ECU reporting wrong temp, No closed loop

[luigi daniel]

Thank you again ! Sure these help, gold mine !
The car was bought from the US and the VIN is 2CNBJ1869S6920XXX. RPO tag L01. ECM tag shows 33920-70EB 0 E2T42991 M1 4920C A6 US-3AT.
Unfortunatelly, as I am away from home now, I cannot check the engine's plate but I can guarantee it is the original installed. ALL spare parts were purchased from the US even that the costs, per total, already exceeded the whole car's value !
First thing when back home I will check for cracks on exhaust, as per your advise.
Then, another attempt to communicate, by using other hardware and software. Then, I'll know what to do. You have opened a laaarge horizon...

Best regards,
Luigi Daniel

i see all your posts on other forums, all very good.
i see the tech1, books with google. easy.
but no books show the list of cartridges, only this photo.


there are many suzuki ECU used, world wide, and each has its own sensors.
my guess , is lots of cartridges exist , too bad no list exists. or is very hard to find.

the docs warn not to plug your MTS into the wrong DLC conn. or the MTS blows up. ouch'
