Disabling ASTC on 2013+ MN's

[ag9111]

Has anybody worked out how to disable the ASTC on the upgraded 2013+ Tritons.

I know on earlier models you could pull the relays but mine doesn't come with relays.

I tried pulling the feed fuse, fuse 15, but this killed the whole car and now I have an airbag light

Open circuiting one of the wheel sensors will disable the ASTC but it will also cause a code that I don't know if I can clear it.

Diff lock, reverse and stop switch are all incorporated into the ASTC so there might be a way there. I know the diff lock signal will not register a code until over 10kph.

Anyway, heading to Fraser in 2 months for 10 days so I would like to sort this pretty soon

speaking of newer MN's... have MMAL incorporated the TC to work with the DL on yet? if not, has somebody else done this yet? just thought it might be useful for you ag....

i assume your looking to disable traction control as well as stability control here...

[ag9111]

Yep
want to kill TC and ASC

[NowForThe5th]

You have the factory rear locker, Garth? TC disengages when locker is on so (and I'm thinking out loud here) if the car thought that the RDL was engaged that might be a starting point.

For ASC you can always push the switch but that's a pain every time you restart the vehicle. So, a switch that enables a momentary closing of the ASC switch wires when the ignition is turned on would work for this.

The Pajero guys have a number of threads on related things but mainly aimed at having the TC on with the RDL to mimic a front locker. Still, the systems are similar and there may be some clues there.

does the system get disabled in low range?
might be another source of "tricking" the system?

it is a real pain in other vehicles in the sand (use quite a lot of different types and ALL the newer ones have this as standard) the only way to disable in stuff like hilux, ranger, prado and Isuzu is low range?

I have done this. 2013 mm triton without the diff lock option. I'm not telling you to do it but if your were going to do it this one way it can be done . After looking at the wiring schematics I wired in a toggle switch that when flicked, turns off ASC, TC and ABS. If you don't want to wire in a switch it is a simple case of getting a short (60mm or so) wire with small male terminals on each end and looping it on the plug that usually plugs into the diff lock when optioned. There are 2 spare plugs tied back just above the diff. You want to loop the rear diff lock detection switch which is a 2 wire plug with 1 black (earth) wire and 1 blue with yellow trace wire (power). Loop them and it will act as if your diff lock is engaged. You may need to just turn car off and back on to clear the dash lights once you unplug the wire to re-enable everything ....I was turning car off to plug and unplug wire before I fit the switch anyway. No codes show with scan gauge. No fuses blow or damage done as the power going to earth activates the dash lights which stops a short circuit. I have had no faults/ codes/ blown fuses/ bad smells or anything and I have had this done for a while now. All I am left with is a triton that I can now turn tc off when it suits me which I believe should of been standard.

[chrisdoherty87]

Unplugging speed sensor on one wheel also disengages but I have not played around with that to see of any other things affected.

[Cowboy Dave]

Well now this is starting to sound pretty interesting. Does the rear locker light come on at all?

[chrisdoherty87]

No. Not sure I've seen a rear locker light? Lights on dash are just abs, stability control and traction control. Definitely works though as when turned off it will spin wheels/wheel for as long as you like with no cut outs or wheel braking. I did it for sand as I find the tc far too intrusive when on beach mainly in 2wd. I did try it in ripley (bush 4x4 tracks QLD) on some big hill climbs and as suspected I couldn't get even half way up after many tries without tc and turned it back on and crawled up. It is a good system on most terrain as we all know but the option to turn it off now is a nice touch.

[chrisdoherty87]

Haven't actually tried to lock the wheels up under brakes to confirm abs is not working but I'd say it too will be out as it appears they run off the same system.

[Cowboy Dave]

It makes sense so far. I'd be keen to give it a try if I was doing sand stuff. But what it has reminded me is that I wanted to get the RDL light to work when I activate the ARB rear locker. When I started to look at it I thought I was going to have to go in behind the instrument cluster and I wasn't too excited by that prospect so gave up on it. It hadn't really occurred to me (but should have) that the other end of the loom might be easier to get to.

