Description:

This diagnostic trouble code (DTC), SSU 001079.04, is triggered if the power supply for the wheel angle sensor (WAS) drops below 4.75 volts for longer than 320 milliseconds. This indicates that the circuit may be open or experiencing a low voltage condition.

Reaction:

When this error is detected, the steering system may not function correctly, potentially leading to inaccurate steering angle readings and compromised vehicle control.

Recommendations:

Inspect Power Supply:

• Check the power supply to the wheel angle sensor for proper voltage regulation.
• Ensure that the voltage does not drop below 4.75 volts.

Verify Sensor Connections:

• Inspect the wiring and connectors related to the wheel angle sensor for signs of damage, loose connections, or corrosion.
• Ensure all connections are secure and free from contaminants.

Update Software:

• Ensure that the software related to the steering system is up-to-date. Apply any available firmware updates to improve system performance and compatibility.

Replace Faulty Components:

• If the wheel angle sensor or related components are found to be defective, replace them with new, genuine parts.

Consult Technical Support:

• If the error persists after performing the above steps, consult technical support or the manufacturer for further assistance.

Note:

• Regular maintenance and inspection of the steering system components can help prevent low voltage conditions.
• Ensure the electrical system is properly regulated to avoid interruptions in sensor operation.
