MB w202 c180 SRS light on
Hi,I am a new member and I need help on how to delete SRS light (mercedes w202 c180 1998 38 pin plug).
Had disconnected the airbag and for some reason,I turned the ignition on.After I reconnected the airbag, SRS light remains on.
With the ignition on,srs light comes on.Within 3 sec,it goes off and back on again.
I have made a device according to the schematic given,with a 12 volt LED.
Note. If you buy a 12 volt LED you don't need the resistor.
Procedure given:
Ignition ''on''.
Connectios: black wire to pin 1, red wire to pin 3, yellow wire to pin 30 (Airbag/emergency Tensioning Retractor) .
Hold the button down for 4 sec.(light is on) and then release,(light is off).The light should flash now, in order to read the fault,but remains off.
In turn,I connected black wire directly to chassis.No result, again.
Tried to jump pin 30 directly to ground pin1 for 10 sec,in turn pin 30 directly to chassis, with no response.The SRS light, remains on.
Any other DIY suggestios?
Hope somebody will help me.
Thanks in advance.

Hi Plutoe
Thanks for reply.My English in not so good, so I can't understand, what ''I have been buffled'' means, sorry!
Any way, I found a video on youtube with title ''Mercedes W140 and R129 read and Reset Error codes''. And followed the steps given.This car is equiped with a 38 pin plug too.He uses a device similar to that I found on a MB forum.That's why I tried.But if you'd like to watch that video, perhaps you will advice me, what is wrong with my attempt.
Thanks once again!
