Hi there all, wondering if anyone can help me. brought a ralliart engine with lsd gear box. change the ecu, bcm, wiring looming and wouldnt work. took it down to mistu and got my key from my vrx code to ecu, did work cause of the BCM. Brought a new BCM, installed it then their couldnt program the key to the new BCM.

I check the dissie, leads and spark plugs and their are sparking . check the fuel in the rail and the fuel pump is working.

Cant get the key for the ralliart as moore parts plus lost it.

What should i do???

If anyone can help, please PM ASAP

many thanks
Nathan

stay on line some one might have the answer

go back to the step where the bcm was working need to recheck the new bcm wiring and instructions undo the battery terminals for a few minutes to clear any faults in the ecu

see what happens
did that, still did the same thing

hmmm im not an expert or anything but i'll have a crack. does the car try to turn over at all? maybe check the starter motor or maybe it could be something electrical, something along the lines of maybe your immobiliser.

i would try to put in your original ECU and BCM and see if it runs.

Changed the start motor that works, changed the whole dissie, car starts but wont turn over. driving me :nuts:

Different wiring loom between the the ralliart ecu which is manual ecu to the vrx ecu that is semi-auto ecu

what do you mean by starts but wont turn over?

New BCM should haave coded itself to your ralliart ECU - either that or it's been used before by someone else.

Give me 5 and Ill see if I can find anything in the service manual.

was the vrx an auto? If you have put the Ralliart loom in and a manual it wont crank because the transmission ECU thinks its an auto, wont recognise that its in neutral or park.

have you check the battery just in case you killed it? this can happen as it happened to me not to long ago.

have you still got the same gearbox in your car? or have you converted it to manual?

the start motor turns and the the spark plugs firer but thats it

Hi there, the ne BCM coded to the ralliart ecu, but then my key would code to the ecu of BCM. it was brand new in the bag cost me $180 for it.

Cheers mate anythink

Hi there, i have changed everything, the vrx was semi, but i have the ralliart motor ,manual box, ( ralliart manual ECU), key reader ring, BCM and wiring loom that goes from the ECU though the firewall into the fuse box in the engine bay

have you checked your air filter see if its cloged or not, any air flowing into the engine?

checked and its was cleared

Have you been able to get any sort of diagnostic code for the car either from MMAL or yourself?

The guys at MMAL should have "teached" the BCM and keyed your key ID on the MUTII

tryed that, the MUTII couldnt fine my key:confused:

Sounds like the new BCM might be a dud.

Ill link some images of the manual in a sec - I don't know if their going to be much help.

Starts with the basics then goes into some of the diagnostic codes:

http://i59.photobucket.com/albums/g291/dave_au2/bcm2.jpg Diag code 11
http://i59.photobucket.com/albums/g291/dave_au2/bcm3.jpg Diag code 12
http://i59.photobucket.com/albums/g291/dave_au2/bcm4.jpg What the MMAL guys should have done
http://i59.photobucket.com/albums/g291/dave_au2/bcm5.jpg Basic troubleshoot - key wont start
http://i59.photobucket.com/albums/g291/dave_au2/bcm6.jpg Diagram of BEM pins - pin no. 4 is the datastream to the engine ecu, 10 is ignition feed (14v active, 0v inactive), 21 is diagnostics, 44 is key in ignition (active O/c key in, inactive 0v key out).

- did the MMAL guys say anything at all about any diagnostic codes that the car gave when the key couldnt be identified?

Oh and before I forget, for new teamsters at home, you can get diagnostics out of your car without having a MUTII.

Although Im not sure which warning light it would be in this case - maybe engine?

Daves right. If it doesnt recognize your key, it wont run.
I would be going back to Mits and getting them to hook up the mut and get it to recognize your key. I think you may need new keys though. Good luck and let us know how you go.

How'd you go?
Found that it has nothink to do with the key, ECM.

Whats now happening that the fuel injecters are not turning on and not letting the fuel to get in to the motor. fuel rails are full on petrol, but the stupid injecters arent pasting the the fuel throught into the motor.:confused: :confused:

Hey Nath,

Don't quickly rule out the key just yet.

From memory I think the immoboliser works by disabling the fuel injectors (and I thought also the sparkies as well) so it could still be the security system! I'd say check and re-check your wiring from the ignition barrel (and specifically the key reader ring) to the BCM.

It sounds as though the BCM has linked up successfully to the ECU especially since you bought them both from the same car. Or did I hear wrong and you ended up buying another BCM? Either way, just make sure the ECU and BCM are talking nicely to each other first, then focus on the key?

If the BCM can't detect your key then my first reaction is faulty wiring or a faulty key reader, worse case: faulty BCM. Without the key being recognised, your car will be immobolised!

So how did you go? Is it running yet?
