SCHlabs - Multi car sensor and actuator tester

The HMP1 is the most complete tool for mechanics testing, reading and/or emulating almost all car sensors.
It is so complete that it becomes the essential tool for servicing internal combustion vehicles.

Among its functions, we can highlight its ability to read and generate CKP & double CMP pulses simultaneously and the complete test of motorized throttle bodies and many more functions.

There are 3 types of possible actions for each sensor.
[T] Test. It means that the HMP1 can check the operation with the sensor/actuator outside the car (or disconnected)
[R] Reading. It means that you can read the operation without disconnecting it from the car and read/monitor its operation that way.
[E] Emulate. It means that the HMP will act as if it were the sensor so that the injection “believes” that the sensor is in place and working.

The HMP1 can generate analog voltages to simulate analog sensors.
The test can be with a manually generated voltage or use one of the 5 curves built into the HMP1.
The voltage comes out through the TPS2 pin and is injected by disconnecting the true sensor.

The purpose of these tests is to inject the voltage and monitor the ECU's response and reading of the input voltage / signal.
This verifies both the wiring and the ability of the ECU to read the signal.

After selecting GEN An from the main menu, you must choose one of the 6 different operating modes listed below and the screen will look like this:

A) Is generating voltage
B) Generated voltage
C) Work mode

Manual:
A continuous voltage is generated between 0 and 5v. With the + and - keys you raise or lower the voltage.

Lambda:
A voltage is generated that oscillates between 0.2 and 0.8v continuously.
With the + and - keys change the cycling speed.

TPS (Throttle Position Sensor):
A voltage that oscillates between 0.8 and 4.7v is generated as if the butterfly were opening and closing continuously over and over again.

With the + and - keys change the cycling speed.

MAP (Manifold Air Pressure):
A signal is generated as if doing a full throttle.

1)When the test starts it emits a voltage as if the motor was stopped.
2) Pressing + outputs a voltage as if the engine was idling.
3) ressing + again generates a signal as if you had made a sudden acceleration.
At the end of the accelerated cycle, the signal returns to idle.

MAF (Mass Air Flow):
A signal is generated as if doing a full throttle.

MAFd (Mass Air Flow in Diesel):
A signal is generated as if doing a full throttle.
