FUEL SYSTEM

PRECAUTION

1. DISCHARGE FUEL SYSTEM PRESSURE

a. Disconnect the cable from the negative (-) battery terminal.

b. Disconnect the 2 fuel pump ECU connectors.

c. Connect the cable to the negative (-) battery terminal.

d. Start the engine. After the engine has stopped on its own, turn the ignition switch OFF.

HINT:

DTC P0171/0174 (system too lean) may be set.

e. Crank the engine again, then check that the engine does not start.

f. Loosen the fuel tank cap, then discharge the pressure in the fuel tank completely.

g. Connect the 2 fuel pump ECU connectors.

CAUTION:



Before working on the fuel system, disconnect the cable from the
negative (-) battery terminal.



Do not smoke or be near an open flame when working on the fuel
system.



Keep gasoline away from rubber or leather parts.

CAUTION:



Do not disconnect any part of the fuel system until you have
discharged the fuel system pressure.



Even after discharging the fuel pressure, place a cloth or
equivalent over fittings as you separate them to reduce the risk
of fuel spray on yourself or in the engine compartment.

NOTE:



Some systems need to be initialized after the cable is
reconnected (see INITIALIZATION ).



After the ignition switch is turned OFF, the navigation system
requires approximately 90 seconds to record various types of
memory and settings. As a result, after turning the ignition
switch OFF, wait 90 seconds or more before disconnecting the
cable from the negative (-) battery terminal.
