Passenger seat SRS alarm

Hi there,
I have a 05 with an SRS alarm on the dash. according to the garage the passenger side pre-tensioner resistance is high. I have buzzed out the wires and connector all are ok. does anyone know the resistance values of the pre-tensioner so I can take off the connector and put in a dummy load to check out the system.
Any help or info gratefully appreciated
cheers
