Airbags are a type of inflatable restraint used in automobiles. They were first introduced in the early 1970s and have since become standard equipment in most passenger vehicles. Airbags are designed to provide a cushioning effect in the event of a collision, absorbing some of the impact energy that would otherwise be transferred to the occupants of the vehicle.
RSCA OFF is a feature that is available on some newer Toyota and Lexus vehicles that allows the airbags to be turned off. This can be useful in situations where someone might be sitting in a position where an airbag deployment could cause injury, such as a small child in a rear-facing car.
Roll Sensing Curtain Airbags Off Indicator [RSCA] is a warning light on the instrument panel that indicates a problem with the curtain airbags. The curtain airbags are designed to deploy in a rollover accident to protect the passengers from being ejected from the vehicle. If the RSCA OFF light is illuminated, it means that the curtain airbags will not deploy in a rollover accident.
This is a serious safety issue because curtain airbags are one of the most important safety features in a vehicle. If you see the RSCA light on, take your vehicle to a dealer or qualified repair shop as soon as possible to have it repaired.

2. A problem with the airbag control module
The airbag control module is the computer that controls the airbags. In case there is a problem with the airbag control module, it will trigger the RSCA light.
A problem with the airbag control module can often be caused by a faulty connection. When you suspect that this is the problem, you can try checking the connections to the airbag control module.
3. A problem with the curtain airbags
