Place injector inside top of burette.
A33C5WA
Connect vehicle communication kit (VCK) and use
B.U.D.S. software. Install the tether cord cap on
the DESS post and press the engine START/RER
buttontowakeuptheECM.
Use appropriate wires and connect fuel pump di-
rectly to battery posts to continuously supply fuel
pump.
Energize the appropriate injector under Injector
Flow Measurement in Activation tab.
Energize each injector individually and measure
the gas volume injected. Quantity of gas must be
within the following specifications.
INJECTOR
VOLUME OF FUEL
mL (US oz)
Blue 16 ± 1 (.54 ± .03)
Brown 21 ± 1.5 (.71 ± .03)
If an injector is out of specification, retest it 2 - 3
times. If it still fails, replace it.
If all injectors fail, it is unlikely a failure of injec-
tors. First ensure your reading from the burette
is appropriate (pay attention to the division lines).
Ensure fuel tank is full. Test for leaks in fuel sys-
tem, fuel pump pressure, filter condition (in-line
and in tank).
Properly reinstall parts.
Electrical Test
Voltage Test
Tether cord cap must be on DESS post.
Using the vehicle communication kit (VCK) with
the B.U.D.S. software, energize the fuel injector
from the Activation section.
If the injector does not work, disconnect the plug
connector from the injector.
Install a temporary connector to the injector with
wireslongenoughtomaketheconnectionoutside
the engine compartment and apply voltage (12 V)
to this test harness.
This will validate the injector mechanical and elec-
trical operation.
If it does not work, replace it. If it works, continue
procedure.
Wake up ECM using START button and measure
voltage between terminal 1 (of injector on harness
side) and battery ground.
If 12 V is read, disconnect connector A from the
ECM and check continuity of circuit as per follow-
ing table. If it is good, try a new ECM.
