of some 2024 Silverado 2500 HD/3500 HD and Sierra 2500HD/3500 HD trucks. There also may be false alerts or the system may operate erratically or not at all. These conditions may be caused by a decal attached to the radar-emitting side of one or both of the Side Obstacle Detection Modules. (Fig. 18)

The supplier-installed part label that is attached to the non-radar emitting side of the module is not an issue and does not cause any interference or blockage of the radar. (Fig. 19)

Any decals or stickers that are attached to the radar-emitting side of the Side Obstacle Detection Module can cause interference or blockage of the radar and must be removed. The Side Obstacle Detection Modules are attached to the rear bumper impact bar brackets. (Fig. 20) Once the decal is removed from the module and the vehicle is driven, the Side Obstacle Detection Modules will automatically learn the blockage has been removed and return to normal operation.
