ET4 Communication Adapter3 478-0235 538-5051 317-7485 Diagnostic Tool for Caterpillar CAT Truck Excavator Scanner with 2019C 2021B 2023A Software (Only 6pin Cable)
Fcrhcy ET4:478-0235 538-5051. Our software comes with a new version of ET v2023A software. Equipped with fast USB communication. Operating systems: Windows 10. (We recommend the most stable system: win10 64-bit professional version.) || Powerful Function:Equipped with USB interface, easy to operate data analysis, fa-ult codes, time adjustment, throttle calibration, timing calibration, hydraulic flow matching, computer board maintenance, refresh, computer board programming, computer board configuration modification, EFI engine maintenance. || Cylinder breaking test, overrun test, rotary test, ET are not only diagnostic tools, but also powerful maintenance functions such as maintenance calibration: PRV main pump control pressure calibration, PRV power shift calibration, PRV hydraulic cooling fan calibration, PRV optional valve flow control calibration. || Note:The difference between the ET4 Ethernet version and the ET4 standard version is that the enhanced Ethernet cable can speed up the efficiency, save more time in detection and programming, allow the fa-ult problem to be solved quickly, and also allow the programming to reduce the time by at least 10 times. It has time value. || All-round service: If you have any questions before or after purchase, please feel free to send us an email to <877421396@qq.com>, and we will reply and answer them in time. (Regarding the software installation service, we only provide you with one free installation. Because the installation involves technical costs, if you need to install the software again for any reason, you will be charged the corresponding fee. But please rest assured that we absolutely guarantee that the software installed for free for the first time can run normally, eliminating your concerns about use)

Illustration 1 g02643856
Schematic of the Implement Pilot Supply Sensor
This diagnostic code is recorded when the ECM reads the input signal from the Implement Pilot Supply Sensor and the PWM duty cycle is above normal.The sensor is a PWM sensor that operates at a frequency of approximately 500Hz 100Hz. The sensor sends a PWM input signal to the ECM. The duty cycle of the signal will vary from 2% to 98%.The possible causes of this diagnostic code are listed below:
There is an open in the sensor circuit.
The signal circuit is shorted to another circuit.
The sensor has failed.
The ECM has failed. This condition is unlikely.Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear the diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 0434 FMI 03 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.System Response:
The events related to this sensors signal will not work properly. Test Step 1. CHECK FOR POWER AT THE SENSOR.
Do not disconnect the harness connector from the sensor.
Turn the key start switch and the disconnect switch to the ON position.
At the back of the harness connector for the sensor, insert a 7X-1710 Multimeter Probe along the voltage supply wire (contact 1).
Measure the voltage from contact 1 to frame ground.Expected Result:The voltage is between 8.0 0.4 VDC.Results:
