Code 25
Short detected in Field Current Circuit

Possible Causes:
- check cables from field windings to field wiring assy
- check cables from field wiring assy to H-bridge control module
- check cables from H-bridge control module to vehicle manager
- check cables from field waring assy T1 - T4 (base leads for TM1 and TM2)
- the field wiring assy (tm1 or tm2 may be bad
- H-bridge control module may be bad
- vehicle manager may be bad
- the motor may have an internal short

I would check the drive motor first of all and all the cables in its circuit.
