This info is the same for all T8 ECMs.
Codes P0201, P0202, P0203, P0204, P0245
with / intermittent hard starting, rough running, white smoke, or over-boosting issues.
We are gonna replace the most common cause of SAAB 9-3 T8 ECU failure: the TPIC46L02 that drives the injectors and the wastegate. There are potentially other bad chips but always start with that one if you are getting all the codes listed above.
If you have different codes than the ones I list above then it’s probably not the chip I am replacing here (see the comments).

You should backup your ECU software using this method.

With those backups, you can reprogram (also remaps) almost any 9-3 T8 ECU to be compatible with yours.

i’ve got a MyMetro SmartRide that gives me the codes in this order for my 2005 9-3 2.0t
P0204 P0202 P0201 P0300
is it not be the chip you are fixing here? if not do you know what it could possibly be?
Thank You
Do you offer the service to replace the chip on the side. I have extra bad ECU in hand from these code.
Hi,where do you get the chip to repair ecu.
great video.
my 08-93 got u2105 and p0601, you know which one is failed？
You are right that fixed my saab. Had to get tv repair shop to solder it in 95 dollers well worth it.thank you
Thanks doe this video. I just bought a 07 9-3 and it has literally these codes. I’m glad to see someone out here who knows how to fix this instead of having to send it to Illinois for 600$. I might be coming back here asking for help soon lol…
Thank you so much for this! Do you know if p0687 is also tied to this chip? My ecm more consistently has p0687 (ecm/pcm relay circuit high) and injector codes will come up sometimes. when they do, the car seems to dump fuel.
What do you mean 12:55. “Maybe if the ECU is marginal. And has to warm up before start to fail” That is happening to my ECU. I will appreciate any help
Do you have to reprogram it after doing this.
Hola con este procedimiento resuelves el problema común de falla en los inyectores ? Saludos
