S40 Airbag wows

nwright6 · Jan 17th, 2012, 23:17

Hi all ran into a spot of bother with my 56 plate S40.
I got the car with front end damage so obviously ive had to replace bonnet bumper headlamps and rad then after all that i had to start on the Airbag system.
After reading a couple of posts on here ive replaced the front crash sensors , passenger and drivers airbag, rotary coupler front seatbelts and drivers seat pretensioner buckle then the SRS ECU in the console.

However the SRS warning keeps coming up on the clocks saying "urgent service required".

I have cleared and read all faults with my mates ethos then when i cycle the ignition i get fault codes come up on the ethos saying

009A rear seat belt buckle signal missing
002 SRS Indicator lamp signal missing
004 pad lamp signal missing
E003 configuration fault faulty configuration
0128 CAN signal. Signal missing
012A CAN signal signal missing

Can anyone help me ??

Is it the wrong ECU??

Thanks for taking the time to read this Neil.

I'm no expert but I would imagine all of the cars sensors will be programmed into the main ECU so chances are the car's ecu will need re-programming to accept all the bits you have replaced.
