The Airbag Simulator is connected in place of the charge (module) and simulates its electrical resistance, which
can be checked using LaRa-AS (109000).

Connect the Airbag Simulator and perform a reset:
• if the system resets itself, the error was related to the module
• if the error persists, check the related electrical wiring harness
Replace the control unit each time the error codes relate to crashes as it cannot be reset. In the case of a sensor
error or side airbag error, the control unit can only be reutilized one more time.
