16.3.1 Directly use fault light (F1) flashing on the instrument for

diagnosis.

After confirming there is a fault, if open and close the key for three times switch three times, namely, open —

close—open—close—open the key, the fault light will come to a flash code corresponding to the fault. And

then through the fault code table identify the corresponding fault.

With fault light reading fault, the rules of the flash code are as follows, for example, if the fault is the intake air

pressure sensor is disconnected or the signal-side pin shorts to battery negative, after the key is opened and

closed for three times the fault light will first flicker for 10 times on behalf of 0, flicker for 1 times on behalf of

1 after an interval of 1.2 seconds, flicker for 10 times again on behalf of 0 after an interval of 1.2 seconds, and

after an interval of 1.2 seconds flicker for 7 times on behalf of 7 , namely, P0107.it is thus clear that other

figures from 0 to 9 are expressed by the times of the flicker of the fault light except that figure 0 is expressed

by flicker for 10 times. If there are other fault codes, such as fault P0201, which means there is a fault in the

front cylinder injector, the fault light will continue to flicker P0201 fault code in 3.2 seconds after finishing

P0107; if there is no other fault, the fault light will flicker P0107 and P0201 circularly, and then check the fault

code table for related faults.

While using PCHUD software, the software will use the decimal number to report fault code, and in fault code

table decimal system is corresponding with hex one to one, so the corresponding fault can be found according

to the correspondence between them. For example, in software MULFCURR (current fault) = 263, and it

corresponds to P0107 in the fault code table, namely, the intake air pressure sensor fault.

16.3.2 Make use of diagnostic equipment for fault diagnosis

Operational approach:

1. Locate the 6-hole diagnostic interface on the enginecycle;

2. Connect the connecting wire and diagnostic equipment interface;
