2005 TOYOTA SIENNA with 171000. miles

2005 Sienna, srs airbag light came on while driving. Vehicle has not been involved in a crash. Connectors were checked and were secure. Ran scan on srs with innova 3150 and received error code B0101 "open in d squib circuit". After researching online, it seems to be a common problem in the 2005 and 2006 models. There should be a recall. Some dealers just want to replace the entire airbag system, which is an expensive solution. This is a huge safety concern for Toyota.
