In one word - no it doesn't work. Actually thats a few, hey. But still ruddy cheap for a remote and transponder, it does have the membrane in it too. So you would simply need the services and key cutting (not supply) abilitiy of the good old auto locksmith as we started with. Cheers guys!

Believe it or not the panic button on my remote with the replacement case from China does work!!!! I must have used the membrane from the new one as a happy strange thing, only discovered it when my girls got the keys and set it off!!!! I'll dig out our spare remote for the battery and have a go for a laugh in the mext day or so.

Bugger, never thought of the power thing.

Well the key / fob / membrane / remote has arrived from China!! But the programming instructions didn't come with it, and the link from QinteQ doesn't show 2004 - 2007, unless the other method for up to 2003 works? Any ideas gents?

Yep, easy! Yet again ebay comes up with it. Search for usb to av cable, then also female to female usb adapter. Less than a fiver should sort it. However I have yet to try it, but think I should have a go!!

Ah, possibly a large technicality, they are for the 3.3 - petrol. However there is definitely some confusion on it, on the American mini van sites they reckon that they will just swap - but as I say it didn't sort mine!!! Also seen a few on there with solenoid changes that didn't sort it, but then some did. And if it's a no charge event then it would seem completely genuine too, fingers crossed for you - let us know! The PCM ecu would have to be reset to tell it to accept your transponder on the keys, but that's not what we're talking about.

The TCM's I have are P04686707AI that a capital i at the end S/N TEFTH293725JZ7 P04686760AD s/n TEVTH0069196BL by any chance do either of these match? They didn't on mine, but after disconnecting the battery to fit them sod all different happened but no fault code. and the bad timing news is we go away for a few days till Friday in the morning

Hi guys, I've had enough of trying to fix it, it drives fine in 2nd gear or reverse. Is anyone interested in it, only 2 owners with a proper service history? It's now sorned as the insurance ran out and I am naffed off. 2 professional mechanics I know couldn't sort it, tried replacement TCM and PCM's. LPG with certificate and "alternative fuel" on logbook, 91,000 miles, 2 owners including me (for 4 years) Silver, cloth seats, manual sliding doors and tailgate. Apart from the ruddy gears, and no speedo, everything works. We are in Stockport, South Manchester. Send me a message!!

Smashing! Good result hey! Flipping electronics on these things really do have a mind of their own.

Come on Lewis fill us in!! What was it?

I've got bigger problems with my 2002 3.3. Only get limp mode. But ended up as they were not very expensive with 2 spare TCM's. If you would like to borrow one to try you are welcome, if you cover the postage cost, if it works send me some more money, if not send it back! But doesn't sound like an ecu as you say temperature affects it.

ooh not sure on that - I may have read somewhere (could be wrong) that once a key is registered it can't be used on another, no idea how that happens. Oh hang on, just read "key" as you put, so the blade won't work in your locks of course, so it's no use. However - an AUTO locksmith - a good one - should be able to provide and cut the key / transponder anyhow. And help with the non working fobs too I should hope. It's not batteries is it? Only asking! I paid £60 for a new key, which wasn't particularly cheap, and they struggled to cut the key, at our "shop front" guys, supplied and coded in.

Just search "Chrysler 5 button remote fob", just found a few. If you mean the panic button is the 6th one then yes - mine did!! There is one from China at £9.83, inc postage!!! http://www.ebay.co.uk/itm/Key-Fob-Head-Ignition-Keyless-Entry-Remote-6-Buttons-for-M3N5WY72XX-Chrysler-/231697139929?hash=item35f239c8d9:g:f4sAAOSw0HVWAT5L Very long delivery time though!! But it has the key transponder in it too, and a blade that just need cutting. I am that intrigued / impressed I just ordered one. As I have 2 keys it says I should be able to program it in - I will post it on here yay or nay when it arrives and I give it a try.

Yep, thats right, and don't be put off by "oh no it can't be done". A decent auto locksmith can and did do it. Once they had the pin number took about 10 minutes tops. And my 2nd hand one works just fine on all functions. My local shop-front auto locksmiths couldn't, they said it was a dealer only part and job. In the same way that a tyre with a screw in the edge of the tread "can't be repaired" YES IT CAN. What they mean is we can't do it, because we don't have the ability to do a heat vulcanise repair. But most won't tell you the full detail and truth.

