Distance Sensing Cruise Control Module Learn Procedure: Notes

WARNING: This page is about a different car, the 2015 Buick LaCrosse. However, it is still accessible from the selected car via links, so may be relevant.

After replacing and programming the K14 Distance Sensing Cruise Control Module, it is necessary to perform a learn procedure to align the radar. This is indicated to the technician by DTC C056E 4B. The learn procedure is performed while driving the vehicle with the scan tool connected. The learn procedure is initialized using a scan tool and the scan tool must remain connected until the learn procedure is complete. During this time a Vehicle Ahead tell-tale will be displayed on the Instrument Panel Cluster (IPC) and it will flash. Once the learn procedure is complete, the Vehicle Ahead tell-tale on the IPC will turn off.

If the learn procedure is not successful, it could be due to an improper driving environment, a module and bracket assembly bent out of position or an incorrect module mounting. A typical driving environment is usually sufficient to learn the module within 10-30 minutes.
