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

No. 8 Cylinder Misfire Detected

Cause of DTC

The misfire detection logic consists of the following two conditions: One Trip Detection Logic (Three Way Catalyst Damage) - On the 1st trip that a misfire condition occurs that can damage the three way catalyst (TWC) due to overheating, the MIL will blink. - When a misfire condition occurs, the ECM monitors the CKP sensor signal every 200 engine revolutions for a change. - When the misfire condition decreases to a level that will not damage the TWC, the MIL will turn off. - If another misfire condition occurs that can damage the TWC on a second trip, the MIL will blink. - When the misfire condition decreases to a level that will not damage the TWC, the MIL will remain on. - If another misfire condition occurs that can damage the TWC, the MIL will begin to blink again. Two Trip Detection Logic (Exhaust quality deterioration) - For misfire conditions that will not damage the TWC (but will affect vehicle emissions), the MIL will only light when the misfire is detected on a second trip. - During this condition, the ECM monitors the CKP sensor signal every 1,000 engine revolutions. - A misfire malfunction can be detected on any one cylinder or on multiple cylinders. No. 8 cylinder misfires.
