General

There is a diagnosis program integrated into the control unit (N2/2), which checks the control unit and the airbag system components.

When a fault is detected warning lamp (A1e15):
- does not light up in steering lock key position "1".
- does not go out after 4 s.
- lights up when the vehicle is being driven.

The warning lamp goes out again when no more faults are present; however, the fault remains stored. The stored fault can be called up in the form of a flashing pulse via warning lamp (A1e15) or digitally via a pulse meter.

Test Conditions:
- During pulse output, the test coupling/plug connection for airbag (X29/9) remains contacted.
- Battery Voltage (11 - 14 V).
