Tie SST (clamp) and SST (adapter) together with SST (tie band) as shown in the illustration.

SST
09268-31015  (09268-41800)

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.



vi.

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


vii.

Set the fuel injector assembly in a graduated cylinder.


viii.

Connect the GTS to the DLC3.


ix.

Turn the power switch on (IG).

NOTICE:

Do not start the engine.



x.

Turn the GTS on.


xi.

Enter the following menus: Powertrain / Engine / Active Test / Activate the Circuit Relay.

*a SST (EFI Inspection Wire H)


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

SST
09842-30080  

Standard Injection Volume:
Auxiliary Battery Connection Condition Specified Condition
Positive (+) auxiliary battery terminal - Negative (-) auxiliary battery terminal Per 15 seconds 60 to 73 cc (3.7 to 4.5 cu. in.)


Difference between Each Fuel Injector Assembly:

13 cc (0.8 cu. in.) or less


NOTICE:
·

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

·

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



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



c.

Check for leaks.

i.

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

Standard Fuel Drop:

1 drop or less per 20 minutes


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