Description:

This diagnostic trouble code, PTQ 000168.01, indicates that the supply voltage (BAT) is below 9 volts. This condition may suggest a weak battery or other electrical issues affecting the power supply to the control software.

Reaction:

When this error is detected, the control software may experience limited or no functionality, affecting the overall performance and drivability of the tractor.

Recommendations:

Check Battery Health:

• Test the battery voltage and overall health using a multimeter or battery tester.
• Replace the battery if it is found to be weak or failing.

Inspect Battery Connections:

• Ensure all battery connections are secure and free of corrosion.
• Clean and tighten any loose or corroded connections.

Verify Charging System:

• Test the alternator and charging system to ensure it is providing adequate voltage to the battery.
• Repair or replace any components of the charging system that are not functioning correctly.

Monitor System Voltage:

• After addressing the above steps, monitor the system voltage to ensure it remains above 9 volts during operation.
• Confirm that the control software is receiving sufficient voltage for proper functionality.

Note:

• Regular maintenance of the battery and charging system is crucial to prevent low voltage issues.
• If the problem persists despite taking the above measures, consult technical support or the manufacturer for further assistance. It may indicate a deeper electrical system issue.
