Description:

This diagnostic trouble code, TSC 000168.04, is triggered when the control unit detects a supply voltage (battery) below 9 volts. Low supply voltage can be caused by a weak battery, poor electrical connections, or a malfunctioning charging system.

Reaction:

When this error occurs, the control unit may experience insufficient power to operate correctly, leading to potential malfunctions or shutdowns of the equipment.

Recommendations:

Inspect Battery:

• Check Battery Voltage:
  • Measure the battery voltage to ensure it is above 9 volts.
  • Replace the battery if it is weak or unable to maintain adequate voltage.

Inspect Charging System:

• Check Alternator:
  • Ensure the alternator is charging the battery correctly.
  • Repair or replace the alternator if it is malfunctioning.

Verify Electrical Connections:

• Check Wiring and Connectors:
  • Inspect all electrical connections between the battery, alternator, and control unit for damage, corrosion, or loose connections.
  • Repair or replace any faulty wiring and connectors.

Note:

Regular maintenance of the battery and charging system is essential to prevent low voltage conditions. Ensure all electrical components are in good working order to avoid issues with power supply.
