2006-2009 Saab 9-5
The airbag light is on and DTC B0022 and/or B0042 is present after performing the Takata recall; following WIS fault tracing may lead to a coil spring replacement. We have seen the airbag connectors in the harness in the steering wheel show signs of damage after airbag replacement. The short circuit connector (shorting bars) are not releasing enough when the connectors are fitted together causing this low resistance DTC to set.
Diagnose and repair/replace (as needed) the harness in the steering wheel between the coil spring and airbag. The supply of this harness is very limited; extreme care must be used to avoid damage.
