Warning lamp, AIRBAG

AIR BAG:

Schematic:

The airbag warning lamp is on the RH side of the main instrument unit.

A fault in the system is indicated by the airbag warning light coming on permanently.

On normal function, the SRS control module sends a message to the bus to turn off the airbag warning lamp. If this message is not sent, the MIU turns on the lamp. SRS can also in certain cases send the light message on the bus. This ensures the lamp is lit as quickly as possible.

The central warning lamp is lit as the same time as the airbag warning lamp and at engine speeds higher than 300 rpm, the MIU sends a request to SID to activate the acoustic signal.

When the ignition key is turned to the start or drive position, the airbag warning lamp comes on for 3-4 seconds before then going out if no trouble codes are stored.

If there are trouble codes stored, the lamp will light for 3-4 seconds, then go out for half a second, and then come on permanently until the ignition is turned off or the trouble code is cleared.

If an airbag or belt tensioner has tripped, the airbag warning light is lit constantly.

Diagnostics
The function has no diagnostics.
