Recommendations:

Power Cycle the System:

Turn off the ignition and restart the system to see if the issue resolves itself upon reinitialization.

Check Control Unit Load:

Ensure the control unit is not overloaded with tasks. Reduce the load by disabling any unnecessary functions or features temporarily.

Update Control Unit Software:

Ensure the control unit is running the latest software version. Update the software if necessary to address potential timing issues.

Inspect Control Unit Cooling:

Check that the control unit is adequately cooled and not overheating, as excessive heat can cause timing issues. Ensure proper ventilation and cooling mechanisms are in place.

Replace Control Unit:

If the issue persists and cannot be resolved through the above steps, consider replacing the control unit with a new one.

Note:

Maintaining the control unit and ensuring it operates within its intended parameters can help prevent watchdog timer issues. Regular updates and proper cooling are essential for optimal performance.
