- 3Have a workshop check the alternator's charging function and the voltage supply and ground to the airbag module
- 4After the work, switch the ignition off, switch it on again and see whether the code is gone
- 5Do not work on the airbag system yourself; have a workshop carry out all wiring and control module checks
