Connecting power supply
The dev ce need for work 12Vdc cont nuous. Become w th 2
cocodr les to allow connect to car battery.
DO NOT USE battery chargers w thout a car battery.
Connecting terminal block
Once you choose the appropr ate cable you must plug n the
rear connector.
Use
-Preassembled cables for Throttle body's and Pedals
-S ngle cable on TPS2 for analog voltage generat on
-S ngle cable on TPS1 for other measurement
Selecting test type
When you plug the power supply (12v) you w ll see the
pr nc pal menu on screen.
Us ng The keys “+” and “-” you
w ll see d fferent tests.
When you see nto the screen the
r ght test, press OK.

Testing of electronic throttle
1) THE ENGINE MUST BE STOPPED. The eng ne can be
damaged f s over accelerated mov ng the butterfly manually.
2) Choose the appropr ate cable, check the connect ons,
spec ally the co l connect on n the cable A & cable B.
3) Plug 12Vdc and throttle body and choose “throttle” on the
menu, then press ”OK”.
Into the screen you w ll see 4 nformat ons s m lar to the mage:
A=Max D fference
B=Motor Co l current
C=TPS1 pos t on ( n %)
D=TPS2 pos t on ( n %)
4) Us ng “+” and “-” move the butterfly from m n to max
open ng. If you press both the butterfly w ll move alone.
The HMP1 w ll check the cons stency between TPS1 & TPS2
and w ll show the d fference between deal measure and real
measure. Th s s the most mportant data that ECU look.
The max d fference tolerated by the ECU s d fferent
form car to car but generally s acceptable a value under 5%.

Electronic Pedal test
Connect the pedal us ng the r ght connector or use the
crocod les to connect follow ng mage.
After that you must press “+” and “-” keys unt l you see
PEDAL on screen, and press “OK”.
Now on the screen you w ll see 4 nformat ons l ke the bellow
mage:

B=D fference between C y D
C=TPS1 pos t on ( n %)
D=TPS2 pos t on ( n %)
To test t, allways w th the eng ne off, press slowly up to reach
full press. Avo d fast movements.
The HMP1 w ll calculated the coherence between TPS1 and
TPS2 and w ll shot the d fference between deal relat onsh p
and real relat onsh p.
Press ng the OK Button, you w ll come back to the pr nc pal
menu to perform another test.

In the future you w ll add new connectors. So
you w ll need know about dev ce connect ons
look ng the mage.
Report on screen
After each test, the dev e has collected all nformat on to show a
report. Use + and – to change parameter showed and OK when all s
done.
TYPE: Formula used to the throttle or pedal tested.
TPS1: ntegr ty report of TPS1 w th follow ng data, 3 data are shown:
M n mum Value, Max mum value, and track ntegr ty.
A=TPS1
C=Track cont nu ty
B=M n mum readed
D=Max mum readed
TPS2: same as TPS1.
Diffmax: The TPS1 y el TPS2 have a relat onsh p (d fferent accord ng
the car). The D ffmax s the max mum error between deal relat on of
TPS1 & TPS2 and measured values n both sensors. Normally th s
values are below 3%.
Imax: Is the max current used to move the motor. Th s parameter
allow d scard short c rcu ts and body overheat ng.
Rtps: Consumpt on ( n mA) of sensors.
Result: Is the analys s result and w ll show: GOOD, f the d ff max s
lower to 4%. REGULAR, f the d ff s between 5 y 6%. BAD f the
d fference s nadcuated and can cause troubles.

Determining common fails
-The coil have consumption, but the butterfly i n't move.
Exhausted gears.
-The ifference between TPS1&TPS2 is more than 5%.
TPS d rty or exhausted.
-The movement is not smooth.
Suc edad, o engranaje dañado
-The throttle bo y is ok, but the car have
i le problems.
D rty n the clos ng po nt, normally dust s
accumulated between the butterfly and the
ventur . Clean w th d rty cloth.
Most common trouble solutions
The evice oes not power up.
- Ver fy the r ght connect on to 12V.
The butterfly close an the screen show ”Short Error”.
-A short c rcu t s detected. The system w ll stay freezed unt l you push
OK button.
The butterfly close an the screen show ”Fuse Error”.
-The nternal fuse s opened due co l consumpt on excess. Wa t few
m nutes and press OK button. The fuse s automat cally restored.
The HMP1 show UNKNOW type.
-TPS1 & TPS2 are bad connected
-TPS1 or TPS2 s damaged.
14/16

-Throttle works but have a relat onsh p d fferent than: T1+T2=100, x2,
and Toyota.
Short circuit protection
The dev ce have an over consumpt on protect on that abort the
test and show on screen unt l you press the “OK” button.
The dev ce can be damaged n short c rcu ts, and th s
damages w ll vo d the warranty.
General Warnings
-Do not wet the dev ce, do not use chem cals to clean. Only a sl ghtly damp
cloth.

alcohol, etc etc etc)
-Do not connect the dev ce to any voltage d fferent to 12V.
-Do not plug more than one throttle body at once.
-Do not connect more than 5V w thout a prev ous select on of a test that
support t.
