Theory Of Operation

WARNING: This page is about a different car, the 2016 Jeep Wrangler and 2015 Jeep Wrangler. However, it is still accessible from the selected car via links, so may be relevant.

The location of this right side impact sensor 1 is in the B-pillar just past the first row seating. Refer to DESCRIPTION . The impact sensors perform their own self test using power supplied by the Occupant Restraint Controller (ORC) then communicate this status back to the ORC with periodic updates. The repair of this fault condition involves verifying the integrity of the wiring between the ORC and the sensor. 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.
