See the basic definition of a diagnostic error. This will help you to clarify the main causes of the fault code. You will understand the program of the control unit
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

Basic error definition

Front Speed Sensor LH Circuit

Cause of DTC

When any of the following is detected: 1. At a vehicle speed of 6 mph (10 km h) or more, an open or short in the sensor signal circuit continues for 1 second or more. 2. Momentary interruption of the sensor signal from the abnormal wheel occurs 255 times or more. 3. An open in the speed sensor signal circuit continues for 0.5 seconds or more. 4. When the vehicle is driven in reverse at the speed of 1.8 mph (3 km h) or more and 3 of the wheel sensors detect the reverse signal, the other sensor detects high frequency pulse 75 times while the engine switch is on (IG). 5. At a vehicle speed of 6 mph (10 km h) or more, the vehicle speed sensor output halves for 5 seconds. 6. At a vehicle speed of 6 mph (10 km h) or more, the direction of wheel rotation changes 7 times in 0.006 seconds while the engine switch is on (IG). 7. At a vehicle speed of 18 mph (30 km h) or more, one wheel direction is different from the other 3 wheels for 1 second. 8. At a vehicle speed of 60 mph (100 km h), a reverse signal is output for 1 second or more. 9. At a vehicle speed of 18 mph (30 km h) or more, the rotation direction of the one of the wheels is not detected normally and the rotation direction of the other 3 wheels is not the same for 1 second. 10. With the IG1 terminal voltage 9.5 V or more, the sensor power supply voltage decreases for 0.5 seconds or more.
