N192210460 - Service Update. Certain 2019 Cadillac CT6 equipped with engine RPO?s LSY or LTA, Chevrolet Silverado 1500 (New Model), and GMC Sierra 1500 (New Model) vehicles have a condition where the brake system control module (BSCM) may cause a service brake assist message to appear on the driver?s information center (DIC), and a service engine soon light to illuminate on the dashboard. This may cause the brake pedal feel to be different. The pedal travel will increase for normal/light braking applies. This is caused by a software issue where the motor position sensors do not correlate. Dealers will reflash the BSCM with updated software.
