Fault code analysis steps:
1)
Read and record all fault codes;
2)
Erase all fault codes;
3)
Simulate the conditions generated by the fault and start a road test;
4)
Then read and record the fault code at this time;
5)
Distinguish between incidental fault codes (independent fault codes or
historical fault codes) and persistent fault codes (current fault codes or
associated fault codes);
6)
Distinguish between the major fault code and the minor fault code
associated with the fault symptom;
7)
Distinguish the major fault codes in many fault codes or related fault codes
(it may be the cause of other fault codes);
8)
According to the above analysis, you can further detect the sensor
represented by fault code, related circuit state of the actuator or control
computer, as well as accurate position of the fault occurred.
