Description
The Impact Sensor 1 is located in the B-pillar area. The Impact Sensors perform their own self test using power supplied by the Occupant Restraint Controller (ORC) then communicate this status back to the module. The repair of this fault centers on verifying the integrity of the sensor’s internal circuitry and software validity. The impact sensor performs a self test for internal circuitry at power up during the initialization process, and continuously through the ignition cycle every 10 ms.
This DTC sets when the ORC receives notification of a self test failure within the impact sensor. Once set, this DTC is latched for the entire ignition cycle.
