Obd Interface; Fuel Pump; Canister Solenoid Valve - Zontes ZT368K 2025 Maintenance Manual

2.OBD interface

The main line cable comes with an OBD interface, and the
location is shown in the previous one, and the fault code is
read through the diagnostic instrument. The diagnostic
instrument can be used to read historical fault codes, current
fault codes, clear fault codes, and read the status of the ECU
using the diagnostic interface.

3.Fuel pump

Note:
●The fuel pump is a precision component, which needs to be
assembled in a dust-free workshop and requires strict testing,
so it is forbidden to disassemble it by yourself.
●The engine of this motorcycle is designed with a high
compression ratio, it is recommended to add 95# and above
unleaded gasoline for a long time, in order to prolong the
service life of the motorcycle, please be sure to refuel at a
regular gas station.
●It is forbidden to carry out the operation test of the fuel
pump in the dry state or in the water, otherwise its service life
will be shortened, and in serious cases, it will be directly
damaged. The positive and negative wires of the fuel pump
cannot be reversed. It is forbidden to disassemble the inlet
filter, which can easily cause foreign matter to enter the fuel
pump or block the injector.
●Dismantling the fuel pump or high-pressure oil pipe should
be carried out in a well-ventilated, dust-free or dust-free
environment; Dangerous operations such as fireworks or
mobile phone calls should be strictly prohibited in the
dismantling site.
When there is difficulty in engine starting or dust-free
starting; Poor engine work, unstable operation, etc.; The
injector does not inject fuel; When the engine is running
weakly and the acceleration performance deteriorates, it is
necessary to check whether the fuel pump is abnormal.
Dismantle the surrounding floor and high-pressure

tubing. Use an oil pressure gauge to measure the fuel pressure,
or a simple test method to test whether the fuel pump is
healthy.
If you need to remove the fuel pump from the vehicle, you
can use a siphon pump to drain the fuel from the fuel
tank.After lifting the vehicle, press the plug clip as shown in
the diagram to disconnect the wiring.Using a 10mm socket,
remove the 5 bolts from the bottom, then remove the high-
pressure fuel line bracket. Once the bracket is removed, the

fuel pump can be taken out.

Note that you should not press the outlet pipe shown in
red, and once damaged, you can only replace the entire fuel
pump assembly.
When reassembling, it is necessary to pre-tighten
diagonally and then tighten 5 bolts, otherwise the uneven
compression of the sealing rubber ring of the fuel pump will
easily lead to leakage and cause potential safety hazards.

4.Canister solenoid valve

When there is suboptimal engine performance; Poor idling;
When the air-fuel ratio is incorrect, the solenoid valve of the
carbon canister should be checked.
