Thread: D4 CV Joint Failure ????

Thanks Graeme. I'll see what can be achieved with the IID tool today.

I tried putting it into low range on Friday, at the same time as selecting Rock Crawl mode to deliberately "lock" the centre diff and then switch everything back to normal driving / high range. It went into low range and back to high range without any problem. It also went into "Rock Crawl" mode and indicated centre diff locked on the touch screen display, and then indicated centre diff unlocked when I switched back to "normal" driving mode.

Brian.have you tried reversing it for a reasonable distance whilst steering right and left.The transmission may be "wound up" and unable to unlock the CDL.

The CDL has clutch plates rather than gears that slide so can release immediately providing the clutch/range motor is operating and is correctly calibrated.

OK - so I've now got the Gap IID Tool all set up and activated (took me a while as I am no genius when it comes to computers / electronics and am very wary of hitting a wrong button and permanently stuffing something up).

From what I can see on there, it would appear that the problem is definitely with the transfer case / CDL / clutch plates. I went in to the error log section and, apart from a couple of obvious ones like "the door is open" and "the ignition is on" - the only error listed was .................

TCCM - Transfer Case
HSCAN - 1 fault

P2789-00 Clutch adaptive learning at its limit.

Triggered on 03.02.2017 18:15:58 at 128,114km.

Going by that, the "alarm" was not triggered when I drove through some water, which occurred a couple of days before that. Looks like it was triggered when I raised & lowered the suspension / tried changing to low range & back to high range / tried engaging the CDL by selecting "Rock Crawl" mode and then returning all to "normal" settings and reversing vehicle into the shed on Friday evening.

So, while there was definitely a problem for a couple of days before that, it doesn't look like any "alarms" had been registered until I started playing with the vehicle settings on Friday.

And just to really top off my day .................. I had to go out and empty the trailer at the tip today and then pick up some building materials from Bunnings for a job I'm doing inside the house .............. driving a bloody Camry.

What you need to do is go into the "Calibration" option on the main menu of the IID Tool once connected.
Then select "TCCM - Transfer Case"



Then do "Calibrate Clutch" option
You shouldn't need to do "Calibrate Position Sensor"

also check connectors to the TC for corrosion , it can take a while after water ingress to show up.

Thanks for that. I've now got it up on a decent set of axle stands and will be able to get in underneath it tomorrow and go right over everything that I can see, including electrical connections etc.

Following that, will attempt calibration with the IID Tool - although I've got to admit that part of the process makes me nervous.

At the moment, I'm sitting here going through the seven and a half thousand odd pages of the manual I bought from Dave's shop, looking for any reference to that error code and other relevant information. While it is a very detailed manual, it is a real bugger to find anything in. So I have got a spreadsheet open alongside it on the same screen, and while I'm going through the manual, I'm developing a more user friendly "index". Once I've got that working as I'm hoping for, happy to send anyone who is interested a copy.

Justin.
Is there any calibration available for the transmission itself with the idtool???
