C0287 Cadillac Code - Longitudinal Acceleration Sensor Signal

Quick Answer

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. Common causes include Faulty Longitudinal Acceleration Sensor (Internal to the Inflatable Restraint Sensing and Diagnostic Module), Longitudinal Acceleration Sensor harness is open or shorted, Longitudinal Acceleration Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

What it means: C0287 Cadillac indicates Longitudinal Acceleration Sensor Signal.
Common causes: Common causes include Faulty Longitudinal Acceleration Sensor (Internal to the Inflatable Restraint Sensing and Diagnostic Module), Longitudinal Acceleration Sensor harness is open or shorted, Longitudinal Acceleration Sensor circuit poor electrical connection.
Severity: High - diagnose this code as soon as possible.

Code C0287 Cadillac 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 via serial data with the Electronic Brake Control Module (EBCM). 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 Diagnostic Trouble Code (DTC) will be set if the Longitudinal Acceleration Sensor signal is out of the specified range.
