Airbag error code 19

[996noob]

I recently got an airbag error code 19 on a 993, description is "Airbag Warning Light", which I assume is the airbag warning light itself is faulty. This seems strange since the Airbag light is lit, which is what led me to retrieve the error code to begin with.

Doesn't this seem strange? Any thoughts?

Fault code 19 -- Airbag warning light leakage resistance / short to positive or open circuit

1. Check fuse for voltage supply of monitoring and warning lamps lamps in clock.

2. Check bulb, replace if required.

3. Check wire from triggering unit pin 7 to warning lamp for continuity or short to positive.

Even though the bulb is lit it might not have the impedance or current draw needed for the circuit so it's recommended to replace the bulb, clear codes and retest.

Thanks to both for your excellent replies. This makes perfect sense. I will try a new bulb, and if it is still a problem, check wiring as Loren suggested.

I have a question about the option in the tester to "Lock" the airbag. What does this do? And, if locked, can you unlock it?

Did some reading and I will go ahead and answer my own question, for anyone who might have the same queries as me.

General Notes from 993 TSB 4/98 6863 : "Airbag control units are supplied from the Parts Department in an unlocked state. If a newly installed airbag control unit is unlocked, the airbag warning light will flash until it is locked. A flashing airbag warning light is NOT an indication a faulty condition with the airbag control unit! Once locked, the airbag control unit cannot be unlocked! Therefore, the proper vehicle type must be confirmed before locking. After locking, it cannot be changed."
