Suzuki df70...issues...what do you think?

[bassvoodoo]

This has been a 2 year ordeal. I have over $2k into fixing engine and this report below is where I am at currently. Dealership said it was the ECU...so I found a used ECU and put it in and this is what I get...AGAIN. So I ask you people of higher knowledge what do you think and what should I do?

Is there anyone on here that can give me some guidance?

thanks for your help.

Perhaps some further info that describes the symptoms you are having might help. Plus, some indication of what you have attempted/done to rectify the issue to date would be good so we dont cover ground that has already been tried.

Plus, some little patience please, this is only a small forum and it might take a while for someone with specific knowledge of your motor to see your post and respond?

[RayBersch]

Is this the same info as your old ECU reported? Was this part set back to zero when you installed it - I don't even know if that is possible but your report does show quite a lot of hours and I can't imagine that a newly installed ECU would be able to tell the number of hours on the motor. So, as suggested, more info on the problems and attempts to repair would be appropriate.

[Moonlighter]

The report/record you posted, apparently from the replacement ecm, is the history of the used ecm, not of the engine it is now attached to.

As far as used ecm's are concerned there is no way that I know of that the stored history of codes, hours running, etc can be edited or wiped or reset - for obvious reasons - unscrupulous people might delete/alter them to misrepresent the engine's history.

Therefore, the record from the replacement ecm would be pretty useless regarding diagnosing faults with the engine it is now on. You would have to run the engine and then compare any changes between an earlier report you saved, and the next one to see any changes in code history.

You would be better off using the Suzuki sds system and running the tests it is capable of doing to diagnose whatever the fault/s are that you are trying to rectify.

Which we still dont know what they are.....

report history...

This is a diagnostic report from the new USED ECU. the computer is reading the symptoms correctly since the symptoms are very close to the diagnostic report from the old ECU.

I posted to get clarity on this. I have had this motor looked at by 2 different mechanics and the last one was the suzuki dealership and this has been now a 3 year ordeal that seems to have NO end in sight due to NO ONE being able to tell me what is wrong with my engine. so that is why I am reaching out.

ALL the faults/codes flashing and the buzzer sounding had me take it in ORIGINALLY to get it serviced. In doing so neither the mechanic or the suzuki dealership can find the problem. The last thing the dealership said was that the ECU is bad. So I replaced it and re ran the diagnostic report and that is what you are looking at.

I did a random search based on the diagnostic report "low oil pressure df70 suzuki" and it turned up a few posts on SOF that indicated that the DF70 has an ongoing issue that the CAMSHAFT could be faulty or the oil pump. SO I was reaching out to see if ANYONE might/could elaborate on what it could be.

thanks.

The report from that used ecu has nothing to do with your engine!! The ecu has the memory, not the engine or the sensors. So this report is viually useless. If it, by chance, happens to be similar to your old one, its purely coincidence.

Look, because that report is irrelevant because it relates to another motor, we just have to guess what your problems have been.

Now, i am guessing that you have had a bunch of error codes and alarms. The only hints, though, that you have given us are:

1. Dealer says faulty Ecu. The (used) replacement seems no better.

2. There seems to be some question about oil pressure?

So, please answer the following questions, giving specific details:

1. has the oil pressure been actually tested with a pressure tester to confirm what it is? And if so, what were the results? Is the oil pressure good, or not??

2. What, if any, symptoms is the engine exhibiting - not the codes, but what is the engine actually doing or not doing??

3. What parts have been replaced or repaired trying to resolve the problems in question 2, apart from the ecu?



thanks.

Members here are happy to help, but you need to give us at least the info highlighted in red. The report you attached is pretty well useless, as the info it includes relates to the engine that the replacement ecu was attached to, not yours.

If you cant do that, then we cant help you in a meaningful way.

That is a very rude response,
The OP is just asking for some advise not a lecture !!

'''No it's not, what we would like to know is what problems he is currently having with his engine. You have to keep an open mind when reading data pid's. A lot of that data looks simular to what he put up months ago with his old ecu.

[Moonlighter]

Sorry if that seemed ed a bit abrupt, it wasnt intended that way.

It is difficult for anyone to help in a realistic way when the problems being experienced and the assistance sought are dispersed amongst several threads over some considerable time, or are not described reasonably clearly.

That is all that is being asked. Help us, to help you. That's all.

Moonlighter has modified the original post,
It is a bit softer now.

That was after Red posted.

Anyway lets drop the distraction. And get back on topic

Hopefully some further details will be forthcoming that tells us the story about what is happening in full - then maybe some ideas might come forward to assist the OP.

waiting...

I have requested all paperwork from mechanics due to files being lost. I will update further upon receiving.

How can a ECU be reset/Cleared? If you all are saying it is reading OLD data than there should be a way.
