Description:

This diagnostic trouble code (DTC), SSU 523826.01, is triggered when the voltage at the signal line of channel 1 of the wheel angle sensor (WAS) falls below 0.5 volts for longer than 320 milliseconds. This indicates a low voltage condition, potentially due to an open circuit in channel 1 of the steering angle sensor.

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 channel 1 of the wheel angle sensor (WAS) for proper voltage regulation.
• Ensure that the voltage does not fall below 0.5 volts.

Verify Sensor Connections:

• Inspect the wiring and connectors related to channel 1 of the wheel angle sensor for signs of damage, loose connections, or corrosion.
• Ensure all connections are secure and free from contaminants.

Check for Open Circuits:

• Use diagnostic tools to check for continuity in the power supply circuit to ensure there are no open connections.

Update Software:

• Ensure that the SSU software 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 in channel 1 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.
• Ensuring the electrical system is properly regulated can avoid interruptions in sensor operation.
