Hi, bought a 1997 dse auto. As far as I can tell there is no t/c. I know on this age it's only on the rear but I don't think mine has it. How can I tell? There is a 1/10 second flicker of the t/c light on the dash on start up but that's it. If I don't have it can I retro fit it ? I'm just worried about getting stuck in the snow and ice.
P38 retro fit traction control ?

They all came with Traction Control....
Earlier models on Rear only, then later models on all 4 wheels....
Yours will have T/C....
Find a large flat empty space with loose topping (Gravel, Snow, Ice) and boot it to try and get the back wheels to spin, the T/C light will flicker when it is cutting in.

If it,s a DSE i think it should have rear wheel TC. Get the codes read. TC lamp should come on then go out after it does it's self check. You won't get stuck without it i don't think.

Not all P38a's have TC. Mine (1995 basic spec DT) sure doesn't have it, and it also doesn't have the TC lamp.
BUT, if it has the TC lamp, it should also have the TC.

Saint, i did also think so, when i bought it then, the bitter disappointment. Still, i haven't yet been in a situation where i'd need it, the wheels just don't want to slip no matter what i do. Sticky winter tires probably help
I guess it's just one less thing to go wrong with the car...

My 4.0 se doesn't have it. could a specialist turn it on in the ecu? Or could i buy an Abs/traction controle ecu off a hse and plug that in, instead of my abs ecu?

AFAIK you need to upgrade brake/abs/tc ECU and brake modulator, but i could be wrong... i've been looking to do the same on my 2.5 DT. In the end, true-trac diff could be the best option.

i don't want to spend much money on mine thats the trouble though. but i would like to green lane it every once in a while. I checked my dash clocks to see if the bulb was there and it is. So i just wondered if i is a case of having it turned on within the ecu. You can pick ecu's up for 25 quid off e-bay. i might have a bid and try, i can always sell it on again.

You can check your modulator for stamped-on product number, regarding to the rangerovers.net they are:
STC 2779 No Traction Control
STC 2778 Two Wheel Traction control
SXC 100010 Four Wheel Traction Control
Voguese, the loom and the units should be the same type between the '95 and '99, its the post '99 4 wheel TC that are different.

There only seems to be two different ecu's, both look to have same plugs on them. i am going to have a look at mine tomorrow and see which i have. manufacturers tend to just use a loom that does everything thats why there are loads of spare plugs tucked away everywhere for all the add ones you can get.

There are actually 3 types of ABS ECU as well as the 3 types of modulator mentioned:-
ANR 1250 No Traction Control
ANR 4898 Two Wheel Traction control
SRD 100501 Four Wheel Traction Control
Change over to two wheel TC was from WA410482
Change over to four wheel TC was from 99 model year all models.
Obviously the correct ECU and modulator must go together.
A number of people have looked at fitting the later four wheel TC units. Never heard of anyone doing it successfully.

So if i get an ANR2239 (modulator with 2 wheel traction) and an ANR4898 (ecu) should it plug and play or is it just going to beep at me and throw several messages up on the dash? Has anyone any idea? My car is a 1996 so i an only after the 2 wheel traction.
Another question, is there a centre diff lock on the auto box? Because it would only need to loose traction on one wheel to come to a complete stop otherwise.

The central diff lock is an integral part of the transfer box, which is the same for both auto and manual gearbox equipped cars. The transfer box has a double role. First one is changing between high and low gear, and the second is acting as a central differential. The viscous coupling is then used to detect difference in speed between front and rear driveshaft, and lock the central diff if the difference is big.
