Details of the c1555 OBD Code
Code C1555 relates to an issue with the steering angle sensor on the vehicle.
OBD code C1555 means Steering Wheel Angle Sensor Circuit Failure.
This code is triggered by the Electronic Stability Control (ESC) module when it detects a fault in the steering wheel angle sensor circuit.
The steering wheel angle sensor is responsible for providing data on the position of the steering wheel to the ESC module, allowing it to assist in vehicle stability control.
When a circuit failure is detected in this sensor, the C1555 code is set, indicating a problem with the steering wheel angle sensor system.
Mechanic’s Tech Notes
Code C1555 indicates a steering angle sensor internal fault on the vehicle.
OBDII code C1555 typically indicates a communication error between the transmission control module (TCM) and the engine control module (ECM).
To diagnose this, check TCM power and ground using a multimeter.
Use a scan tool to confirm if the TCM communicates over the Controller Area Network (CAN) network.
Inspect wiring harnesses and connectors for damage, and ensure connector pins are intact and free of corrosion.
If no visible issues are found, consider reprogramming or reflashing the TCM.
