Default Engine Service Required msg but NO check engine light

Hi, Gang. I've searched the forum for an hour and have given up and will just post this. Hope it's not ridiculously redundant.

I had a Check Engine Light (CEL) and an Engine System Service Required message. I had an ECM-9150 relating to the ETM (throttle body). I took out the ETM and it was dirty so I cleaned it really well. After reassembly the Check Engine Light is off but the Engine System Service Required message is still on. If my cleaning didn't do the job why is the CEL still off? Can I turn the message off? I need to pass emissions.

Thanks

Dan

I ran the diagnostics with the read button and it says there are ECM DTCs. So, I'll have to rescan them. My question really is why is the Check Engine Light still off if there's codes? I called Volvo and they said there are some codes only THEY can remove.

The drama continues. I scanned with an OBDII scanner and there are NO CODES. Think it will pass emissions?

If there are no OBDII codes and your Readiness codes are set you should be good.

I just passed emissions. Stupid message is still there, though. Maybe it'll cycle off. I wish Volvo would mind their own business. Thanks all for listening to my little melodrama.

I have 2001 s80 Have been getting that message for 6 months It will stay on about 100 miles and go off for about 300 miles then back on. No CEL has ever come on and have no codes. I am starting to get some surgeing at 2000 rpm Throttle body replaced at 94000 miles now have 144K Going to have TB recleaned and see if this helps

Maybe it comes on every 300 miles because Volvo's never seen one of their cars that didn't need something within 300 miles That might be a little harsh but I really hate voodoo car symptoms.

If you have a reading of ECM-9150, you have an internal fault with your ETM.
Hopefully you can have it replaced under the extended warranty of 10 years/ 200,000 miles.
I had a simialr fault, with no CEL on, and the dealer replaced mine at no charge.
Good Luck.

Yeah, I know. Since it's a 99 S-80 we missed the boat on the recall replacement. My girlfriend doesn't remember getting any notice in the mail but it doesn't matter now. The car passed emissions and now I know how to replace an ETM so I'll just wait for complete failure and replace it myself. I saw them online for $299/$100 core. An independent Volvo joint wanted $995 for a replacement.

Final Update. My girlfriend called me on her way to work today and said that the messages and the orange triangle are gone. Evidently, they cycle off after a time. Her dashboard is light-free. End of story. Thanks all for your help.
