The Super Cruise driver assistance feature (RPO UKL) on 2022 Tahoe, Suburban, Yukon; and 2022-2023 Escalade models uses front short-range radar to allow Super Cruise to perform lane-change maneuvers.
When performing repairs or following diagnostic procedures, there may be a misunderstanding about the vehicle’s options since vehicles built with RPO 00U and/or RPO 02O are not equipped with Super Cruise and do not include the front short-range radar modules, but the front bumper/fascia does include the connectors and wiring for the front short-range radar modules. On vehicles not equipped with Super Cruise, module jumper/bypass connectors should be installed in place of the front short-range radar modules. (Fig. 6)

In some cases, there may be a concern about whether the vehicle should or should not have the front short-range radar modules. For example, the front short-range radar modules may have been installed during collision repairs on vehicles not equipped with Super Cruise. As a result, DTC U3000 sym 95 (Control Module Incorrect Assembly) may have set.
If the front short-range radar modules have been installed on a vehicle (Fig. 7) when they should not have been, the modules will need to be removed and the module jumper/bypass connectors should be installed to complete/connect the CAN Bus 8 communication loop.
