Pajero Owners Club of South Africa

Hi Guys,

I have a technical question for which I cannot find an answer:

"CAN THE ATC BE TURNED OFF FOR A FEW DAYS WHILST TRAVELLING IN DEEP SAND?" eg: Pull a fuse (cannot find a fuse for the ATC), or is there some other means of disabling the ATC.

I (we) have done the Namib tour from Luderitz to Walvis Bay without problems except that at times it felt as if the Pajero "lost some steam". This could possibly have been as a result of the ATC trying to reduce wheel spin by reducing power.

We are going on a trip to the Khaudum shortly and I would like an answer asap.

Would it not be the ABS fuse (if one exists) because the ATC uses the ABS sensors ?

PS - I haven't bothered to go out to my car to check for myself

I've done this (thread below) a few times with good result!

Sure it wasn't the stability control?
Stability control cuts power to engine and uses abs if it thinks the car is skidding... Disable that by centre switch...
Traction control only works when there is a speed differential between wheels making the ecu assume you have a wheel in the air...

Cloyd,
Does TC really come into play if you engage the rear difflock?

On disabling the TC: there is a YouTube clip where a bunch of Aussies want to bog a Pajero down in thick sand. They achieved this by pulling the ABS relay.
I think there are a few things to learn from this:
1) a disabled TC is a good way to help you bog down in sand.
2) You can disable the TC by pulling the TC relay.

Haven't seen the clip, so just speculating here!

If they had only pulled the relay, the wheelspin is still sensed, the commands to brake and cut power will still be issued by the control system. The actual braking will not happen due to the relay being removed.

I'm pretty sure the poor old Aussies would get stuck due to the ECU cutting power!

They should have read the forum and...............pulled the plug (wheel sensor) on the entire system!

Haha.
Remember the poor Aussies actually wanted to bog down. They were conducting a body integrity type test, by yanking the stuck Pajero out in an aggressive way and then measuring the body panel gaps.

Hi, ATC doesn't cut the power, its stability control that does that and its one of the safety feature. The minute it sense that the wheel is spinning or the car is loosing control it immediately cuts the engine power. This function automatically turns off by the time you engage low range but it can be manually switched off and there is the a button in Gen 3 next to seat heating buttons.

For dunes its recommended to keep this feature off because it does effect the required power. Traction control only helps if required but does not bother the engine power at all.

Yes, yes, yes and yes.
But, there are Pajero owners that report "power loss" (I never experienced it) and there are suggestions that the two systems (SC and TC) can't be totally separated by the computers.

Wouldn't the "power loss" be the result of the ATC applying the brakes to reduce wheel speed difference?
The common advice is to disable any Traction Control in the sand because of that exact issue, except for Land Rover's Terrain Response that allows more wheel speed difference in sand mode.
Not sure how the ATC is programmed and if this advice applies or not.
