Diagnosis Description
Fuel Pump Relay
Enable the fuel pump relay.
ON/OFF
Note
This test can only be carried out when the
vehicle speed is equal to zero and vehicle
speed sensor has no fault.
This function can control the fuel pump relay. Fuel
pump relay will be on or off within 3-5s.
Canister Control Valve
Enable the Canister solenoid
valve.
ON/OFF
When the command is "ON" the solenoid valve will
be on or off within 3-5s.
Fan 1
Enable the Low-Speed cooling
fan.
ON/OFF
Note
Carry out this test only when the engine
coolant temperature is below 100°C
(212 ºF)and Air-Conditioning is not switched
on.
This function controls the Low-Speed cooling fan
relay. When the instruction is received, the cooling
fan will be on at high speed for 5s.
Fan 2
Enable High-Speed cooling fan
ON/OFF
Note
Carry out this test only when the engine
coolant temperature is below 100°C
(212 ºF)and Air-Conditioning is not switched
on.
This function controls the High-Speed cooling fan
relay. When the instruction is received, the cooling
fan will be on at high speed for 5s.
Air-Conditioning Clutch
Enable the Air-Conditioning
compressor clutch.
ON/OFF
Note
Carry out this test only when the ignition
switch is at "ON" position and the engine is
not running.
This function controls Air-Conditioning
compressor relay. When the instruction is "ON",
the Air-Conditioning compressor relay will be on
or off in 3-5s.
Fuel Injection Disable
Disable the fuel injection.
ON/OFF
Note
This function will not close the two fuel
injectors at the same time. perform the test
only when the vehicle speed is zero, the
speed sensor without fault and oxygen
sensor signal indicating a lean Air-Fuel ratio.
Disable fuel injectors and test fuel injectors sealing
state.
