Description:

This diagnostic trouble code (DTC) is generated when the PTA control software and the PLC control software do not register any transmission output speed and cannot provide the CAN BUS with any data. A transmitted replacement value generates this DTC in the TIA control software. This issue also generates a corresponding DTC in the PTA control software, taking priority.

Reaction:

Limited or no function of the control software, impacting vehicle performance and diagnostics.

Recommendations:

Inspect Transmission Output Speed Sensors:

• Verify the proper operation of the transmission output speed sensors.
• Replace any faulty sensors that are not providing accurate readings.

Check CAN BUS Communication:

• Inspect the CAN BUS wiring and connections for any signs of damage, corrosion, or loose connections.
• Repair or replace any faulty wiring or connectors.

Verify Control Software Synchronization:

• Ensure that the PTA and PLC control software are correctly synchronized and updated to the latest versions provided by the manufacturer.

Monitor CAN BUS Traffic:

• Use a CAN BUS analyzer to monitor traffic and identify any sources of incorrect messages or high error rates.
• Address any identified issues such as faulty control units or devices on the network.

Consult Technical Support:

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

Note:

Regular inspection and maintenance of the CAN BUS network and related sensors can prevent communication errors. Ensuring all devices on the network are functioning correctly and within specifications is crucial for reliable operation.
