Boxer 2.2 - Denso Injectors Coding

[dfidalgo]

Hi,

I have a 2008 Peugeot Boxer, Puma 2.2hdi engine, Denso injection.
The engine was replaced (complete, including injectors) however the "new" injectors were not recoded into the van's ECU programming.

The original codes that are programmed are 16 characters long, however current injectors only have an 8 character code that the diagnostic program (diagbox) does not accept.
The injectors in question are the 6C1Q-9K546-AC, and I cant find any code on top connector, just the following codes on side body of injectors:

1 - 6C1Q-9K546-AC 09J 80063

2 - 6C1Q-9K546-AC 12H 36797

3 - 6C1Q-9K546-AC 10J 39849

4 - 6C1Q-9K546-AC 09K 41705

I would like to know how I can convert the 8-digit code of the current injectors to the 16 characters requested in the diagnostic software.

Thanks in advance,
Daniel

Aren't the codes just the last 8 alphanumeric of the above?

It makes sense that it would be those last 8 digits, but Diagbox doesn't accept them. Diagbox only allows you to enter a 16-digit code.
Could it be that my ECU software is not compatible with these injectors?

Let me have the VIN so I can see what it says about these. Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff.

Ok, so being a Ford, this looks like a Visteon Injection ECU.

Information suggests the following:

If it is not accepting the code then have you selected the incorrect information in Diagbox? Did Diagbox autodetect everything from the VIN or did you enter details manually.

If you have selected the incorrect injection system or other information then this may be why it is not accepting the codes.

[dfidalgo]

You are right regarding the lack of autodetect of the VIN/van details, when I enter the diagbox I am forced to manually enter the VIN and model of the van (I always choose the Boxer 3 option, am I choosing correctly?).
But after that, the Diagbox correctly identifies both the injection ECU (Puma engine, dcu-102 ECU) and the BSI.
The diagram you posted from Diagbox showing how to enter the injector code is the same to how it appears to me.
Is it only supposed to accept 8 digits?
(When I try to enter just 8 digits, Diagbox responds with an error saying that there are invalid characters in the code. I tried all 4 codes, always the same result).

1) What other options did you choose when selecting vehicle type
2) Did it ask for the build date? (RPO / DAM) and if so what did you enter?
3) Did it ask to choose the injection system and if so what were the options and what did you choose?
4) What version of Diagbox are you using?

Anything else that might be relevant.

1 - Just the Model (Boxer 3) and manually the VIN number.

2 - No, never asked

3 - No option for that too. After connected, Diagbox lists the present modules. In this list we can see the BSI (NBC) and the ECU Injection/Ignition (Puma).
If I enter in one of these control units, I can see all parameters, live data, options from Repair menus, etc.
I can't do telecoding because I'm offline...

4 - Diagbox Version 7.62

The Injection ECU was opened before by someone, and reprogrammed (immo related I think). For some reason, the injection ECU don't fire any faults, never. I don't know if it is possible to someone deactivate the faults trigger on ecu code, but this is odd and very bad to diagnose the van problems.
In another hand, BSI triggers and stores faults when they're present.


Anyway, are you sure that it is supposed to Diagbox accept a 8 digit injector code?

I suspect that I'll need a 16 digit code (I think that Denso injectors have at least a minimum of 16 characters, what correspond with the diagbox diagram/representation that you shared above. Maybe, somehow, the top connector codes are missing in my injectors?).

[GiveMeABreak]

With that extra info:

If the injection ECU has been tampered with - this may well affect its operation.
With the VIN I can now see that it is supposed to be 16 alphanumeric for the injector codes, I didn't know which system you had before.
Your Van's build date is November 2006 so is Euro 4 standard, so that rules out Boxer 3 Euro 5.

So there's nothing much more I can add - whether whatever has been done to the injection ECU is affecting the ability to accept the codes I can't say, but it should be 16.

[dfidalgo]

Interestingly, the van was registered in 07/2008. But I always excluded the "Boxer 3 Euro 5" option because Diagbox says that when the sixth digit of the VIN is a "B", then the van is a standard x250.

Now, being the conclusion that the code should really be 16 digits long, why do the Denso injectors that are there only have 8 digits?
Is there a possibility to someone convert the 8-digit code into 16 digits?

And one last question, or request for advice, do you think it's worth taking the van to a Peugeot dealer to have the injectors programmed, or even have the ECU and BSI updated?

Thank you very much!

Your Build code is 10960, which equates to 11th November 2006. (I originally had January in my last post - but have corrected it now). It's a BOXER 3 VAN LONG WHEELBASE H2 TYPE 14 2.2 HDI 120 PUMA Manual gearbox 6. Not sure what the 'X250' is you're referring to, but the 6th digit, is a 'B' which refers to the engine which in this case is the Puma 2.2 120.

Never use registration dates as vehicles can be stockpiled before being sold (for years in some cases) which results in a late registered vehicle, when it's a lot earlier in reality. So the date I have provided is from your VIN and is the date your vehicle was built at the factory - which makes a difference to the parts and systems fitted of course.

There is nothing I'm aware of regarding conversion - the codes are unique to each injector at factory / reconditioning to ensure engine ECU uses correct timing and fuelling based on the individual injector tolerances.

As for getting the dealer to look at it - that is a possibility, but I suspect if the engine ECU has been interfered with they will have the same problem. If they detect an issue and recommend downloading the engine ECU software, then this may override whatever was done regarding the immobiliser. I can't of course answer why that was done in the first place - but does factor in other problems like why was it done and is the engine ECU correct for this vehicle? Which of course could explain why the codes are not being accepted if another ECU of the incorrect type has been fitted and has been reprogrammed to disable the immobiliser protection and who knows what else. If that was the case, then this is the time these sorts of things will present issues when anything in the engine ECU needs to be changed like injectors coding.

If the replacement engine came fitted with injectors then this means the old engine still has the original injectors. Can you look at them to see what is printed on them? Could you fit these original injectors as this would solve the recoding problem?

[GiveMeABreak]

Not if the engine ECU is different I suspect. Unless I've misread, only the replacement engine with it's injectors was replaced not the engine ECU - so if the engine ECU has been modified in any way because the replacement engine was different, it may be the reason why it is expecting a different type of injector (for the original engine). In other words was this replacement engine an identical engine with the same engine code, or a different variant - 'similar' engine?

[Paul-R]

Yes, I read it as the original engine ECU was still being used. Although there appears to have be some 'tinkering' with it. If that was before the engine was changed, and hence the the old engine was at least running with that ECU, then there may some scope for using the old injectors. If the tinkering was after the engine change when trying to get it to run then that makes it more difficult and, frankly, unlikely to run properly.

In any case, if the old injectors are available then it would be interesting to know what is printed on them.
