How to fix a Code 34 airbag issue on a Ford E250 4.6L 2006

Hello, flash out code 34 refers to the passenger front seat belt pretensioner circuit. Testing will be needed in that area to find out what is wrong. Note that a "B" code will be in memory in the restraint control module which may also be helpful, testing is required with a diagnostic tool that can retrieve body, chassis and powertrain codes. Could be as simple as a disconnected wiring connector under the seat (possibly from debris under the seat), to a pretensioner problem, to another wiring issue. Due to the safety related special concerns with the air bag system, suggest professional assistance.
