Description:

This diagnostic trouble code (DTC) is generated when the TIA control software detects a deviation of more than 100 rpm between the engine speed and transmission input speed for at least 5 seconds. This indicates a potential problem with a speed sensor or its associated circuit.

Reaction:

Limited or no function of the control software due to the discrepancy in speed readings.

Recommendations:

Inspect Speed Sensors:

• Verify the proper operation of both the engine speed sensor and the transmission input speed sensor.
• Replace any faulty sensors that are providing incorrect speed readings.

Check Wiring and Connections:

• Inspect the wiring and connectors associated with the speed sensors for damage or disconnections.
• Repair or replace any damaged wiring or connectors.

Measure and Compare Speeds:

• Use diagnostic tools to measure and compare the engine speed and transmission input speed.
• Ensure that the readings are within the acceptable range and do not deviate by more than 100 rpm.

Update Control Software:

• Ensure that the control software is up-to-date with the latest version from the manufacturer.

Consult Technical Support:

• If the issue persists, consult technical support for further diagnostic procedures or potential hardware issues.

Note:

Regular maintenance and checks of the speed sensors and associated wiring can prevent issues related to speed discrepancies. Ensuring that sensors are properly calibrated and functioning correctly is crucial for accurate speed readings.
