2.2.7.6 DTC Code Type Definition

Fault Type

Definition

Type 2

Fire-related troubleshooting is generally defined as type 2. For cause of damage to catalytic converters
Misfire MIL flashing lights to warn the driver immediately. With the emission deterioration fault caused
by misfire, if the corresponding level of misfire is fully detected in three consecutive driving cycles, the
MIL lamp is lit. The fault will be deleted after 40 continuous trouble-free warmed-up driving cycles.

Type 3

If a fault is detected in consecutive three driving cycles, the MIL lamp is lit. If the fault has been repaired
after 3 consecutive driving cycles, the MIL lamp will be off. The fault will be deleted after 40 continuous
trouble-free warmed-up driving cycles.

Control System JL4G18-D

2-49

Type 4

The MIL lamp will be lit in 2.5s when a fault occurs. If the fault has been repaired after 3 consecutive
driving cycles, the MIL lamp will be off. The fault will be deleted after 40 continuous trouble-free warmed-
up driving cycles.

Type 5

A fault is confirmed after it is detected in 3 consecutive driving cycles, and the fault lamp will not be lit.
If the fault is detected as repaired after 3 consecutive driving cycles, the fault has been repaired. The
fault will be deleted after 40 continuous trouble-free warmed-up driving cycles.

Type 6

The fault is confirmed as soon as it occurs. The fault will be deleted after 40 continuous trouble-free
warmed-up driving cycles. This type of fault does not trigger any lamp and is not readable by a universal
scan tool.

Type 7

External testing tools activate the external fuel supply system fault diagnosis path. It is generally used
in offline inspection or in a repair station. This type of fault does not trigger any lamp and is not readable
by a universal scan tool.

Type 11

It is dedicated to fuel supply system diagnostic path. If a fault has been detected in 3 continuous driving
cycles, the MIL lamp will be lit. If the fault is detected as repaired after 4 consecutive driving cycles,
the MIL lamp will be off. The fault will be deleted after 40 continuous trouble-free warmed-up driving
cycles.

Type 35

To identify and repair the fault is through timing. To remove the fault from the memory needs 20 driving
cycle. It is generally readable for a universal scan tool abd triggers flashing MIL lamp.

Type 38

To identify and repair the fault is through timing. Removal of the fault from memory is triggered by time.
It is generally readable for a universal scan tool
