Fault diagnosis and elimination of EFI parts
Caution:
●Once the EFI components are disassembled, the EFI system needs to be reset. F or details, see the service information in this
chapter.
●Fuel pumps, three -in-one sensors, stepping motors, ECUs, etc. are precision parts, such as unauthorized disassembly may
cause damage, and it is not within the scope of the three guarantees for human reasons.
●After disassembling the throttle valve body, apply lint -free cloth or textured paper to seal the air filter outlet and intake
manifold to prevent foreign matter from entering.
1. Dump switch
Fuel cut off
during driving
Can ride
normally
Short-circuit the
black-brown, white-
yellow wires
connected to the
dump switch
Can't ride
normally
Check ECU, fuel
pump, throttle
valve body, etc.
Replace the
dump switch
2. OBD port
The main cable has its own OBD interface, and the
location is shown in the previous section to read the fault
code through the diagnostic Speedometer. Use the
diagnostic tool through the diagnostic interface to read
historical fault codes, current fault codes, clear fault codes
and read ECU status.
The picture above shows the cable end connector
