Codes b1650 and b1346
Could your codes be different than mine? I could find anything starting with B, they all started with P.
I found no P1346 code, but found P1650 which is
P1650 Powertrain control module fault (quad driver 2)
This has to do with the transmission and if you have a manual transmission I think it doesn't apply.
If the airbag light is not coming on, this indicates a bulb is burnt out or the airbag control module is bad.
Good luck on this one.
