Sending my ECM today. Hopefully this does the trick. For years I’ve seen folks in blogs post that they developed misfires and then a large plume of smoke out the exhaust. I always assumed it was a head gasket leak or turbo failure. This makes a lot of sense. Probably the easiest part I’ve ever removed from this saab.
We will be following up once we recieve it!

You make it look easy, but it takes practice. I've soldered with an iron since 12 but struggle with this stuff.
If I have the following errors: P1682 P0638 P0606, will the same IC chip need to be replaced?
No that will be a different fault most likely due to one of the big BGA type processor chips
I got the p0204 p0203 p0201 and p0245. All those point towards a fried ECU from what im reading on forums. I may send you my ecu asap.
We should be able to fix that for you no problem. Also, we have been improving our service and repair for this unit and are doing a lot more than what is in the video. If you send in your unit, we may in fact do a more advanced repair video showing some of the additional repairs required to ensure long-lasting functionality.
PS We do offer a 1-year warranty on all repairs.
Does this work for the ones made in France? Mines a 07 9-3 2.0T. Also does it work for the turbo motor as well?
Yes I believe they are designed the same way and have the same faults.
In order for this repair to last (you might get lucky without doing it though), the mofsets for the injectors and the ignition coils need to be replaced too. Being these have a thin film PCB and live on aluminum, replacing those are a bit more difficult. Also, you should make sure when doing these the customer replaces the plugs and coils and perfoms the ecm relocation procedure. Good luck.
Hello,
Thank you for your comment and providing valuable information. Which are the mosfets for the injectors and ignition coils? I see about a dozen components in the TO-252 package but am having a hard time finding info on them from their markings. I assume those are the mosfets you are reffering to?
please givemore detail on this repair,what is the relocation procedure? is this for b engines that get overheated or others down at headlight that corrode?
This is not the issue with these ECUs at least not 99% of them .. u will need to report back if the car was fixed after that which im sure not .
The customer confirmed it fixed it.
Devices can fail in different ways, If you have more information to provide on common faults, please do so I would love to hear you provide more information as to what else goes wrong with these.
Actually I think I was the actual customer. It did repair it and was working for about a month. Then it failed again. I returned to Nick and had another chip soldered in. That also failed after a short time.
@@NicksTVRepair
Sounds like you may need to replace the fuel injectors because there might be a bad circuit.@@ClarkYoung-zl1ne
@@ClarkYoung-zl1nethere is allegedly something "upstream" that causes the real issue. Trying to gather more info
@@TheCarpenterUnion Let me know what you find. I would be happy to do an amendment video correcting any info provided that is not correct or adding any additional missing information.
What flux and liquid solder do you use? HDMI ports on game boxes are money makers too.
We use the Kester leaded solder, as for the flux, I don't remember the code on it. Ill have to find out.
Tried this, it needs to be placed perfectly. Destroyed my ecu. Was told it's nearly impossible to do it how shown here.
Hi. My ECU is throwing the codes you mentioned: po201-204, po245 and po300. Is it likely that chip(s) are fried?
That's a possibility yes
Who doesn't reconformal coat a PCBA? 😂 Hopefully you did! I always do when i fix them because the lid is damaged and well moisture.
There's an expert to warns this is a 1-month solution at best, which would explain why it's already been replaced before. Any comment?
Yeah I have had some good long term success with this repair on some modules but also had several which only worked for a couple weeks or months as you mentioned. Some seem to have long term success while others don't.
Is it a forum post or video? Would love to learn and hear more about this. Do you have a link to this expert warning?
Hi Nick. My daughter's 2006 Saab 93 has a mid-throttle misfire. Driving down the highway...it runs fine. Give it partial throttle, it stumbles and shakes. Floor it and it goes fine. We installed new Bosch plugs and new coil packs. While the CEL is out now, in the past, she had the P0201 code. Does it sound like the ECU could be the cause of the problem? If so, what is your turnaround time?
I am sorry this one seems like there may be more at play and would have to recommend you find a local shop that can take a look at it. Unless it's currently and actively throwing P0201, P0202, P0203, P0204, P0245, or P0300 then I won't work on it.
3-5 business days is the typical turn around time.
Hi Nick, a lot of people in the Saab forums are saying a code P1682 is a bad ECU also (stalls at when idle and/or won't crank intermittently). What's your experience with that code?
That sounds like something wrong with injector #1. Bad wiring/connection or perhaps a dirty or bad injector.
@@WildwwillJust seeing this! I'll check that out. It really does sound specific. Also, heaven forbid I fill the tank up... it'll choke right away and stall out. I replaced the purge valve (found out the old one was fine -- I could not blow through it) and I replaced the gas tank).
HINT: In many cases, injector errors (i mean p0201, p0202, p0203 ....) are not caused by tpic.
