UIM 000168.04 – Supply Voltage (ELX) Too Low

UIM 000168.04 (UIM 168.04)

Code: 000168.04

Shortcode: 168.04

Description:

This diagnostic trouble code is triggered when the system voltage (ELX) drops below 10.0 volts for more than 5 seconds. This condition suggests that the electrical system is experiencing lower than normal voltage levels, which can affect the performance of various components.

Reaction:

When this code is detected, the equipment may experience reduced performance or malfunctioning of electronic components. Critical systems may enter a protective mode or shut down to prevent damage.

Recommendations:

Inspect Battery:

  • Check the battery for charge and condition. Ensure it is fully charged and capable of holding a charge. Replace the battery if it is faulty or aged.

Inspect Alternator:

  • Verify that the alternator is functioning correctly and producing the required voltage output. Repair or replace the alternator if it is defective.

Check Electrical Connections:

  • Inspect all electrical connections for signs of corrosion, looseness, or damage. Ensure all connections are clean, tight, and secure.

Monitor Voltage Levels:

  • Use a multimeter to monitor the system voltage during operation and record any drops. This can help in diagnosing intermittent issues.

Consult Technical Support:

  • If the issue persists, consult technical support or the manufacturer for further assistance in diagnosing and resolving the problem.

Note:

Low voltage conditions can lead to malfunctioning of sensors, control modules, and other electrical components. Prompt attention to this issue is necessary to avoid extensive damage. Regular maintenance and inspection of the electrical system are essential to prevent such problems.
