Code B2741 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 B2741?
- Faulty Stability Control Sensor Cluster
- Stability Control Sensor Cluster harness is open or shorted
- Stability Control Sensor Cluster circuit poor electrical connection
How to Fix the DTC B2741?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
