Servotronic Steering Function

The Servotronic control module works with the vehicle’s steering system to adjust power-steering assistance based on vehicle speed.

At lower speeds, the system can provide greater steering assistance for easier maneuvering. At higher speeds, steering assistance is reduced to provide a more controlled steering feel.

A faulty control module or relay may contribute to:

• Heavy or inconsistent steering assistance
• Steering assistance that does not change correctly with speed
• Intermittent Servotronic operation
• Steering system electrical faults
• Warning lights or stored diagnostic faults
• Changes in steering feel

Before replacing the module, the complete Servotronic system should be diagnosed because wiring, connectors, the steering system, or other components can also cause similar symptoms.
