Thread: Added a Sand Switch to Traction Control

Is this also applicable to D2A??? As id lke to be able to Disable the TC sometimes.

Not that I am aware of from what I have read.

The 2A has the SLABS reprogrammed to not turn off TC with CDL.

Anyone else know? Pipe in guys..

TC works on my D2a with factory fitted CDL both when engaged and disengaged.

TC is fantastic once your have a set of helical gear LSDs fitted.

Everyone has a view on ETC in sand. Having driven extensively in sand including towing in the sand with just ETC for years and then with CDL fitted and i love the 2 combined in sand. I have also used it with just CDL before the Slabs wiring mod and i have a d1 with just CDL.

Cheers

As we all know on the 1999 - 2001 Disco when you add the CDL lever it disables/reduces traction control and ABS.


:-)

Actually, no on both counts. Go for a drive on sand. It may surprise you, I have never been let down, and my D2 has gotten me out of situations my poor driving got me into. I will quote the instructions given to me with my CDL kit. Bob


": The centre diff lock is operated by pushing the right hand lever [ next to HI/LO lever] forward, when the diff lock light on the dash illuminates the diff lock is engaged, this lever can be engaged either when the vehicle is stationary, or in motion [slow] when it is engaged as above the traction control is still functional. If the engine is switched off and restarted while the diff lock is engaged the traction control will no longer operate . when the diff lock is no longer needed pull the right hand lever rearward again and when the diff lock light goes out, the diff lock has disengaged. Please note if the abs/traction control has been disabled while in diff lockthe engine will need to be switched off and restarted to enable ABS operation."


And that is exactly how I find it after quite a lot of sand driving.

^^^^^^^^what he said

I had three D2's over the years,one was a D2a,did a lot of sand driving,never had an issue with TC.

My son's Puma recently had the TC/ABS disabled due to a faulty wheel sensor,while on Fraser island.
The vehicle was hopeless in the sand compared to when the TC/ABS was working correctly.

It's the same for manual or auto, the difference is between facelift and non-facelift modells... what you want is the opposite of what the OP did cos he inserted a switch on the diff-lock switch circuit to interrupt it while the diff is locked so the SLABS ''thinks'' is not locked and keep the TC at full capacity... if you want to disable the TC you'll have to do the other way around to switch an earth to the SLABS on the diff-lock circuit to trick it that the diff is locked while it isn't and inhibit the TC...see attachment

Not speaking for you, but the D2a Tc was less aggressive than the earlier D2's, so there may be circumstances where it is not so noticeable. Having tested a 2000 D2 extensively in sand (WA) with CDL lever added, I have found in limited circumstances, that TC can be an issue. Most of the time it isn't, BUT if having to get up a long sand hill, at speed, with and uneven surface, and limited acceleration space, TC can inhibit acceleration and maintenance of momentum. This is about the only time I have had to restart the car and get rid of TC, leaving it with CDL and open diffs. Otherwise, early D2 with TC and CdL = weapon!!
