Troubleshooting Test Steps Values Results
1. Check for Codes
A. Turn the DC breaker, located in the power distribution box, to the ON position.
B. Connect Cat® Electronic Technician (ET) to the service tool connector.
C. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: A code is active or logged.
Proceed to Test Step 2.
2. Check the Air Supply to the Dosing Cabinet
A. Turn the DC breaker, located in the power distribution box, to the OFF position.
B. Disconnect the air supply line to the dosing cabinet.
C. Install a pressure gauge on the air supply line to the dosing cabinet.
D. Monitor the air supply pressure from the air compressor.
E. Reconnect the air supply line to the dosing cabinet.
483 kPa to 1068 kPa (70 psi to 155 psi)
Result: The air supply pressure from the air compressor is 483 kPa to 1068 kPa (70 psi to 155 psi).
Proceed to Test Step 4.
Result: The air supply pressure from the air compressor is greater than 1068 kPa (155 psi).
Repair: There is a problem with the air supply to the dosing cabinet. For information on the air compressor, refer to the Original Equipment Manufacturers (OEM) service information.
If the problem is not resolved, proceed to Test Step 3.
3. Check the Air Pressure
A. Turn the DC breaker, located in the power distribution box, to the ON position.
