The kit consists of COMMON RAIL tester TCR-4 and COMMON RAIL injector tester ICR-4.
COMMON RAIL tester TCR-4
TCR-4 tester is intended to diagnose the Common Rail injection systems. It is used to read values from the high pressure sensor and to control two control pressure valves at a time.
It can be used both to read the pressure and to control the control valves in a car as well as to diagnose the high-pressure pumps on the table. It is necessary to monitor the pressure in the container, thanks to which it is possible to assess adequately the state of the high pressure pump.
This tester can also be used to monitor the fuel pressure in the FSI-type injection systems.

Function of the Tester TCR-4:
This function allows you to enter the maximum working pressure (Pmax) of the high-pressure sensor, which is used in a tested car.
After selecting this function, check the continuity of the following circuits:
- High pressure sensor circuit
- Circuit of the valve 1
- Circuit of the valve 2
In order to test the continuity of each circuit, the tester is able to give an answer if the circuit correctly responds to a specific test signal.
In case of the test of the high pressure sensor circuit, the result does not give the absolute certainty about its error-free operation throughout the range of working pressures up to the pressure Pmax. Complete confidence can be obtained by observing the reading of the pressure sensor during the engine operation.
3.1. High Pressure Reading
Current pressure is read by the sensor of high pressure.
3.2. Additional functions
3.3. Changing the control valve 1
The change of the signal is performed with a control potentiometer. The accuracy of the changes can be adjusted by pressing the appropriate button.
3.4. Changing the control valve 2
The change of the signal is performed using a control potentiometer. The accuracy of the changes can be adjusted by pressing the appropriate button.
COMMON RAIL injector tester ICR-4
Supply voltage | DC 12 ... 15V |
Current draw | up to 4A (fuse) |
Number of controlled injector | |
electromagnetic | 4 |
piezoelectric | 4 |
Parameters of the simulated injection | |
frequency | 36 ... 4800 /m (change in steps of 10 /m) or 0.3 ... 40Hz (for every injector) |
pulse | 100 ... 5000 mks (change in steps of 10 mks) |
Programming the number of rpm | yes |
The option of the initial injection | yes (at frequences 36 - 2400 /m or 0.3 - 20 Hz) |
After you start the injectors, the tester performs a sequence of injections in the quantity indicated by the parameter "Quantity".
Change of the value of the simulated engine speed
The parameter "Speed" indicates the simulated value of rpm. This value is the real value of the car's engine speed, so that the injector injects half as many times. The range of changes of this parameter ranges from 30 rpm to 2500 rpm.
Change of the value of the simulated injection time
The parameter "time" defines the time of injection of the injector. This parameter change ranges from 0.1ms to 5.0 ms. Changes can be performed every 0.1 ms or every 1ms.
Programming the number of sequences
The "Number" parameter specifies the number of injection sequences to be performed. A sequence of injections is meant to be four injections, one for each injector. The tester always performs the total number of the injection sequences. This parameter change ranges from 0 to 9999. Changes can be performed every 10 or every 100.
The tester performs the set number of sequences and indicates the number of the sequence, which is being currently performed on the display. After the performance of the set number of sequences, the tester stops its operation.
Simulation of the initial injection
The "initial" parameter enables the simulation of the initial injection. If the parameter has the "yes" value, the pre-injection will be performed before each injection. The pre-injection parameters are fixed at:
