Hello welcome to JustAnswer, My name is XXXXX XXXXX I will be assisting you.I see your question has been up for several hours,Do you still need any assistance?Thanks,
thanks Brad, I think I will ask more specific stuff once I get more into it.
Attached is the dignostic report I had done by a auto transmission specialist.
Temp Light coming on I get "Transmission over temp" and "serviceXXXXX
The service manual tells be to look at 21-443,:sensor transmission temp which is part of the TRS which appears quite complex, whats your thoughts?
The reason why I am leaning towards diffs as they have a temp sensor too and last month I changed the diff mounts and dropped the front diff 6-10 inches with the wires still connected of course they were forced to disconnect after that, they looked good but....? warrant some testing now?
Other codes that are fixed B1668 we put led in ..taken out and originals in.
Codes: u1408 c107c these items work fine.
The glow plugs, Australia is a hot country our temp hardly ever gets below 40f. Do we need them can I disarm that circuit?
I think I only have the codes U0415 and overtemp + service transmission left, what do you reccommend I look at next with the service manual ref numbers?
Vin no: 6Y165276.
Also I have brought two scanners
I returned this one and replaced with:
Neither scanners can read any codes except for:
U0101 Lost communication with TCM.
The supplier of the ms609 is suggesting the TCM is bad and has suggested trying to clear the above code and disconnecting the battery to see if that takes the car out of limb mode.
Below is scan reports from a Auto Electrician that I had done when I replaced the battery last week.
Hi Brad, I am stuggling with just a wiring digram without more info where to test, I did find in the junction box fuse F3 10 amp has no power to it.
With my scanner I only get one code "lost communication with TCM" I have the 2005 /08 WK service manuals and wanted to carry out tests 8E-236, but cannot find the TCM to unplug TCM C1 Harness!
The company that supplied the ms601 scann tool has came back and said bad TCM or associated wiring.
Trust this is not frustrating you?
from the test above on the transfer box motor, if the TCM detects this faulty will the TCM shut down all communication and put the jeep into permenant limp mode untill those codes C140A are cleared which in turn making the U0101 error false.
Solution / logic?
Under these fault conditions my scanner wont get to the TCM to clear the C140A code because the TCM has shut down communication.
Whats the opinion on, as I have fixed some codes with brake lights etc, just concentrate on the transfer case motor which is sugesting a short which I should be able to pull apart and confirm fix as nessary then back to the mechanic that can clear these codes or the dealer just for a starscan and report and clearing of codes.
For a complete wiring diagram, refer to the Wiring Information
With the ignition on and no undervoltage or overvoltage condition present.
A faulted condition is detected in the H-bridge driver.
I have installed the remanufactured from the USA transfer case motor, I have not touched any wiring just plugged it in.
I also have my own scanner now that works from the USA as well Autoenginuity enhanced Chrysler package.
I have these codes:
FCM and ABS U0101
Enhanced power train, U0101,P0676, P0672, P0671
When I try clear codes the vechile refuses to clear them.
Other warnings on the dash
'serviceXXXXX "Transmission over Temp" ETC flashing when engine is on / off. ESP/BAS light on all the time.
The car is in Limp mode.
I have found the TCM, behind the radio I think Jeep changes things for the RHD cars and its not altered in the service manuals.
What do you suggest?
No diagnostic codes retrieved
I have confirmed there is 12v and a ground on the TCM.
Your recomendation next?
The voltage to pins 6 and 14 is 2.4 to 2.45 volts. Resistance to earth is one indicating no short to earth. Battery voltage 11.5 but its a new battery and I suspect is a little flat because of the testing leaving the key.
The procedure I followed, scan enhanced powertrain and show all codes.
Delete all codes.
Scan all enhanced power traincodes, save scan results attached above.
Also confirmed DLC pins 6 and 14 still 2.4 volts and no circuit to earth all still good.
Confirmed voltmeter reading accurate against my travel trailer solar charger....voltmeter confirmed good.
Should I put a 20 watt test lamp across pins 6 and 14 to confirm voltage under some load?
The glow plugs are plugged in untouched, a supplier in Europe has suggested I take one out and send him the part number, $12.00 ea there $80ea in Australia! I dont think they are the problem but it will remove three codes!
Found the TCM attached is a photo, last night I tried two autocomputer remanufactures in the USA with one cant do and one no responce, could be because its a MB Seimens / european part?.
Do you have any suggested suppliers? I imagine the dealer here will be arount $2000.00.
The TCM cannot be repaired or even tested in Australia.
The Jeep dealer has no stock in Australia they have to import, they came up with the same part number as you. But in the photo above it has a different part number. Guess we use the part number you and the jeep dealer specified?
A TCM supplier in the USA is offering a rebuilt one with life time warranty plug and play programmed with my vin and milage for $500.00 includes a $150.00 core charge.
If I buy new it will not be plug and play?
I will need to go to the jeep dealer and get them to programme, should I ask them to give a estimate to programme it in the car and maybe a starscan after? They wanted $900.00 to import a TCM for me.
Whats your advise new or rebuilt considering the above?
I am replacing all the glow plugs, What a tricky job! You guys must be a mixture of Dentists / Surgeons extracting those!
Got the TCM today part number RL692392-AI they said superceded our part numbers.
Pluged it in scan...deleted all codes....scan again...have not started motor.
Glow plug issue gone.
1/ occupant restraint controller: B210D low voltage , note battery voltage 12.4
2/ TCM: P1644 incorrect config.
I have not started the motor as yet.
Your next suggested procedure?
7th Aug 2012
Hi Brad latest report attached / below
Plugged in the new TCM part number RL692392AI.
Ran a scan and then cleared all codes.
Ran the scan again and got two errors. Glow plug issue gone. Other dash board warnings have gone as well. I have not started the motor as yet, in a couple hours I will.
Started it no fault codes on dash, engine cooling fans returned to normal. Park to rev OK, rev to drive ok, stays in 2nd or 3rd gear after driving 300 yards up to 50mph. Turn around come home same. no dashboard warnings on.
Run scan below are results New codes MIL and P0700 previous still on B210D P1644, A hour later I cleared the codes took it for a very small drive and the same codes came back.
Update: Brad, I took it to the dealer in programme the TCM and other computers in the car.....All fixed Runs Great!
All fixed now, the Dealer programmed the new TCM at a small cost.
It runs great.
