Case IH 2734 (518372.11) - DEC – DEC: HST CutOff solenoid - generic/unknown error

The controller is detecting a fault in the solenoid circuit (such as an open circuit, short to ground, or short to power) but lacks the specific parameters to classify the exact electrical failure type.

• VESTRUM CVX
• Magnum AFS Series
• Farmall Compact series
• Farmall 45 HST

1. 1

   Check the transmission/DEC wiring harness for visible damage, chafing, or loose connections.

2. 2

   Test the HST Cut-Off Solenoid resistance with a multimeter to see if it falls out of specification (open or shorted coil).

3. 3

   Verify voltage and ground at the solenoid connector when the DEC commands the solenoid on.
