HCC 000158.04 – HCC Switched Supply Voltage Low

HCC 000158.04 (HCC )

Code: 000158.04

Shortcode:

Description:

This error code is triggered when the switched supply voltage to the Hitch Control Unit (HCC) drops below 9.0 volts. This issue might be related to other 000158.XX codes present in different control units. The Vehicle Load Center (VLC) control unit wake-up circuit is the voltage source, so diagnostics for VLC codes should be performed first.

Reaction:

The HCC function is disabled (OFF) when this error code is active.

Recommendations:

  • Inspect Power Supply:
    • Check the battery voltage and ensure it is adequately charged.
    • Verify that the alternator is functioning correctly and charging the battery.
  • Examine Wiring and Connections:
    • Inspect the wiring harness for any signs of damage, loose connections, or corrosion.
    • Ensure all connectors to the Hitch Control Unit are secure and free of corrosion.
  • Diagnose VLC Codes:
    • Perform diagnostics on the VLC control unit to identify and resolve any associated issues, as the VLC wake-up circuit is a potential source of the problem.
  • Consult Technical Support:
    • If the issue persists, contact technical support for further diagnostics and troubleshooting guidance.

Note:

Ensure the electrical system is regularly maintained to prevent voltage-related issues. Keep the battery and charging system in good condition to avoid disruptions in HCC functionality.