Yes that is correct, it's almost always the processors on the lid that are at fault. I did put up a follow up video highlighting this.
This video shows the very first of these units we ever worked on. The follow up video is after fixing dozens.
When you put the ship into the top do you have to program the chip any time
No programing needed on that chip
Is there any way i can get in contact you to see if we can get a repair on my ecu i have 2007 9-3 and had recently got a p0606 code and im really dont want to let this car go to waste😢
I don't think I can help you with that fault. P0606 is not a fault we can typically service. I would recommend either contacting a different company that can fix these that might have a bit more insight on servicing that failure, or trying to get a used replacement ECU on eBay.
Would u do this if send u my ecu , also I have gate driver chip that needs replaced,
Hello John,
Yes we do have a flat rate service which comes with a 1 Year warranty on the repair. Checkout the video description for links to our website and the service listing. If you have any questions, don't hesitate to reach out directly to our support email or you can fill out the contact form on our contact us page.
Friend, could you share the ecu diagram with me?
Sorry we don't have any diagrams, schematics, or anything of that nature on 99.9% of everything we fix.
What can I do about p1681? Please any help is greatly appreciated!
I am not familiar with that exact code, however I would be very interested in learning about it. If you are able to identify the fault could you reply back to this comment and let us know?
The car is a 2003 Saab 9-3 I was getting the full enchilada of codes being thrown p2135, p1681 and all of the above codes for the injectors and and stuff. I believe I’ve resolved the 2135/1681 from the info I gathered they are both related to the tps sensor on the throttle body and/or the accelerator pedal itself, so I replaced both and they haven’t come back but the rest of the codes are still very much there. I’m interested in sending the ecu to be repaired if you are available.
Hey how come you don’t work on codes p0606 I was getting those codes p0300 p0638 p0202 p0245 p0201 after I replaced the injectors only codes p0300 p0606 p0638 & p01312 popping up now I don’t know what to do
That's ECU faults, from my understanding one of the processor chips is malfunctioning. Those are a whole different ball game for repair.
@@NicksTVRepair is it possible you may know someone that can repair it ?
@@adotrp We are currently looking into providing this repair but aren't fully set up for that yet. We will do another video on this repair once we do.
I have the 06 stop with the 4-cylinder Turbo the 93 it's acting like what everybody describes
Es necesario tener un archivo de respaldo con toda la información de tu ecm de otro modo el auto no encenderá más suerte
Hi there? What hot air temp is used? Im struggling to desolder ic chip. Flux is used, a lot..
425C but you don't want to stay on it very long at that temnp. If I have issues with removal I will add leaded solder to all of the joints first to help and also you can use both solering iron and hot air at the same time if only hot air doesn't do the trick. In this video the chip had been replaced prior so it was a lot easier since all of the solder was leaded.
@@NicksTVRepair Tried 430C and nothing, even did some reflow with classic solder hoping it will help. Im struggling with motorola chip next to the tpic.
I will try and add some solder as You advice.
HI NICK, the FET to the left on the processor 307 B 360 , i need one of those. when i use the number and google it, i get nothing. how would you source this chip. thanks.
I have one of these in front of me right now, and I see exactly the component you are referring to but indeed the only markings I see are 307 B 360.
I also am unable to find any type of information about it.
The only thing I can tell you is the package type and it looks like it is a TO-252 but that won't be very helpful if we don't know what it is.
I assume it may have been accidentally damaged during the opening? Your best bet may be to find a replacement module for parts and scavenge off the donor.
OnSemi makes the BJT. It's available at Mouser and DigiKey.
Can i have your contact information so you can fix my SAAB ECU, i also bought that chip just someone to salder it
Hello,
We try to avoid putting contact information or links in the comments, all of that information can however be found in the video description.
Was wondering if you can repair my ecm on a 2006 saab 9-3 2.0 turbo im getting codes P0300 and P0606
Those are codes we have not yet been able to service. My understanding is that those codes are due to either damaged wiring, a bad ground connection, or a faulty ECM/PCM. If the ECM is defective it can be due to bad connection of the processor to the PCB. If that is the case, it would be a very advanced and difficult repair.
I would first recommend confirming the issue is definitely with the ECM and once you can confirm that, fill out the contact form on our website or contact us directly to our support email. The info for our contact info is in the video description. We can go over option with you from there.
What was your luck i got the p0606 code today to buh i did get hard code to and it was my throttle body so im not sure what to tackle especially with tight money
@@Keychaincustoms._43 From what I understand one of the processors fails due to cracked solder joints and causes this code. We haven't performed that repair to this specific module but have performed those repairs to many other electronics in the past. We can give it a try with your module if you would like but I would recommend you email us directly first and we can discuss option further from there.
@@NicksTVRepair like craked solder as in the ecu
awesome video, how much do you charge for the soldering job?
