CLC 000158.17 – Low Switched Supply Voltage with Engine Off. John Deere System Advisory.

CLC 000158.17 (CLC 158.17)

Code: 000158.17

Shortcode: 158.17


This code indicates that the switched supply voltage in the Cab Load Center (CLC) is below 11.2 V while the engine speed is below 512 rpm, typically when the engine is off. This could suggest a draining issue or a battery unable to maintain charge in a dormant state.


Non-critical functions might be automatically turned off to preserve battery life.


  • Battery Maintenance: Ensure the battery is in good condition and fully charged.
  • Check for Electrical Drains: Identify any devices or systems that may be draining the battery while the engine is off.
  • Battery Isolation: Consider installing a battery isolator or improving the existing setup to prevent unwanted discharge.
  • Seek Professional Assistance: If troubleshooting does not resolve the issue, professional assistance may be necessary.


Keeping the electrical system properly maintained when the engine is off is vital for ensuring the battery is ready and reliable when needed.
