Hello & Welcome to JA,
The first thing you will need to know is diagnosing this problem is what fault is set in the computer. You will need someone to scan the vehicles restraint system for fault codes & to view the data parameters of all sensors.
There is no danger of the system deploying an air bag accidentally. The cost to diagnose this would be 1.0- 1.5 labor hrs , there are many sensors & circuits that can fail. This is not a computer reset situation.
