What was the p/n on the replacement control unit (FDCM)?
Was it one of these?
56044199AE; 56044199AF; 56044199AG; 56044199AH; 56044199AJ; 56044199AK; 56044199AL; 56044199AM; 56044199AN; 68014199AA

If the numbers ends 129, it's for QTII
Hey Clarky,
Thanks for your tips.
Just went out and did what you suggested.......turned the ignition on (not starting), unplugged the wiring to the newly installed TCCU, plugged it back in. The 'Service 4WD System' is still there.
See photo below of the new unit. If you cant read the numbers properly, it reads P56044199AJ.
BTW: Tim at Poly 4x4 checked my VIN number prior to selling me the module.


Keen to know your thoughts, Craig
