004 P38 Traction Control

Many off-road vehicles aren’t truly off-road because when two wheels from opposite sides are spinning the car stops and doesn’t have momentum to go forward, because the other two wheels don’t get any power. A car with Traction Control (TC) detects this situation and “brakes” the spinning wheels in order to shift power to the other wheels and these get the car moving forward.
Range Rover P38 late models have 4 wheel TC and previous models may have optional rear traction control or no TC at all.
My approach was to replace the parts needed to provide at least rear TC. My YM 1998 P38 don’t have TC because it has the ABS breaking module part no. ANR2238. Replacing this with ABS module ANR 2239 will fix this as long as the ECU module is also the right one.
To have the rear wheels TC option available (up to YM 1999) you must have: The ECU part no. ABS ECU Wabco ANR4898; The Brake Booster part no. ANR2239 (and not ANR2238).

very cool - thanks

Very good Video thx!

You know the traction control came out on the Range Rover Classic in the 1992 and beyond but you can't find any videos from back then or current ones still functioning

[@matteosini573]

Thanks a lot for your job. I have just a one doubt, are any difference beetwen anr 2839 for manual and automatic gearbox or it's the same?

What this work on the gem engines, looking at a 1997 p38a and I am sure it will only have 2 wheel traction control, I think 4 wheel was limited to the Thor engines with the bosh ecu,

[@paulnewton943]

Nice work and very informative. Do you have a simple way to activate the front tc.

[@P38Upgrades]

Sorry, but no. Just by replacing ECU and perform a more complex harness changes... not worth it for me.

Nice job on description of adding TC option. Since you have been working with this do you have a good idea of how to diagnose a p38 abs/tc error? What procedure would you follow? Thanks

[@P38Upgrades]

Once the abs and tc light were on. I did this: turn wheels totally to the left (or right). Go to the abs sensor that is located on the wheel and tap it in until stops. Repeat procedure to the other wheel and sensor. Then when you put the wheels straight the gap in the sensor is correct. Sometimes when this gap is to large the system can’t read the signal. This was the only time I had issues with ABS/TC

[@dabeatseeker8372]

hello, thank you for providing this very useful information! do u think it is possible to upgrade from a non TC car to 4 wheel TC by replacing those parts from a 4 TC car?

[@P38Upgrades]

I don't have experience on that, but from what I've searched, to get 4TC is not just about changing parts. It will need also changing harness wiring.

[@dabeatseeker8372]

@@P38Upgrades i see, well then i wont bother with 4TC. I will just buy the 2TC ECU and ABS box and hopefully its just plug and play.. thanks again for providing us with this useful upgrade!

Boa tarde companheiro, questiono, a referencia ANR2239 pode ser de um veiculo de volante a direita? uma vez que sao muito mais baratos. obrigado

[@P38Upgrades]

Boas. Penso que sim. Comprei essa peça usada e nem levantei essa questão.

[@MrTvov]

@@P38Upgrades é que no eBay, vinda do UK é uma diferença de 180€ mais barato!!

[@P38Upgrades]

@@MrTvov Tiago, comprei a minha cá em Portugal numa casa de peças usadas já lá vão uns 6 anos e paguei cerca e 50 euros.

[@P38Upgrades]

@@MrTvov em Espanha encontram-se muitos "sucateiros" (desguace) onde se conseguem peças bem baratas. p.ex. ver aqui: www.desguaces.eu

pode, são exactamente as mesmas peças.
