Code: 000168.04

Shortcode: 168.04

Description:

This diagnostic trouble code (DTC), SSU 000168.04, is triggered if the battery voltage drops below 9 volts for longer than 320 milliseconds. This indicates an undervoltage condition that can affect the performance and reliability of the equipment’s electrical systems.

Reaction:

When this error is detected, the equipment may experience reduced functionality or fail to start. Critical systems may not operate correctly, leading to potential safety and operational issues.

Recommendations:

Inspect Battery:

  • Check the battery for signs of damage or low charge. Charge or replace the battery if necessary.

Examine Charging System:

  • Ensure the alternator and voltage regulator are functioning properly to maintain adequate battery voltage.

Verify Electrical Connections:

  • Inspect wiring and connectors for any signs of damage, loose connections, or corrosion.
  • Ensure all electrical connections are secure and free of contaminants.

Monitor Voltage Levels:

  • Use diagnostic tools to monitor system voltage and ensure it remains within the acceptable range.

Consult Technical Support:

  • If the error persists after performing the above steps, consult technical support or the manufacturer for further assistance in identifying and resolving the issue.

Note:

  • Regular maintenance of the battery and charging system can help prevent undervoltage conditions.
