Theory Of Operation
The location of the right side impact sensor 2 is in the C-pillar area just past the second row seating. Impact sensors perform their own self test using power supplied by the Occupant Restraint Controller (ORC) then communicate this status back to the ORC. The repair of this fault centers on verifying the integrity of the sensor's internal circuitry and software validity. If the scan tool shows this DTC has a Stored history of setting then the right side impact sensor is to be replaced. A short to voltage fault on the right side impact sensor 1 sensor wiring can cause a loss of comm impact sensor 2 code to set and the possible replacement of a good right side impact sensor 2. The right side impact 1, and 2 sensors are wired in a daisy chain pattern. The short to battery fault in a loss of comm or internal circuit failure of the side impact sensor 1 can cause the impact sensor 2 on the same side to set a loss of comm code.
