1992 400SE

I checked for any codes in the various W140 pulse counter systems.

I cleared all the codes in the many systems to see which return, but once I got to the SRS (pin 30) I got these codes:
3-Driver Air Bag
4-Front Passenger Air Bag
8-Circuit 15R, Voltage Supply
9-Warning Lamp Fault

It would not allow me to clear any of these codes. The SRS light on the cluster comes on during starting, but goes away as normal & never comes on while driving.

Does anyone know how further diagnose this problem? I don't wanna find out I don't have airbags in a worse case senereo (knock on wood that it never happens).

If the light isn't on when driving the system should be happy...
