Description:

This diagnostic trouble code (TCU 524110.08) is generated if a difference in frequency is detected between the two sensor output signals for transmission output speed. This indicates that the speed in channel 2 is lower than in channel 1, suggesting a potential issue with the B63 sensor or its circuitry.

Reaction:

When this error code is detected, the equipment may experience issues with accurate transmission output speed readings, leading to potential performance problems. The system might enter a protective mode to prevent further issues, resulting in limited operational capabilities.

Recommendations:

1. Inspect Sensor Signals:

• Verify Sensor Outputs: Compare the output signals from both channels of the B63 sensor to identify discrepancies.
• Check Sensor Alignment: Ensure the sensor is correctly aligned and installed.

2. Test the Sensor:

• Measure Frequencies: Use diagnostic tools to measure the frequencies of both channels.
• Replace if Faulty: Replace the sensor if it is providing inconsistent readings.

3. Examine Wiring and Connectors:

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

4. Verify Control Unit Functionality:

• Test Control Unit: Ensure that the control unit is correctly processing signals from both sensor channels.
• Update Software: Update the control unit software if necessary.

Note:

Maintaining the sensor and its associated circuitry is essential for accurate transmission output speed readings. Regular inspections and prompt repairs can help prevent issues related to frequency discrepancies.
