The Drag Torque Test is available on:
✓ Bendix EC-60 Premium or Advanced braking systems
✓ Bendix EC-80 ATC or ESP braking systems
This test raises and lowers torque limits and tests how the engine responds.
Process：
Step 1: Test Selection
To initiate the Drag Torque Test, begin by selecting the test option from the JPRO Diagnostics menu. This test is specifically applicable to Bendix EC-60 Premium or Advanced braking systems, as well as Bendix EC-80 ATC or ESP braking systems.
Step 2: Test Dialog Display
Once the Drag Torque Test is selected, a test dialog will be displayed on the JPRO interface. This dialog provides technicians with essential information and options to proceed with the test.
Step 3: Initiating the Test
To start the test, press the “Start” button on the JPRO interface. As the test progresses, the Test Status section will display the commands being sent to the engine. Technicians can observe changes in engine speed, torque values, and even engine sound. For a visual representation of the monitored data values, technicians can click on the “Graph” tab at any time during the test.
tep 4: Stopping the Test
If required, the test can be stopped at any point by selecting the “Stop” button on the JPRO interface. However, it’s important to note that the test will automatically stop after completing an increase and decrease cycle twice. When the test concludes, the braking system will reset, which can be audibly observed through clicking sounds from the brake modulator valves.
Step 5: Test Completion and Exit
Once the test is completed or if it needs to be stopped prematurely, press the “Exit” button on the JPRO interface. This will return you to the test selection dialog, allowing you to proceed with other diagnostic procedures if necessary.
Conclusion:
The Bendix EC-60 EC-80 Drag Torque Test, made possible by JPRO Diagnostics, is an essential tool for assessing the performance of braking systems in commercial vehicles. By effectively raising and lowering torque limits and observing how the engine responds, technicians can identify any potential issues with the braking system. Performing this test regularly ensures optimal braking system functionality, contributing to enhanced safety and performance on the road.
