Hello,
I have the airbag warning light on my Fiat Doblo 263, year 2019 (recently purchased).
1/ The airbag has one DTC inside (B0127-43) but I do not understand its meaning, MultiECUScan is just mentionning "Special memory" ?
It is also reported as "intermittent", so I am not sure this is the reason for the airbag warning light ?
2/ I checked the wire harness and the driver pretensionner and everything seems OK. However, when reading parameters with MultiECUScan, the "pretensioners cut-in counter" = 1 .
Does it mean that the Airbag ECU was not reinitialized and this is the reason of the "airbag warning light " ?
3/ I tried to clear the DTC with MultiECUScan, but nothing happens. I got the dialog box "waiting..." during DTC clearing, but then no error message that something failed, and the DTC is finally still there !
Is this due to the SGW module (reported as "present" in the CAN info) ? I would have expected some error message ("no response timeout", "access denied", etc...), instead of nothing at all.
Here is the MultiECUScan log:
