cdl dash light

[tapout]

2000 D2 v8 manual, When i engage the cdl no light comes on, on the dash moving or not, the cdl is engaged and working ive read all through the good oil and other searches on the forums, how do i make it work?

Thanks,
Jason.

I have the same model with manual and have just done a retrofit of the CDL. Give us some more info - does yours have the spiggot for CDL and have you just activated it...does yours have the CDL switch ont he output housing?

Check your connector plugs on the Transfer Case.

cheers.

Hi Oscott, Yes it has the spiggot and it is connected to a home made leaver that runs to the drivers side body rail so i can turn the cdl on without climbing under the disco, i have used the cdl a few times driving some of the tracks with the gclro club, i dont know about the switch on the output housing.
Strangy i dont know about that switch, what does it look like and where is it located on the housing.

Thanks,
Jason.

Jason - it is on the front of the output housing. White connector block. There should be two - one for low range/high range and one for CDL light. Just crawl around the front of the transfer case output housing with a torch. For now just slip off the connector blocks spray some contact cleaner in them and slip them on and off a couple of times to clean and then back on again.

Cheers

I didnt know there is light for low/high range? I have the cdl light not low/high range. What does the light look like?

No light for High and low. The switch however is to tell the ECU that you are in Low for HDC and fuel map.

No, light is for CDL (1 x switch)

The second switch tells the ECU wether the box is in high/low range ... no dash light.

Kev..

[ozscott]

as per above matey. The second switch - hi/low feeds to the SLABS computer. Unless the computer knows that you have selected low range it will not allow you to use Hill Decent Control and lowers the urgency and aggressiveness of the traction control - but no light on dash. You know if it is working cause HDC will continue to chime when you hit the button even when in low range...normally just dirty contacts in that switch and easy to clean.

Ok guys just an update, ive climbed under and had a look around and found this-
male to female plug unpluged, closest one to the spiget.
blue/yellow & black wire going in a white plug and colours out are pink & white, this is cut and taped up, not sure what this is for?
Connected male to female plug, turned ignition on and the cdl tc and abs light comes on, no mater what id do they stay even what cdl is not activated, from car stop or start, do the other 2 wires have something to do with this.
How can i fix this to make it work like our d2a?

Thanks,
Jason.

[tapout]

forgot to mention that originally when i activated the cdl everything worked perfectly, tc & hdc all worked and lite up on dash when going up and down rocky situations, just no cdl light, and there are a few threads on here about being able to disingage the tc for soft sand driving, is this beter?

Thanks,
Jason.

I dont have a CDL light in my D2, as long as I can engage CDL in mud and sand I am happy. CDL works well in sand and mud. Wheelspin elimination is the answer. I dont know why people are saying TC is bad in sand.

I got around to pulling out my hi low lever today and had a good look around at the wires, the hi low switch looks good, one plug was unpluged when connected the dash lights came on, tc, hdc, and cdl, but wouldnt go off, no mater what i did, car on off not in cdl, drive still didn't go out, i found some wires that i thought had been cut (2 wires with elect tape around the ends), thus giving me my problem with lights.
So i took the tape off and this is what i found.

I dont think this is ment to be but i couldn't find any other wires that these would connect to.
Can anyone tell me what these are for so i can restore my dash lights.

[Redback]

There is a switch that activates the light on the dash, if you engage the CDL and the light on the dash doesn't come on, then it's the switch that is faulty OR you need to adjust the cable going to the CDL on the Transfer case.

Of coarse I'm assuming you have a CDL actuator.

[Urban Panzer]

That resistor is supposed to be there, its in the CDL wiring circuit. I suggest you tape it up again.

Agree with Redback, the CDL switch is fubar'd...........they are all connected in the factory, and because they are unused for years, they quite often just dont work.

Fit a new one and all should be good. The switch is located DIRECTLY rearwards of where the CDL nipple is.

Piccy of it in this article, top right picture.

For no apparent reason the switch on my D2 stopped makind contact.
Replaced it and all was back to normal.
What I did find was that when the light did not shine there seemed to ber a difference in TC.
Was it all in my mind or somthing else?:o

Can I ask what you mean you dont have one ? they all have one, and "if" yours is not working, its VERY risky using the CDL and not knowing if its "in or out"

Hi , so when is it meant to come on , i have never seen mine , but notice the tc light comming on and a noise comming from undermeath the car when on the dirt ?

[Riceburner]

I have a light but it doesnt light up, will get underneath and check connections.

There might be some confusion here Craig. The stock D2 (not the D2a) does NOT have Centre Differential Lock - you have high and low range and traction control which is more aggressive in low range. You can retro fit the centre diff lock in these (search for how - even without the internals you can stick in a D1 output housing with the right gear inside as I did) and then you can have the centre diff locked but only for slippery conditions - all gravel, sand, rocks, mud, grass etc otherwise you get tranny wind up which is not sweet at all.

If yours does not have the CDL fitted the light on the dash and noise is all to do with the traction control system braking wheels when they spin to transfer drive to the wheels that are not spinning (or not spinning as much...) through open differentials. Even with CDL locked in for off roading the open centre diffs on each axle still rely on traction control to assist (as it does very much) in low traction situations.

CDL is much better in sand when taking off from stationary than just traction control alone. CDL is also nice in sand at speed is very soft stuff because the vehicle tracks better. I can say this from a lot of experience in sand towing and not, without and now with CDL.

Possibly, I haven't felt any difference in my TC when the light wasn't working, I have replaced my switch a few times, the're a pain and stop working often:mad:
