C2777 Code - Sensor Cluster Bus Failure
Quick Answer
The yaw rate sensor, roll rate sensor, lateral accelerometer and longitudinal accelerometer are contained in one module called the stability control sensor cluster. Common causes include Faulty Stability Control Sensor Cluster, Stability Control Sensor Cluster harness is open or shorted, Stability Control Sensor Cluster 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.

Code C2777 Description
The ABS module provides power to the sensor cluster and ground. The sensor cluster and the ABS module communicate. An open circuit or a short to power or ground on any one of these 4 circuits will cause the ABS module to set a DTC. Also, if the sensor cluster is not mounted in the correct position, with the electrical connector facing the passenger seat, the ABS module will also set DTCs.
What are the Possible Causes of the DTC C2777?
- Faulty Stability Control Sensor Cluster
- Stability Control Sensor Cluster harness is open or shorted
- Stability Control Sensor Cluster circuit poor electrical connection
