Code C1284 Cadillac Description

The C1284 Cadillac code indicates a malfunction in the lateral accelerometer sensor bias. This sensor is responsible for measuring the vehicle's lateral acceleration, which is the force experienced by a vehicle when turning. When this sensor is biased or not functioning properly, it can lead to inaccurate readings and affect the vehicle's stability control system. This can result in compromised handling and safety while driving. The lateral accelerometer sensor bias malfunction can be caused by issues such as sensor calibration errors, wiring problems, or sensor damage.
