Description:

This fault code indicates that the hand throttle sensor CAN data is missing or the update rate is abnormal. This could be due to issues with the throttle sensor, CAN system, or programming control units.

Reaction:

When this error is detected, the equipment may experience throttle control issues, potentially leading to poor engine performance or unstable speed regulation. The system might enter a safe mode to prevent damage.

Recommendations:

Inspect Hand Throttle (P03) Without ECU:

• Check the hand throttle for proper operation.
• Ensure the throttle is not damaged and is correctly positioned.

CAN System Diagnosis:

• Perform a thorough diagnosis of the CAN system.
• Check for any communication errors, faulty nodes, or wiring issues.
• Repair or replace any faulty components.

Programming Control Units:

• Ensure all control units are correctly programmed.
• Reprogram the units if necessary to restore proper communication and functionality.

Update Control Software:

• Make sure the control unit software is up-to-date with the latest fixes and improvements.

Consult Technical Support:

• If the issue persists, seek assistance from technical support for further diagnostics and potential sensor replacement.

Monitor System Performance:

• After implementing the corrections, monitor the throttle system to ensure normal operation and that the fault does not recur.

Note:

Regular inspection and maintenance of the CAN system and throttle sensor can help avoid such faults. Environmental factors such as electromagnetic interference can also affect CAN communication, so consider these factors when troubleshooting.