[bill65]

Hi Chris by putting the switch into the dash. Did you run the wire from the diff too the cab or did you pick it from the difflock wireing in the dash? Thanks bill

Not sure if I'm understanding this?

AFAIK, on the earlier MN's like yours, there is a TC button to turn it off?

What I thought you would be looking for is traction control to be on when you engage a rear locker...although you have a front locker so that is probably incorrect..

[Cowboy Dave]

No the button turns off ASC but not TC. I'm not worried about turning TC off but would be if I was doing beach driving as others are discussing.

I just wanted the ARB switch to talk to the dash so that the OEM DL light would show up as on when the ARB locker was on. Not essential, but aesthetically it would be a nice touch.

[Homer]

self moderated about the gheyness of that post

[chrisdoherty87]

Dave, yeah definitely no diff lock light. There is a control module that is normally fitted with the factory option. Id say that may control the diff lock light. I do not have that module I don't think.

Bill, I have every intention to trace the wires back to ecu somewhere and bridge it with a switch there but for now I have just run wires from the back.

[ag9111]

Already know about the diff lock but that will throw a MUT3 code C1293. ABS, ASTC off and ASTC lights will be on. Your scan gauge cant read or clear codes starting with CXXXX
Playing with wheel sensors will give a code between C1200 and C1217.

Any other ideas?

So are you saying this mod Chris has done will cause a code?

Chris do you have asc light staying on?

[chrisdoherty87]

Lights stay on dash the whole time the switch or wire is in which gets rid of tc, asc and abs. Unplug the wire or turn the switch back and the lights go out and car is back to normal. I can't varify if it has mut code but definitely no code on scan gauge.

Yep but not one you can see

[chrisdoherty87]

Do these clear over time or do the dealer have to clear them? Cause any issues?

[swampview]

Just to clarify a few points,I too have tried this and it works beautifully.I went a step further and hunted around for blue wire/yellow trace behind the dash to no avail (I was hoping that it was attached to the diff lock switch plug,which resides next to the asc switch behind the dash even if you didnt option a diff lock).So instead I settled for tracing it back to the passenger side lower door trim panel,which is easily popped off).One bundle of wires comes from under the seat and heads rearward,the other bundle of wires comes from the same place but heads forward,it is in this bundle that the wires will be found.

There are two blue wires with yellow trace in this bundle so you have to choose the correct one (which is of a smaller diameter than the other) .Earthing this wire will disable all of the electronic braking,without any dramas,as it is the sensor wire that makes sure that when the diff lock is engaged no electronic braking is applied.By earthing it you are tricking the computer into believing that the imaginary diff lock is engaged.

It is very easy to run this wire up around the passenger footwell and behind the dash from this point and with the use of a relay powered from the 4wd light could be only engaged whilst in low range 4wd for example.I havnt got this far yet but intend to do this as a safety feature,so that if the toggle switch is left on by mistake,the abs and stability are switched back on when high range is engaged.

Hope this helps someone, who like me gets pissed of with traction control in soft sand. J

Hi All,

I am wondering how to fully disable Traction Controle and ASC off at same time, at current moment can only disable ASC and traction control stays on cause can feel power loss when driving in sand 4H, 2wd and not just sand..

I have seen on Pajero fourm that they have a plug and play kit that has another button with the kit to disable it completed just wondering if anyone has made one for the triton or know how to.

Disconnect a wheel sensor or bridge out diff lock plug above rear diff.
Why you would what an "open" diff with no traction aids off road I don't ever understand.

[Shodown]

Holy thread revival batman !!

So a few questions.....

So swampview's mod is the same as Chris's.....? And both throw codes.... but not visible to Scangauge?

Are they visible to other code scanners or you need an expensive ABS type one?
