Fault diagnosis
ECU only implements fault diagnosis for the fuel injector
drive stage. When the fuel injector drive stage is short-
circuited or overloaded to the battery voltage, short-
circuited to the ground, or open circuit, the fault fl ag is set.
At this time, close the closed-loop control of the oxygen
sensor and its self-learning pre-control. The last self-
learning data is valid. After the fault is removed, the fault
fl ag is reset. Common fault codes are shown in the fault
summary table
◆
Injector failure inspection:
◆
Check the connectors are well connected
◆
Check whether the wiring harness and injector pins
are bent or deformed
◆
Check whether the injector cap and the oil pipe are
reliably connected
◆
Unplug the connector and check the coil resistance
between pins

and

◆
Check the resistance between the pins (

◆
Check the resistance between the pins (

!
When removing the fuel pipe, there is high-pressure fuel
in the fuel pipe. Pay attention to fi re safety and spray it
into your eyes carefully.
