| There are many parts that make-up the supplemental | | | | than the blink of an eye the airbags deploy. So to |
| restraint system (SRS) or airbag system. However, if | | | | respond to the original thesis of this article, whether or |
| you are in the process of replacing your car airbags, I | | | | not you have to replace the airbag crash sensors |
| want to concentrate on your car airbag sensors. | | | | after an impact, that answer is... MAYBE. It really |
| DIY'ers and newbie automotive technicians often ask | | | | depends on the severity of the accident. What you |
| me whether the crash sensor must be replaced after | | | | want to take away from this article is that impact |
| a vehicle has been in an accident. However, before I | | | | sensors or crash sensors are reusable. In most cases |
| give you my response, lets look at how airbag sensors | | | | they are located in areas where they are protected |
| affect the SRS system. There are many types of | | | | and therefore can be reused. So, how can you tell if |
| airbag sensors and their location varies by year, make | | | | they need replacing? "Key note", the airbag module or |
| and model. So, my general comments will be that your | | | | SRS diagnostic module (SDM for short), is there to |
| car airbags sensor are located where they can | | | | detect any failures in your car airbags system. So if |
| interpret two variables, a collision and a reduction of | | | | you're in the collision repair business and you are in the |
| speed. Most importantly, both variables must be | | | | process of having to replace airbags. You only need |
| present to activate the airbags. Therefore, some | | | | to replace the cars airbag sensor if your scan tool |
| impact sensors measure vibration and others measure | | | | detects an error codes for that sensor. So, the bottom |
| an immediate reduction in speed, or deceleration. When | | | | line is, airbag impact sensor and crash sensors are |
| both variables are detected the information is | | | | reusable and your airbag module will detect whether |
| immediately relayed to the airbag module and in less | | | | they will need replacing or not. |
