Cadillac Cruise Control Needs Sensor Reboot
This bulletin applies to 2013-2019 Cadillac ATS, 2014-2019 CTS, 2013-2016 SRX and 2013-2019 XTS vehicles. A customer may see an “Adaptive Cruise Temporarily Unavailable” message when attempting to activate cruise control. Other possible messages might include Park Assist Symbols Unavailable, Lane Departure Warning Unavailable and Rear Auto Braking Unavailable.
If normal diagnostics lead to a concern that can be duplicated and there are no diagnostic trouble codes (DTCs) present, perform the yaw rate sensor learn procedure (multi-axis sensor), clear any DTCs that may have been set during programming and let the vehicle go to sleep before evaluating the concern.
For “Adaptive Cruise Temporarily Unavailable” only, the majority of concerns will be resolved by performing the multi-axis sensor learn. If the concern has not been resolved, perform the Long Range Radar Learn called out in the radar sensor module – Long Range Programming and Setup procedure in-service information.
