5.3.9. Airbag indicator light

The airbag indicator light is located in the instrument cluster. Crash Safety Module system operability is indicated by the airbag indicator light lighting up and then going out during the pre-drive check. The airbag indicator light is controlled by means of a message on the PT-CAN from the Crash Safety Module. The instrument panel receives a message on a cyclical basis. If the message fails to arrive, the airbag indicator light is activated.
