Tips: What is diagnostic code?
Automobile diagnostic code is the fault code reflected by the analysis of the car computer ECU after the car has a fault. Generally,  diagnostic code is caused by the malfunction of the sensor fault sensor, but some mechanical fault cannot be read by ECU.
When the automotive engine fails, the diagnostic car code reader will display the fault code after detecting. Through the fault code, the car mechanic can accurately find the faulty part and then repair it.
There are two types of automobile diagnostic codes: One is accidental fault code, the other is actual fault code.
Usually accidental fault codes can be cleared as long as they no longer appear, but if it is an actual fault code, it must be repaired before it can be cleared.
Besides, when the following conditions occur on the circuit, the fault code cannot be called through the self-diagnosis system:

1. The circuit connecting with the ignition switch, ECU, fault warning light (CHECK), and communication interface is open circuit or shortcircuit.
2. The self-diagnosis output signal is abnormal due to ECU failure.
3. Failure warning light (CHECK) and communication interface are damaged.
