Hi,

Are you using a MUT3 to program the SRS unit and it is not responding, or are you trying to find some way around the MUT3 execution and calibration etc?

Customer: replied 9 months ago.
I USE A AUTEL MAXISYS
Customer: replied 9 months ago.
BUT EVEN I CALL A GUY THAT ONLY DO PROGRAMMING HE IS MOBILE AND ALL DEALER USE HIM AND HE WAS STUCK LIKE ME
Expert:  Doug replied 9 months ago.

Is he using a MUT3? There is no way around this step.

Customer: replied 9 months ago.
OH THATS THE SMALL BOX WITH A FEW BUTTONS, YES AND HIS COMPUTER.
Customer: replied 9 months ago.

Customer: replied 9 months ago.
THE CAR DONT HAVE ANY OTHER CODE
Customer: replied 9 months ago.
HE TRIED TO PUT THE OLD ONE TO COPY FROM THERE BUT ASK FOR A OPT (4 NUMBERS OR LETTERS) NOBODY CAN HELP WITH WHAT IS THE OPT
Expert:  Doug replied 9 months ago.

What revision is his MUT3 at?

Why couldn't the dealer do it? Is this a used ecu?

Could they communicate with the SRS ecu? Could they communicate with the OCM ecu?

If they can communicate, what does the VIN read for each ecu?

Customer: replied 9 months ago.
HE GO TO THE DEALER AND ASK ALL THIS QUESTIONS AND THEY SAID THEY DONT DOIT BEFORE THEY NEED THE CAR THERE TO CALL THE HELP LINE TO THEY GUIDE THEM BUT THE DEALER IS 40 MIN AGAIN FROM ME THATS WHY IM TRYING SOMETHING ELSE
Customer: replied 9 months ago.
THE SRS IS NEW FROM THE DEALER
Expert:  Doug replied 9 months ago.

Well yeah if you are just carrying the thing in they can't do anything with it. The car must be there for it to be coded.

I'm not sure there is an actual problem here, apart from just not following procedure.
The car must be present to code the ecu.

The ecu can not be coded with any tool other than a factory MUT3. No exceptions.

Customer: replied 9 months ago.
WHEN YOU READ THE SRS ONLY HAVE THE VIN ALL THE INFORMATION FOR THE SEAT BELST , SENSOR ALL THAT IS EMPTY I DONT KNOW IF THIS ANSWER YOUR QUESTIONS
Customer: replied 9 months ago.
HE HAVE THAT
Expert:  Doug replied 9 months ago.

So he was able to write the VIN with the third party tool but can not code it... and that makes sense, because you have to have a connection to Mitsubishi corporate web site via Dealerlink to download the coding file, which the MUT3 then writes to the ecu.

Customer: replied 9 months ago.
Expert:  Doug replied 9 months ago.

So, you are still back exactly where we started.... you need to have the vehicle coded via a dealership with MUT3 coding receiving a coding file via Dealerlink.

I know this is inconvenient with your 40 miles to a dealership, but unfortunately there is no way around this step as I mentioned initially. It has to be done with a MUT3, and it has to be done with the vehicle present so that the dealer can write the file to the car.

Customer: replied 9 months ago.
THEN SAID YOU CAN'T CONTINUE BECAUSE YOU HAVE A DTC, SAID FIX THE DTC BUT THE ONLY CODE THAT GIVE IF YOU SCAN THE CAR IS THE THREE THAT I SEND YOU, IF A POSSIBILITY THAT THE CONTROL MODULE CAME BROKE OR WITH DEFECT SOMETHING FROM THE DEALER
Customer: replied 9 months ago.
OK THATS MEAN I NEED TAKE THE CAR TO THE DEALER
Expert:  Doug replied 9 months ago.

I would find it highly unlikely that the ecu was damaged or used from the dealer.

If it were damaged you would expect either no operation or trouble codes other than the ones you have. The three you have are just typical faults for a not-yet-coded ecu.

If it were used it would be easy enough to tell (at least on a MUT3), when you check the ecu information on this model it will not only show you the VIN, but on the MUT3 it will also show you the "first" VIN, so even if someone returned it the first VIN that was written would still be present, listed separately (some other scan tools can read this, but not all).

Customer: replied 9 months ago.
OK
Expert:  Doug replied 9 months ago.

I know its a bummer not being able to do stuff like this outside the dealership, but unfortunately everything that requires coding files at this point is dealer only. In the future you'll find aftermarket scan tools developing "Save" functions for the coding to extract for writing to a new ecu as that has been developed in the past (early 2000's vehicles), however even at that it is only good from a known-good ecu (if you have for an example an srs ecu that is damaged or deployed bags, it won't help you).

The only alternative to a dealership would be cost prohibitive (buying a MUT3 and knowing someone at Mitsubishi with intranet access to get you a coding file... unrealistic expectations unfortunately).
