    Trouble shooter codes missing for GM 4x4 trucks

    Software version 13.4

    Specifically a 2004 Chevy Silverado 4x4 Duramax came to me since there generic code reader could not access the codes for the Service 4WD system.

    C0379 and B0790 show nothing in trouble shooter for either code.

    Codes do show up on the scanner with basic description.

    C0379 Front Axle Circuit Malfunction
    B0790 Transfer Case Neutral Indicator Circuit

      I Do. I will send you a PM. The problem with posting a vin publicly is that a simple internet search can show it and possibly affect the vehicles resale's

      I Believe I checked other years and Gas truck as well and it wasn't there either.

      Not sure if it was resolved in the new 14.2 release either.
