Properly functioning airbags save lives and significantly cut bodily harm in automobile crashes.
Airbags, which are usually located on the Chauffeur and passenger sides of a vehicle, are influential additions to motorcar safety designed to deploy on crunch to diminish bodily harm in the adventure of a machine crash. Airbags are controlled by an airbag control module (sometimes referred to as the airbag machine, corresponding to the "livid box" institute in planes), which is located inside the vehicle. The management module senses when a crash has occurred and at once activates the vehicle's airbags. In the calamity an airbag deploys without a crash, it can be repaired and the imperfection and misconception codes in the airbag module reset. (Descry Reference 1 and Resource.)
Instructions
1. If you don't have a DTC chart, look online for DTC software for your vehicle. This diagnostic information will help you decide the best method of fixing your blown airbag. (See Reference 4 and Resource 1 and 2.)4.
2. Allot your vehicle's airbag authority module. Airbag state modules can be mounted in contradistinctive locations inside a vehicle, including under the Chauffeur or passenger seat, remain the steering path, in the kick panel and under the centre console. Once you hold located the airbag control module, plug the scanner object cable into the ascendancy panel. The scanner tool accesses the memory on the control module and displays the computer codes that are operating your car's airbag module. (See Reference 1, 2 and 4.)
3. Analyze the series of computer codes displayed on the airbag control module and the diagnostic scan tool. Look up displayed fault and error code number (and code description, if available) in a standard airbag code Diagnostic Trouble Codes (DTCs) reference chart to receive information on the faults detected in your car, including the reason your car's airbag warning indicator light is on or flashing. Generate the tools needed to diagnose and allot the blown airbags and the airbag control module, including an airbag curb module scanner item and a statute reader. These can be purchased at most Car parts stores. A law reader is a diagnostic object that can announce and crystal snag codes from your vehicle's machine, while the scanner thing displays method operating counsel and other facts that instruct the workable kingdom of your vehivle, such as O2 sensor outputs, loop status (manage or closed), coolant temperature, airflow, throttle position and fuel trim values. (Observe References 1 and 4.)
Fix and re-program the airbag control module. Order and replace blown control module parts, such as capacitors and resistors. Clear and reset fault and error codes on the airbag control module similar to how you would restore a home computer's hard drive. (See Reference 1 and 2.)
5. Test the re-programmed airbag control module to ensure that the non-deployed airbags will activate with the re-programmed module in an accident. Get into your vehicle and turn the key. Look at the dash to see your airbag light (the airbag light bulb should have been checked during the diagnostic stage). If non-deployed airbags are in good working condition, the airbag light should come on for seven to 10 seconds and then go out. The airbag light should not come on while you are driving. (See Reference 3.)
