Disabling ABS while 4wdriving in a 96 Discovery TDI?

I'm not the best when it comes about D1 as i dont have one but you must be very carefull which fuse you remove cos there's a backup between them as if one blows the other one powers the ECU to trigger the warning to show you that something is wrong(there are 4 fuses, the two in the interior fusebox are for the ECU and that's where you must work)... unless you remove both main ECU powering fuses you'll have that warning which then you'll have to clear with tester or the paperclip in the obd port method... if you only want the ABS to not work you can remove either of them IMO cos the system will be disabled then...i dont know which one is the main power but maybe you can make some tests to find out

to locate the fuses see page 821-822 in the first attached document and the second shows you how to clear the fault

Rob. Here is the info that is needed to diagnose and clear faults on D1 ABS. Go to post number eight and open the PDF.

Ah, sorry. I thought you meant D2. Wasn't even aware that the D1 had ABS

Have a look at your tyres - when I first got my FL1 it had HT tyres on it and ABS would constantly activate when offroad whenever brakes were required as the tyres just slipped in the dirt.

Updated the tyres to BFG ATs and the issue just went away - driving over the same ground and ABS did not activate as the tyres were gripping better and not slipping.

For sure slam on the brakes and ABS would still activate but not in normal driving.

Yeah... running skinny M/T's (235/85/16) and it still is a PITA....

Looking at the PDF's that were posted up, it looks like there's 2 possible fuses inside the car as follows

’B’ Satellite 2
1. Electric windows - front
2. Electric windows - rear
3. Anti-lock braking
4. Central door locking
5. Electric sun roof
6. Trailer lights

’C’ Satellite 1
1. Anti-theft alarm
2. Headlight washers
3. Engine management
4. Anti-lock brakes
5. Anti-theft alarm
6. Rear air conditioning, heater

Then there's 2 in the engine bay as follows:

Fuses - spade type

1. Heated rear window
2. Sidelights
3. Air conditioning
4. Hazard warning lights, horn
5. ABS valve
6. Fuel pump
7. Fuel injectors

A Main circuit fuses - larger bolt in fuses

8. ABS pump
9. Ignition circuits
10. Lighting
11. Window lift, central door locking, rear blower
12. Heater, air conditioning
13. Generator

These 2 are for operating the Valve & Pump, so I would assume u would leave them in and just remove the 2 fuses from inside the car which would be for the ECU side of things..... Would this be correct?

From memory I did the blade fuse under the bonnet, I think it was around 30A. It brought a warning lamp up on the dash but did not activate the ABS when braking. I have read some did the fuse under the dash. I tried the one under the bonnet as it was the first one I found.

My warning light is in the ashtray...don't understand why it doesn't glow...

I agree both TC and ABS are huge PITA when on either lose gravel or soft sand. I pull out the abs/TC fuse on my d2 whenever I'm doing beach work as they will eventually stop you or push you off a cliff. The fault seems to reset itself after about the 5th time I start the car. I would highly recommend it on soft sand but not for any rock or tight gravel.

that was my thought too... cos there is the chance that by removing those to not get any fault codes like with the others

Having heard that TC was not good for sand I posed the question when doing my option B to put a switch in one of the wires. This would then log a fault and I assume it would make TC inoperative.

I was almost howled down as to why I would want to do this as every one here reckoned TC worked well in sand.
