The TC will still work like that but its performance will be reduced with the CDL locked. To get the best performance possible the SLABS must be updated to one programmed to use with the diff lock.

Right, I was just mentioning to Lister that no tantrum is thrown, and it works perfectly. Ideally it'd be great to go to a LR4 T/C system, but probably impossible.
I thought that was only if you turn the truck off, then on again while the diff lock is engaged.
I cut the wire to the slabs and everything works as it should. The diff lock light comes on when it should and goes off when it should. The TC is not working on different parameters either. It just doesnt come on as often because it doesnt need to.
The TC needs to work differently with the CDL than without. The 03 and 04 SLABS have the updated programming to adjust the TC to work as it should with the CDL.
Are you sure about that?
I have on an 01. It didnt come with a locking Tcase so I installed one along with a D1 linkage.
I cut the wire that tells the slabs that I have a locking Tcase. So as far as the SLABS are concerned I dont have CDL. Which means the TC works as normal. It just doesnt come on as often, because there is no need.
IF I hadnt cut the wire, then SLABS reduces the parameters.
Yeah. I know about cutting the wire, etc., but that alone doesn't make the TC perform as well as the updated SLABS in the 03 and 04. To get the most out of the TC with CDL the newer computer must be installed.
I wouldnt say it HAS to be installed. My diff lock and TC work very well together.
Personally I would like to see a side by side comparison of a truck with diff lock and and earlier SLABS vs a truck with diff lock and the 03 04 SLABS.
No it doesn't have to be installed, but the later TC is supposed to work much better as others have said above.
the 03/04 newest P/N slabs us much more effective with traction control IMO. and much less intrusive with the abs. i have run both. even from 99 to 01 the changes are noticeable.
both with and without CDL. remember 03 doesnt have cdl in some markets and does in others and has the same part.
also make sure to bleed the brakes really well manually and use good fluid, this helps a ton.

I was going to say, I would make sure your brakes are up to par first. After doing a brake job and repairing my leaky brake reservoir. I noticed a big difference in the TC.
Ive got a laundry list of things to do on the Rover.. fixing something that isnt broken isnt on that list! Maybe one day Ill mess around with it.
atriot:
If you install a later model ECU, will the traction control no longer be disabled depending on what state the lock is in when the vehicle is shut off, regardless of whether or not the wire is cut?

I'm going to fix my shit and try this. It might be cool.
Hopefully the little wiring bypass trick will sort out my amigos. If it does, I'll be able to see what an updated traction control system can accomplish. It was neat before, but nothing worth keeping around, especially since the system is inherently unreliable.
If I could have bought the vehicle without the entire system, I would have done so.
If I can get it stable for a while, and notice enough improvement with the new ECU, the system might be of some value to me. Of course, that's assuming it will even fire properly after all this time. It seems to hiccup every now and again, so I suppose it still works.
It's just got to show me that the benefits outweigh the drawbacks, of which there are many, to my mind.
Lots of wire, a computer, all those funny lines, the modulator perfectly positioned to be in my way, those dumb-ass wheel sensors, and so on... Bugs the hell out of me, but removing everything while keeping the rest of the vehicle working properly seems more difficult than I thought.
May as well see if I can make it better.

I pulled a SLABS box from an '04 DII at local boneyard this morning. I was expecting it would be part number SRD500070 but it is SRD000150, which I'd thought was the number put in '03s. I went ahead and bought it but before I install it I thought I'd ask y'all if anyone knows the differences between the two, if any. I know 500070 is looked at as the Holy Grail. It's also peculiar that what appears to be the date on the label is 11/04. I don't expect they were still making DIIs in November 2004 so perhaps this was a replacement.
I found the table below on another forum. If correct it implies that 000150 continued to be installed even after 500070 was introduced through the end of DII production.
Is it worth continuing to look for a 500070 that I can pick up inexpensively in a boneyard?
From Microcat -
Code:
Part Number From VIN To VIN
SRD100461 up to -> (V)XA227049
SRD100462 (V)XA227050 to (V)2A736339
SRD000070 (V)2A736340 to (V)2A999999
SRD000150 (V)3A000000 -> onward
SRD500070 (V)4A000001 -> onward

I'd run it. It's better than what is in the 99. Back when I had a 1999 and a 2003, I was going to but the SRD000150 in the 1999 and find a SRD500070 for the 2003. It never happened.
If you have to PAY someone to reprogram it, then maybe I'd hold off until you find the newest revision, but if you plug it in and it's got all of the correct settings for your model, then I'd just run it. I've got a nanocom, so it wouldn't matter to me. I'd run it until I found a cheap newer model, and then give that to someone at the next rally.
