New Holland Diagnostic 'H' Routines

New Holland TN series tractors have a built in diagnostic system that is accessed by using the New Holland diagnostic test switch, Tool No. Tool No. 4FT 950. This cable sets the instrument cluster into 'H' menu diagnostic mode to troubleshoot directly on the tractor without supplemental diagnostic software.

Some New Holland dealers are saying this cable is no longer available so we've received a number of calls asking about the TEXA equivalent - TEXA New Holland Diagnosis Button Cable for TM 2nd Series.

The TEXA cable works exactly like the OEM cable, you don't need to have a TEXA diagnostic tool to access the H Menu. Once connected the tractor will display HH on the instrument cluster and you will have a number of tests and calibrations that can be performed. When you purchase the TEXA cable we include a 35 page manual showing all the tests and calibrations available through the H menu.
