NOTICE:
Under ACTIVE TEST mode, fuel pressure increases. Take precautions to prevent fuel from spraying
on you or inside the engine compartment.
HINT:
During ACTIVE TEST mode, engine speed goes high and combustion noise bec\
omes loud.
(a) Check that there are no fuel leaks from any part of the fuel system at t\
he engine stops.
HINT:
If fuel leakage could be found on specific parts, replace them with new \
parts.
(b) While cranking or when starting the engine, check that there is no leaks from\
any part of the fuel sys-
tem.
HINT:
If fuel leakage could be found on specific parts, replace them with new pa\
rts.
(c) Disconnect the fuel hose from the common rail.
(d) While cranking the engine, check fuel leaks from the return pipe.
HINT:
If there is fuel leakage, replace the common rail.
(e) Connect the hand±held tester to the DLC3.
(f) Start the engine and push the hand±held tester main switch ON.
(g) Select the FUEL LEAK test of ACTIVE TEST mode on the hand±held tester\
.
(h) If you do not have the hand±held tester, depress the accelerator pedal quickly and fully to increase the engine speed at maximum and keep it for 2 seconds. Repeat this opera\
tion several times.
(i) Check that there are no leaks from any part of the fuel system.
NOTICE:
If the leakage from the return pipe is less than 10 cc (0.6 cu in.) in\
a minute, it is acceptable.
HINT:
If fuel leakage could be found on specific parts, replace them with new \
parts.
(j) Reconnect the fuel hose to the common rail.
