Description:

This diagnostic trouble code (TCU 524109.10) is generated if the PLC control unit reports a faulty wheel speed sensor (B84) via CAN BUS. In its active state, this fault also generates a diagnostic trouble code at the PLC, which takes priority.

Reaction:

When this error code is detected, the equipment may experience issues with accurate wheel speed readings, leading to potential performance problems. The system might display warnings or enter a protective mode to prevent further issues.

Recommendations:

1. Inspect Wheel Speed Sensor:

• Verify Fault: Check for any reported issues with the B84 wheel speed sensor as indicated by the PLC.
• Check Operation: Ensure the sensor is operating correctly and providing accurate readings.

2. Examine Wiring and Connectors:

• Inspect Wiring: Check all wiring and connectors associated with the wheel speed sensor for damage or disconnection.
• Repair or Replace: Repair or replace any faulty wiring or connectors.

3. Verify PLC Functionality:

• Test PLC: Ensure that the PLC control unit is correctly processing and transmitting signals regarding the wheel speed sensor.
• Update Software: Update the PLC software if necessary.

4. Address Related DTCs:

• Prioritize PLC Codes: Process and resolve any diagnostic trouble codes generated by the PLC, as they take priority.

Note:

Maintaining the wheel speed sensor and its associated circuitry is crucial for accurate performance. Regular inspections and prompt repairs can help prevent issues related to faulty sensor readings.
