The ORC determines if a frontal or side collision is severe enough to require the airbags to inflate. Based on the impact sensors signals, a central electronic ORC deploys the front airbags, side airbag inflatable curtains, and front seat belt pretensioners as required for each type of impact. The ORC contains a backup power supply system that may deploy the airbags even if the battery loses power or it becomes disconnected prior to deployment. Also, the ORC turns on the Airbag Warning Light in the instrument panel for approximately four to six seconds for a self-check when the ignition is first turned on. After the self-check, the Airbag Warning Light will turn off. If the ORC detects a malfunction in any part of the system, it turns on the Airbag Warning Light, either momentarily or continuously.
