Basic DTC analysis according to OBD2 protocol standard.

OBD2 or On-Board Diagnostics displays messages for basic group styles. More comprehensible code composition has been standard since 2000. The DTC code consists of five characters and its composition will be shown in this video

Insight into programming

The basic unit for the operation of any computer is the bit. Logic 0 and 1 are expressed by a single bit. Diagnostics The error code is composed of 16 bits. The first two bits define one of the four basic circuits. The video will show you a comprehensive overview of the composition of the error report

Cause of DTC

The Occupant Restraint Controller (ORC) is a sensing and diagnostic module that is responsible for monitoring and managing hard wired inputs, outputs, bussed messages and contains the vehicles Dynamics Sensor. The module contains the pre-programmed logic to determine if and when a restraint is to be deployed. The ORC monitors these systems at ignition on and for most systems, continuously during vehicle operation, communicating relevant status and data over the bus. If the ORC detects a system failure or monitored value that is out of the allowable range, a corresponding DTC will be set and recorded and the Airbag Warning lamp will be commanded on. In the event of a vehicle crash which exceeds a predetermined level, this may or may not include restraints deployment, crash data will be recorded and cannot be deleted. The Early Crash Sensors (Frontal Crash Sensors) are located on the front crossmember. The Remote Acceleration Sensors (B-Pillar Sensors) are located behind the trim of the B-Pillars. The Door Pressure Sensors (if equipped) are located in the front doors and the Yaw and Lateral Sensors are internal to the controller.
