Seat Belt Reminder Indicators

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.

There is a driver seat belt reminder indicator located on the instrument cluster and a passenger seat belt reminder located on the overhead console. The state of the seat belt reminder indicators is determined by the RCM, which communicates over serial data with the Restraint Occupant Classification System Module (ROCSM) and the instrument cluster. The seat belt reminder indicator illuminates under the following conditions:

The RCM sends the status of the driver seat belt to the instrument cluster via serial data. The passenger seat belt status is sent to the driver information center via serial data. The rear seat belt status is sent to the driver information center via serial data. If any of the seat belts are unfastened, the instrument cluster will send a message requesting a chime sound to be turned ON after a bulb check.
