Code C1250 2017 Chevrolet Silverado Description

The Yaw Rate, Lateral Acceleration, and Longitudinal Acceleration Sensors are combined into one Multi-Axis Acceleration Sensor, internal to the Inflatable Restraint Sensing and Diagnostic Module. The Multi-Axis Acceleration Sensor communicates with the Electronic Brake Control Module (EBCM) and Transmission Control Module (TCM) via serial data. The Electronic Brake Control Module activates the stability control function depending on the Multi-Axis Acceleration Sensor input. The Inflatable Restraint Sensing and Diagnostic Module uses the Multi-Axis Acceleration Sensor to determine if the vehicle is in a rollover or near collision incident. The Transmission Control Module sets this Diagnostic Trouble Code (DTC)s. The DTC will be set when the Transmission Control Module detects a fault that prevents it from performing a hill hold function.
