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

DTCs P0010 and P0011 are not set -- without LU3. When DTC P0315 is set, the engine speed must be greater than 1,000 RPM. Engine run time is greater than 2 crankshaft revolutions. The engine speed is between 375-5,600 RPM. The ignition voltage is between 9-32 V. The engine coolant temperature (ECT) is between -7 and +130°C (+19 and +266°F). When the startup ECT is colder than -7°C (+19°F), this diagnostic will be delayed until the ECT is warmer than +21°C (+69°F). The fuel level is greater than 10 percent. The ECM is not in fuel shut-off, or decel fuel cut-off mode. The electronic brake control module (EBCM) and the traction control system (TCS) are not active or detecting rough road. An automatic transmission shift with a throttle position greater than 95 percent is not occurring. The power management is not active. Excessive drive wheel slip is not detected. The power take-off (PTO) is disabled, where applicable. The cylinder deactivation is not in progress, where applicable. DTCs P0300-P0308 run continuously when the above conditions are met.
