Code C1281 GMC Description

The C1281 GMC diagnostic trouble code (DTC) indicates that the vehicle's Vehicle Stability Enhancement System (VSES) sensors are uncorrelated. The VSES system is responsible for helping to maintain stability and control of the vehicle by detecting and mitigating skidding or loss of traction. When the sensors within the system are not providing consistent data or are not in agreement with each other, it can compromise the effectiveness of the VSES system, potentially leading to decreased vehicle stability and increased risk of accidents.
