Checking Airbag System Operation

Checking Airbag System Operation

1. Functional check of airbag warning lamp
Turn on ignition. The airbag warning lamp must light up for approx. 5 seconds (2.5 sec as of 06/02/92). If the warning lamp remains dim, check bulb and/or supply voltage.

2. Functional check of error memory.
Turn on ignition and pull off fuse for instrument voltage supply for approx. 30 seconds. The airbag warning lamp must indicate an error. Read on error and check if error code 30 (airbag warning lamp: signal implausible error not present) is displayed.

Note
The central warning lamp must light along with the airbag warning lamp if an error is stored in the error memory.

3. Erase error memory.

4. Make sure that no covers, decals or similar items are fitted at the steering wheel and in the passenger airbag area.

5. Check components visually for damage and modifications.

6. After checking the system, confirm the check in the appropriate fields of the warranty and service booklet.
