Hi!
I have a question to see if someone can help!
I have a 1996 p38 2.5 dse (diesel)....as you know It didnt come with ETC (electronic traction control) and it did come with LSD (limitid slip central locking diferential). my cuestion is.....as the car has got ABS and everything else is the same as the latter model that did come with ETC.....Can I make mine to be with Electronic traction control?
Previous model of the classic did come with ETC because they came with ABS....so it has something to do with it.
The first models of the p38 didnt come with ETC....
I would like to fit ETC to mine (as it would help a little more because the central diferential is limited slip) If its posibble?
Hope someone know something about this ore could investigate their later models to see if the system is controlled with a different ECU ore what ever!
Thanks!

Well. according to my copy of the ETM (Electrical Troubleshooting Manual) in Rave, all models have traction control. I think the only difference was that pre 1999, it was on the rear wheels only and post 1999 it was on all four wheels. When you initially switch on the ignition, you should get three warning lights grouped together in the lower left hand side of the instrument panel - Handbrake/Brake System (Red), ABS (Yellow) & Traction Control (a 'T' surrounded by a dotted line) (Amber). Do you not get this third one?
 
Pre-99 had the option of traction control on the rear wheels, post-99 had the option (may have been standard) of all 4-wheels traction control.

I believe you are thinking along the correct lines, and I reckon if you swapped the ABS ECU over to one that has the traction control then it might work? I'm pretty sure its not a case of checking a box via Testbook.

I had ETC on my Classic, but I don't miss it on the diesel as it doesn't have enough power to spin the wheels! If you are venturing off-road however it would be a definite benefit.

Post '99 TC was standard on all 4 wheels, and as you say optional 2 wheel pre-'99. However although it should be possible to add TC to non-equiped pre-'99 cars you can only do it to rear wheels as the 4 wheel ECU uses a different loom and connectors. Also the TC equiped cars had a different ABS valve block that contains additional valves so you'd need to add that too. Unless you can get the bits at bargain prices it all starts to look rather pricey, and might be better value to go for rear locking diff instead.
 
It makes sence all that you say! I have read the rave manual and it didnt say it was optional..but fair enough!
Mine doesnt seem to have it then! Because no light when key turned!
I could think on a rear locinkd differencial....the thing is I dont want it for serious offroading...only when I go about....For serious offroading I have a Range classic 2-door fairly well restuared with a 3.5 v8 with edelbrock intake manifold and carb and an autobox (the torqueflite A-727).
Thanks for the help!

Bugger me I stand corrected again. I always thought it was a standard fit. Cheers lanmjdun

So did I when I first started shopping for a p38, then I discovered the original buyers of P38's where mostly posers and upgraded base models with wood and leather, but didn't bother with useful things like TC that no-one would see.
 
How often are you really going to need traction control on a 4wd big tyred and underpowered motor anyway?

P38 TC is aimed much more at off road than modern interpretations of TC which are more stability controls than true traction control (they control traction by cutting power not by actively braking the spinning wheel the way the P38 does).
The P38 TC is meant as a substitute to diff locks not to stop wheel spin at the lights.
 
According to RAVE, engine power is reduced when traction control operates, it certainly is with the Diesel ECU. Give me a LSD anytime, activating the brake on the slipping wheel is just a cheap alternative that wastes energy.
