Description:

This diagnostic trouble code (DTC) is generated when the control software detects that too much time has elapsed (watchdog timeout). The watchdog timer is a safety mechanism that resets the system if the software fails to respond within a specified time frame.

Reaction:

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

Recommendations:

Verify Software Operation:

• Ensure that the control software is running efficiently without any delays or hang-ups.
• Restart the control software to reset the watchdog timer.

Update Control Software:

• Ensure the control software is up-to-date with the latest version provided by the manufacturer.
• Updates may include improvements or fixes for timing and response issues.

Inspect System Load:

• Check for any excessive system load that may cause the software to lag.
• Reduce unnecessary processes running on the control unit to optimize performance.

Consult Technical Support:

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

Note:

Regular maintenance and software updates can prevent watchdog timeout issues. Ensuring the system is free from excessive load and running efficiently is essential for optimal performance.
