PTF 000168.03 (PTF 168.03)

Code: 000168.03

Shortcode: 168.03


This error code is triggered when the supply voltage (BAT) exceeds 16 V. Overvoltage in the battery supply can affect the normal operation of the control software.


When this code is detected, the control software may exhibit limited or no functionality.


  • Inspect Power Supply:
    • Check the battery supply to ensure it is within the specified voltage range.
    • Verify the functionality of the voltage regulator.
  • Examine Wiring and Connections:
    • Inspect all related wiring and connections for damage, loose connections, or corrosion.
    • Repair or replace as needed.
  • Monitor External Power Sources:
    • Ensure that there are no external factors contributing to the overvoltage condition.
  • Use Correct Battery Type:
    • Confirm that the battery used is appropriate for the equipment and within the recommended voltage specifications.


Proper voltage levels are essential for the control software to function correctly. Regular monitoring and maintenance of the battery and power supply system can help prevent these issues.
