Thread: T/C and CDL wiring.

This is the corresponding wiring diagram which shows which wire is being cut (wire to the highlighted connector input C0506-9):

And the description in the workshop manual on what will happen if the modification is not made to the pre-03 models:

I've had a debate long time ago with mr. Urban Panzer about this mod which IMO is not as good ideea as it seems on first sight cos i've done it before studying hard about this system and happened to me not once to lose motion in deep mud with locked diff and TC kicking in cos there are cases when the locked diff can come in "conflict" with the TC and work one against the other with the early SLABS ECUs hence the TC is disabled for a good reason IMO... the prove for me was that after i reconnected the wire i went through the same mud with locked diff without such problems while the TC was disabled. The "clean" way is to let it work as it was done from factory or fit an "upgraded ECU" which was removed from a facelift, that's what i did and got done with it.

That's a damn good idea. I believe I know where I can get one of those.

I always found the ETC with the D2 never liked mud. I guess this is why some argue to just let the CDL switch disable the ETC.

I did like the idea of switching the input to the SLABS so you could decide based on the conditions, but putting in a MY03 ECU would be another option.

I take it there are some extra wiring mods needed to achieve this on the pre-MY03 models.

That was going to be my next question.

The facelift SLABS ECU is plug and play wiring wise only programming is needed to addapt it to the vehicle
