call the dealer to diagnose this vehicle for you i will not give out this sort of information ,make sure you have the vehicles papers in your name and the chassis number stamped inside the chassis aligns with the paperwork,then dont forget your`passport or ID card and your fingerprints when taking the car to the dealer as all this will be required

The first step here and on any car with an air bag light is is to have the computer scanned to get codes out.The computer will store a code when it detects a problem with the system, the code will help to locate what part of the air bag system has failed. for example there could be a code that reads b1234 pass/side buckle circuit fault, this code would tell us the problem is in the passenger side seat belt buckle, then with some testing the problem would be found. start by having the codes read, record and write back with codes , also including year,make ,model. good day
