hi guys,
i have Volvo S80 2.9L model year 2000 (non turbo) throwing ECM-9150 ETM internal fault (this pulled using iCarsoft 906 scanner) with orange triangle warning light / Engine system urgent message. the car only has 35000 miles. The car drives and no idle issues just have just orange triangle and message engine system urgent.. I have white label ETM no recall update was done by previous owner.
Also, The couple of three weeks ago after filing up gas and coming to stop at traffic. The car suddenly started to spudder and no response to accelerator pedal i pulled to the side street restarted it came back to normal. I replaced the MAF sensor already but no avail and also cleared the DTC code with icarsoft 906 but the code ECM-9150 keeps coming back.

Does this sound like ETM is on its way to going bad? Is this like some kind of early warning from car computer? Can other things cause ECM-9150 internal fault code ? Should i approach the dealer on this or Get the xmodex rebuilt?

 

Haven't run into this problem yet, but here is a troubleshooting guide that may help?
