Description:

This code indicates that the engine is too cold to start and is currently performing a preheat function. The engine is activating the preheater to prepare for starting. This is a normal procedure to ensure the engine starts safely in cold conditions.

Reaction:

The engine will not start until the preheat function is completed. The PDU will display a countdown indicating the time remaining until the engine can be safely started.

Recommendations:

• Wait for Preheat to Complete:
  • Allow the preheat countdown to finish before attempting to start the engine. This ensures the engine is properly warmed up and ready to start.
• Monitor the Countdown:
  • Keep an eye on the PDU display for the countdown timer. Do not attempt to start the engine until the timer reaches zero.
• Ensure Proper Preheat Function:
  • Verify that the preheat system is functioning correctly and that the engine is warming up as expected.

Note:

This is not an error code but a normal operational message. No diagnosis is needed. Regular maintenance of the engine preheater can help ensure smooth starts in cold conditions.
