Description:

This diagnostic trouble code, RPT 000190.09, is generated when there is a data transfer problem between the RPT control software and the ECU (Engine Control Unit) control software. The issue arises when the RPT control software intermittently or completely fails to receive one, several, or all of the expected CAN messages. This problem can indicate an issue with the CAN bus, the transmitting control software, or engine stalling.

Reaction:

When this error is detected, the functionality of the control software is significantly limited or entirely non-functional. This affects the overall performance of the equipment, leading to reduced efficiency or operational capability.

Recommendations:

Inspect CAN Bus Wiring and Connections:

• Check all wiring and connections associated with the CAN bus for signs of damage, corrosion, or loose connections.
• Secure any loose wires and repair or replace damaged components as necessary.

Verify CAN Bus Communication:

• Use diagnostic tools to test the CAN bus communication for any irregularities or failures.
• Ensure that all CAN messages are being correctly transmitted and received between the RPT control software and the ECU control software.

Check for Engine Stalling:

• Investigate if engine stalling is occurring, as this can cause intermittent or non-existent CAN messages.
• Address any issues related to engine stalling, such as fuel supply or ignition problems.

Update Control Software:

• Ensure that both the RPT and ECU control software are updated to the latest versions.
• Install any available patches or updates that address CAN bus communication issues.

Consult Technical Support:

• If the problem persists after initial troubleshooting, consult with technical support or the equipment manufacturer for further assistance.
• Provide detailed information about the issue, including any error logs or diagnostic reports.

Monitor System Performance:

• After performing the recommended actions, monitor the system for any recurrence of the issue.
• Keep detailed records of any further errors or irregularities to assist in ongoing troubleshooting.

Note:

Intermittent reception issues on the CAN bus are often caused by loose wires, poor connections, or engine stalling. Regular maintenance and inspections of the CAN bus system and the engine can help prevent such issues. Ensuring that all software is up-to-date can also mitigate many communication-related problems.
