Functional
testing
Once the installation is
complete a test drive should
be performed to ensure that
the SmartLock Trans Brake
is functioning properly. The
following procedure should be
used to verify that the Torque
Converter is locked when
the brake is active and that
it disengages at the proper
engine speed.
1.
Obtain a vehicle speed of
45 mph in 3rd gear (engine
speed should not exceed
2200 rpm, adjust speed as
required). NOTE: This test
should be performed on a
stretch of road where it is
safe to allow the vehicle to
slow to approximately 20
mph.
2.
While maintaining 45
mph, turn the power switch
for the Banks Brake to the
“ON” position. Release the
accelerator pedal to activate
the exhaust brake.
3.
Downshift to 2nd gear.
4.
Once the exhaust brake is
activated the torque converter
will lock. Allow the vehicle
to slow until the rpm drops
below 1600 rpm.
5.
At an engine speed of
1600 rpm the SmartLock
Trans Brake will return
the control of the torque
converter to the factory
computer and it will unlock.
When the torque converter
unlocks, the engine speed
will drop rapidly and this is an
indication that the SmartLock
Trans Brake is functioning
properly.
6.
Once this functional
testing has been successfully
performed, the SmartLock
is ready for years of reliable
service.
trouble-
Shooting
If the converter does not
lock when engine speed is
above 1600 rpm, the purple
wire that was T-tapped onto
the white/pink (or brown/
orange) wire may have a
faulty connection. Verify that
the purple wire is installed
correctly and the T-tap is on
the correct wire.
If the “Service Engine Soon”
light becomes illuminated,
the wire connections at the
transmission are suspect and
their installation should be
double-checked. The “Service
Engine Soon” light will go out
when the wiring problem is
corrected. An internal code
will remain present in the
vehicle’s computer until the
code is cleared using a scan
tool or by disconnecting
the vehicle’s batteries for
approximately 20 minutes.
