PTQ 000168.18 – Control Software, Supply Voltage (BAT) Too Low
PTQ 000168.18 (PTQ 168.18)
Code: 000168.18
Shortcode: 168.18
Description:
This diagnostic trouble code, PTQ 000168.18, indicates that the supply voltage (BAT) is below 11 volts but above 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 11 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.
