FUEL SYSTEM(w/ Canister Pump Module) PRECAUTION
BEFORE WORKING ON FUEL SYSTEM
Before inspecting and repairing the fuel system, disconnect the cable from the negative (-) auxiliary battery terminal.
Note:After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notice before proceeding with work.
Do not smoke or work near fire when handling the fuel system.
Keep fuel away from rubber or leather parts.
DISCHARGE FUEL SYSTEM PRESSURE
CAUTION:The Discharge Fuel System Pressure procedures must be performed before disconnecting any part of the fuel system.
After performing the Discharge Fuel System Pressure procedures, pressure will remain in the fuel line. When disconnecting the fuel line, place a cloth or equivalent over fittings to reduce the risk of fuel spray.
Remove the console box assembly.
-
Disconnect the fuel pump connector.
Put the engine in inspection mode (maintenance mode).
Start the engine.
After the engine has stopped on its own, turn the power switch off.
Crank the engine again and make sure that the engine does not start.
Loosen the fuel tank cap, then discharge the pressure in the fuel tank completely.
Disconnect the cable from the negative (-) auxiliary battery terminal.
Note:When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
Connect the fuel pump connector.
Install the console box assembly.
FUEL SYSTEM
When disconnecting the fuel pressure fuel line, a large amount of gasoline will spill out. Follow these procedures.
Disconnect the fuel pump tube.
Drain any fuel remaining inside the fuel pump tube.
To protect the disconnected fuel pump tube from damage and contamination, cover it with a plastic bag.
Put a container under the connection.
