Technical Resetting Airbag ECU with Multi ECUScan

[typecastboy]

Forgive me for repeating this, as I have put it in the thread about Diary of my Cat C.

I am having trouble resetting the codes in my Airbag ECU. Initially, it said it couldn't connect to the ECU, but then when I press DTS Scan, it shows all the error codes (picture below) but there's nowhere to be able to reset them. I am using the yellow cable connected as normal to the OBD port. I've looked through every part of the software and there doesn't seem to be anywhere to reset the codes.

I do have a replacement Airbag ECU, but people on here were telling me that MECU would reset it. Has anyone actually done this successfully before?

Hi,
in Multiecuscan revision 2.7 you connect to the airbag ECU, press F3 or click on the "Errors" button, Then press F10 or click on "Clear Errors" button (bottom left).
I think you may just be clicking the DTC Scan button. Connect instead using F10 or the "Connect" button.

HTH,

I connect to the body I think it says! There's no button to specifically connect to the airbag ecu!

Hi,
When you select your vehicle in MES there are "system" and "control module" lists. Select "Airbag" in system, "Continential...." in module and then click connect.

He says so "I am using the yellow cable connected as normal to the OBD port."

Yellow is the A3 colour and required for airbag on a 500.

OMG I'm such a pillock. I've just realised after booting up the laptop that under System there was a scroll bar with ABS, Airbag etc. I feel really stupid now. I'm actually running V2.4. I imagine I can update, but will have to pay again?

I've now downloaded 2.7 and according to the website it's a free upgrade for registered users. Happy days. Thanks for your help. Can't believe I was so stupid!!!

Just out of interest, can you connect directly to an airbag ECU or does it have to be installed in the car?

Hi,
I don't see why you can't connect to an ECU on it's own. You would need a connector and power supply. It would also show lots of faults unless you built a rig to simulate all the inputs. Easier to just plug it into the car.
