ET Screen For The ARC System Test
Initiate the Cat ET.
Select the "Brake ECM".
Select "Service" from the drop-down menu.
Click on the "Start" button in order to begin the test.
The supply valve opens and the control valve gradually allows full brake system air to flow during the test. Then, the control valve will gradually stop the flow of brake system air and the supply valve will close. The cycle is then repeated. The ARC will gradually increase the pressure of the brake system to full pressure. The ARC will then decrease the pressure of the brake system to zero.
The test of the automatic retarder will terminate if a fault is detected during the test.
Follow the instructions that are being displayed on the ET screen in order to complete this procedure.
