Folding Top Control Module
WARNING: This page is about a different car, the 2019 Buick Cascada, 2018 Buick Cascada, and 2017 Buick Cascada. However, it is still accessible from the selected car via links, so may be relevant.
The K23 Folding Top Control Module determines folding top movement by controlling the activation and direction of the hydraulic pump's electric motor based on hard-wired inputs and vehicle status information it receives via serial data. It also uses serial data to interact with other sub-systems, communicate convertible top status and position, and interface with the driver via the driver information center.
The K23 Folding Top Control Module also contains an internal thermocouple which it uses to measure the outside ambient temperature in order to take its affect on the hydraulic fluid into account. This internal thermocouple value is not accessible through serial data.
