TC & HDC not working, D2

[Redback]

OK, my traction control and hill decent are not working, even the lights on the dash are not working, which seem odd, last time I heard the dreaded bong bong bong of the 3 amigoes, only the ABS light came on:eek:

Now here's the odd thing, you can hear the modulator working, but the light on the dash doesn't come on, also when you lift a wheel off the ground to see if the TC is working the wheel will keep spinning even though you can clearly hear the modulator.

Does anyone know what controls the TC and HDC:confused::confused:

Now with all this, the ABS works perfectly AND no faults logged at all:eek:

Any ideas:confused:

Just throwing a quick thought out there.....since HDC only works in low range and your ABS is working and the modulator is at least making the proper noises, no 3 amigoes and clear fault codes, maybe its a simple thing like a crook connection at the low range switch on the Transfer? No lights on the dash indicates to me that the circuit isnt complete either no fuse, poor switching, SLABS ECU plug or earth.

Baz that happened to me a couple of times a few years ago - I got under the truck and removed the connector for the transfer case hi/lo plug and cleaned out both ends with contact cleaner and then slid it in and out a few times (...please people) and from that point on it was sweet.

Thanks guys, checked the hi/lo switch, it's not in good condition but, it seems on the manual the TC should still work with it disconnected, but will get one, as it needs replacing anyway.

Going to get another SLABS ECU and check the connections and earths when we change it, also a few times when away the speedo stopped working, going to look into what might of caused this, it may be related.

No worries mate. The programme is much more aggressive in low range though. Funny thing is that the HDC should chime and flash nonstop if its is applied in high range. Let us know how you go.

It chimes in hi and low at the moment, no flashing though:mad:

Mate - I will have a look again - you might have a blown bulb, or otherwise it might just work that way, but sounds very much like a dodgy high low switch or connector.

Cheers mate

Doubt it's a bulb... They are LEDs.

think its telling u a d4 needs to be on order

No no no...Baz uses his LR OFF road:D

Cheers

A new vehicle is in the near future, probably a D3 though AND it will be used in almost the same manner as our D2:p

As for a blown bulb, I was lead to believe that they were LED not a bulb, will soon find out this weekend though, going to be pulling the dash off to get at the "road speed sensor" (assuming that's where it is:confused:)this may have something to do with this problem.

all the other lights ''test'' fine and work using the nanocom, its only the HDC and TC that dont light.

cheers phil

Sometimes nanocom and slabs-bcu settings play aggly games,how i know?:mad:
When i put coils rear(and vice versa now-air is better IMO),i deactivated sls(only) with nanocom,when i got off-road i could feel and hear TC doing its thing BUT no lights on dash even for HDC,WTF?
I did the settings with nanocom again and everything ok so give it a try again mate.
Cheers.

Baz - checked mine 02 complianced 01 build - definitely HDC light flashing aswell as bonging away when HDC turned on and its not in low range.

When I tested mine to see if the light flashed, I selected low range and turned it on, just chimed until I turned it off, the light was definately not flashing.

Also the TC and HDC lights don't come on when you turn the ignition on, all the other lights do, even the ABS light.

Well today we found the problem and fixed it:MileStone:

It turns out that they had been turned off:eek: only conclusion we can come to is, when we have been swapping files to upgrade the power of the car, somehow they have been turned off:confused:

Anyway, via the Nanocom and a laptop and Kerry:TakeABow: we turned them back on and we now have TC and HDC back:burnrubber::banana:

You were just trying to rediscover your driving skills, or pretend you are driving a Series or Defender to rekindle some street cred :p
