NOTICE:
·

As SST (tie band) does not completely prevent SST (clamp) from becoming loose, do not subject the parts to any impacts while using them.

·

Before using SST (tie band), make sure that there is no wear, damage or cracks. If there are any abnormalities, replace SST (tie band).



HINT:

When removing SST (tie band), disengage the lock.



viii.

Check that SST (clamp) and SST (adapter) cannot be easily separated.


ix.

Set the port fuel injector assembly into a graduated cylinder.


x.

Connect the GTS to the DLC3.


xi.

Turn the power switch on (IG).

NOTICE:

Do not start the engine.



xii.

Turn the GTS on.

*a SST (EFI Inspection Wire K)


Connect SST (EFI inspection wire K) to the port fuel injector assembly and auxiliary battery for 15 seconds, and measure the injection volume with the graduated cylinder. Test each port fuel injector assembly 2 or 3 times.

SST

Standard Injection Volume:
Auxiliary Battery Connection Condition Specified Condition
Positive (+) auxiliary battery terminal - Negative (-) auxiliary battery terminal Per 15 seconds 67 to 81 cc (4.1 to 4.9 cu.in.)


Difference between Each Port Fuel Injector Assembly:

14 cc (0.9 cu.in.) or less


NOTICE:
·

Make sure that SST (EFI inspection wire K) is securely connected.

·

Always switch the voltage on and off at the auxiliary battery side, not the port fuel injector assembly side.



If the result is not as specified, replace the port fuel injector assembly.



c.

Check for leaks.

i.

Disconnect SST (EFI inspection wire K) from the auxiliary battery and check for fuel leaks from the port fuel injector assembly.

Standard Fuel Drop:

1 drop or less per 20 minutes


If the result is not as specified, replace the port fuel injector assembly.


ii.

Connect the fuel tube sub-assembly.
