Raider 2WD V6-3.7L (2008)
The ORC also contains an energy-storage capacitor. When the ignition switch is in the START or ON positions, this capacitor is continually being
charged with enough electrical energy to deploy the SRS components for up to one second following a battery disconnect or failure. The purpose of the
capacitor is to provide backup SRS protection in case there is a loss of battery current supply to the ORC during an impact.
Two sensors are contained within the ORC, an electronic impact sensor and a safing sensor. The ORC also monitors inputs from two remote front impact
sensors located on the back of the right and left vertical members of the radiator support near the front of the vehicle. The electronic impact sensors are
accelerometers that sense the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. On vehicles equipped
with optional side curtain airbags the ORC also monitors inputs from two additional remote impact sensors located on the floor panel just behind the
front seat crossmember beneath the outboard side of the left and right front seats to control deployment of the side curtain airbag units.
The safing sensor is an electronic accelerometer sensor within the ORC that provides an additional logic input to the ORC microprocessor. The safing
sensor is used to verify the need for a SRS component deployment by detecting impact energy of a lesser magnitude than that of the primary electronic
impact sensors, and must exceed a safing threshold in order for the airbags to deploy. Vehicles equipped with optional side curtain airbags, feature a
second safing sensor within the ORC to provide confirmation to the ORC microprocessor of side impact forces. This second safing sensor is a
bi-directional unit that detects impact forces from either side of the vehicle. Pre-programmed decision algorithms in the ORC microprocessor determine
when the deceleration rate as signaled by the impact sensors and the safing sensors indicate an impact that is severe enough to require SRS protection
and, based upon the severity of the monitored impact, determines the level of front airbag deployment force required for each front seating position.
When the programmed conditions are met, the ORC sends the proper electrical signals to deploy the dual multistage front airbags at the programmed
force levels, the front seat belt tensioners and, if the vehicle is so equipped, either side curtain airbag unit.
The hard wired inputs and outputs for the ORC may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring
information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the ORC or the electronic controls or
communication between other modules and devices that provide features of the SRS. The most reliable, efficient, and accurate means to diagnose the
ORC or the electronic controls and communication related to ORC operation requires the use of a diagnostic scan tool. Refer to the appropriate
diagnostic information.
