Injector and IAC valves tester

The car engine of injection between years 1990 and 2008 have a valve to control the idle speed. This valve is called IAC (Idle Air Control) or commonly called stepper motor.
This valve is a common fail cause.

The car engine of indirect injection have coil based injectors, they split in two big groups: High and Low impedance.
This device can test almost all IAC valves and Stepper of car industry, both groups of injectors.

Is the tool more easy to use of the market.

Manufactured for hard work, with a high endurance.
The device test multiple IAC types ( Steppers, PWM, Continous current etc)
Is a elemental tool for any modern mechanic and avanced users.

3 ways PWM IAC type testing

Test a PWM IAC valve of 3 ways is very easy.

1)Connect the HRR2 and wait for blinking lights.
2)Plug the valve and wait one seccond.
3)READY ! so easy the led 3W is turned on.

4)The buttons of right and left open and close the motor.
5)If press both side buttons at same time will start an automatic opening and close cycle.

This valve type have a displacement proportional applied over one of both coils. The other coil have a continous PWM