A good auto locksmith (not electricain) can program in a 2nd hand remote, I had one done, got it off ebay, and they should be able to cut a key with transponder and code it to the car as well. They would need the pin number for the car to code in the remote, it's not the radio code. There is a very good mobile guy near Manchester, but you don't say where you are

Only 1 left - hope it doesn't sell!

I got top and bottom hoses off Ebay for my 3.3 a couple of years ago, great service. They are Car Parts USA, one on right now at £29.99 +£4.10 postage.

I'm gonna need the luck I think. Got nothing to lose so while it's dry and light at night will strap up another earth somehow. I'll keep you all posted!!

Well, on further investigation it does look like 96 to 04 would appear to be interchangeable....... As long as you go for the same engine and gearbox mating. We'll see.......

Just a thought, if I have ended up with a replacement TCM that's duff, any idea if one with similar but not the same part number work? Yes I appreciate it may have different shift patterns, and other things, but if it's the same software from an earlier version, and above all if it communicates, then it's a step forward. From the very detailed info on the data sheets it seems they lose any learned stuff on a battery disconnect anyhow, and go back to standard parameters. I cannot find another with the exact same number now. I've been outside under and over the damn car most of the afternoon and can't see anything untoward, the unit is getting 12v, the ignition switch 12v happens correctly, the pci wire bells out ok. I also found the "red wire splice" that various forums refer to, it's in the big wiring loom tube directly in front of the transmission, bugger all wrong with mine. I can't find any earth straps that they refer to, other than on the starter motor. In my mind it would seem the 2nd TCM appears to be a duffer, but have no means to check this of course, can't find anywhere for info with resistances through it.

Cheers, VERY useful link. Sadly it means my 2005 car can't swap the TCM to check it, they have changed it to a combined unit instead of separate engine ECU and TCM,arse. Back to the 2002, I have done a continuity test on what is supposed to be the bus wire from the TCM pin 43 to PCM behind the battery and that wire is fine, sadly. And opened up the wire harness underneath, and again sadly all look and feel ok. But the problem is a lack of communication TCM to PCM and that sodding wire is fine!!!!!!!!!!!!!!!!!!!!!!!!!!!! And yes it's got a good earth back to the PCM, I did check that.

Ok then, I thought I was going to be clever and put the old TCM on my 2005 car, anyone know where it is??????? Cos it's not under the wing like the 2002!!!!!!! I can confirm thought it is getting 12 volts to pins 56 + and 57 -. Or anyone know of any tests with a multimeter I can do on the TCM????

Yes, it drives beautifully smoothly, but only selects 2nd of the forward gears, won't change up, and still selects reverse, park and neutral, silently - no graunching. I get the same results with the TCM disconnected. I have seen the posts before on the earthing problems, but they seem to have different symptoms, jumping gear and into neutral while driving. I don't know the make of the scanner, it belongs to (thankfully) a good mate who owns a workshop. But as I said it sees all the seperate items on my 2005 car, inc the TCM data, and the on the 2002 one with the problem but not the TCM. I am popping down there tomorrow, will let you all know if I weigh it in for scrap or it's further investigations!!! And thanks for the input, I'm getting naffed off with it. I am heading to thinking I've been really unlucky and got a duff 2nd hand unit too!

Hi guys, On our 2002 3.3 V6 I've been struggling to find the cause of the code, "no CCD / J1850 message from TCM / PCM" It drives fine - apart from the fact it's in 2nd gear, or reverse - with no speedo All the gear indicator blocks are illuminated. I have access to a proper full on code reader that will see the TCM unit on our other 2005 car including solenoid pressures etc etc etc, I have physically checked the wiring, checked all fuses, relays, swapped some around to check just in case. I've swapped the TCM, and the dash / clocks console. But no change - and the code reader doesn't "see" either of the TCM's. Any clever ideas fellas???? If I can't sort it I will sell it, we've had it 4 years, up to now been great, only 1 previous owner too, and a genuine full service history. LX model but with full leather and multi CD changer, and on LPG.

Jolly Damn Fine Result!!!!
