CEL up, Vida out, I dont know what to think of it..

[ThomasG]

Literally- i dont know what to think.
maybe because my mind is occupied by something else.

anyway- i was in the middle of that "something else", doing my rounds loaded with tools, when CEL popped up.

no misbehaviour from the car at all. just the light.

made it home, pulled out DICE and laptop, as for first time using it i think i did good..

God (of your choice) knows when this car was read/codes erased last time, if ever..
so most of stuff above can actually go to bin..
whats disconcerting- i cant see any reason for CEL!
and yet its up..

so.. erase codes, do as instructed (engine off, engine on, rev to 1500, idle, engine off, engine on, idle for 30 seconds) read codes again (CEL is gone!)

CCm-0021  Air quality sensor internal fault
CCM- E003  Configuration fault, faulty configuration

I dont know what to think of it..

what the hell was that CEL?

me thinks the only thing i can do is to go, drive again, and see if it comes back.

then read again?


Notes:

UEM-004 yes, siren is faulty
UEM-003D in addition to bulb, i fitted extra LED strip along line where plastic trim meets fabric of the roof

UEM-0080 strangely wipers work mostly fine.. sometimes theres a hesitation when stopped in traffic in very light rain

From what I have read on this forum over the last few years, what you describe has happened to your car is not that unique....V70/S60 of the age this forum section covers do strange things electrically.
Reading, then clearing the DTC codes with VIDA/DICE would appear to be the No.1 go to "try this first" advice when electrical gremlins strike.
Another reason that the VIDA/DICE setup should be in the tool kit.
