hi guys i am new in this forum
i bought s40 t5 2005
the dime show srs airbag service urgent
i checked all the cable under the seat with multimeter all was ok
i tray disconnecting the battery for 30 min and put key in position II and connect it back or connecting ground to live and......
still noting
i connect my vida dice 2013a to car and read the car and there is no fault
i select srs and try to erase it but still the light is on
here is the pictures !!!
i know many people gone say is srs module but how can i be sure is srs module??
any idea?

Yeesh! I just don't see how your DIM can think it needs to tell you "SRS Service Urgent" without setting any fault codes.

Are there NO fault codes set for anything? AFIK, the "SRS service Urgent" comes on after a fault anywhere in the SRS system. This includes the following (off the top of my head, probably more):

• The SRS light in the DIM
• Seat belt pre-tensioners,
• Air bags
• The SRS module itself

The actual fault can be as slight as a blown LED or broken wire.

The whole low side of the network is down. That's why the SRS light is on.

ok i tray to read the code and reset srs with another code reader it give me
1: srs-cfff control module internal fault
2 srs-0005 power supply from battery voltage is too low
3 srs-0003 pad lamp faulty function
4 srs-cfff control module, internal fault
5 srs-e001 control module communication. faulty communication
6 srs-0002 srs indication lamp. signal missing
then i tray to clear srs code and the code reader didn't do it
after that i install Volvo dice on my other laptop and scan the car this time the dice give me the code !!!!!!!
the phone ring and i had to get back inside and disconnect my laptop after i get back about 10 min i tray to scan the code again with dice and dice don't show me any fault !!!!!!!!!!!!

My first response would be to clean and rebed the connectors (dielectric grease?), especially the ones to the main fuse block under the glove box. Otherwise, start looking the confirm that low battery voltage. Everything else could come from that.

i bought second hand module and gone to volvo dealer .they said because is my first time there they gone do free diagnostic . they said is my module when i ask them to program the other one they said is not possible !!!!!!they said once the software been install on module {burn on module } they can not replace the software !!!! many people the said volvo reprogram the module !!!! are the volvo lying to me ? by the way the said they need to order new one which cost $750
