Aftertreatment #1 DEF Tank #2 Level : Low - moderate severity (2) E955 (2)
Low Aftertreatment #1 DEF Tank #2 Level The ECM detects that the DEF buffer tank level is below a threshold.
The code is logged.
4367-31
Aftertreatment #1 DEF Tank #2 Level E1589 (2)
Low Aftertreatment #1 DEF Tank #2 Level The ECM detects that the DEF buffer tank level is not refilling as fast as expected.
The code is logged.
If the 4367-31 code is active, the fill solenoid will be disabled until cleared.

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. 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: An E955, E1589, 4367-1, 4367–7, 4367-17, 4367-18, or 4367-31 code is active.
Proceed to Test Step 4.
Result: An E951 (1) or 1761-17 code is active.
Proceed to Test Step 2.
2. Check the Remote Diesel Exhaust Fluid (DEF) Tank Level
A. Visually inspect the level of DEF in the Remote DEF tank.
DEF Level
Result: The remote DEF Tank level is not below the low DEF level switch.
Proceed to Test Step 3.
Result: The remote DEF tank level is below the low DEF level switch.
Repair: Add DEF to the remote DEF tank.
If the problem is not resolved, proceed to Test Step 3.
3. Check for Codes
A. Turn the DC breaker, located in the power distribution box, to the ON position.
B. Connect Cat ET.
C. Determine if a code is active or logged.
Codes
Result: An E951 (1) or 1761-17 code is logged.
Return to service.
Result: An E951 (1) or 1761-17 code is active.
Repair: There is a short to ground in the wiring harness between the remote DEF tank level switch and the Selective Catalyst Reduction (SCR) controller. Repair or replace the wiring harness.
Verify that the repair eliminated the problem.
4. Inspect the Remote Tank and Supply Lines
A. Turn the DC breaker, located in the power distribution box, to the OFF position.
B. Visually inspect the remote tank and all the DEF lines between the remote tank and buffer tank.
C. Inspect the lines to ensure that the lines are connected and routed properly.
DEF Lines
Result: The DEF supply line form the remote tank to the buffer tank are connected and routed properly.
Proceed to Test Step 5.
Result: The DEF supply lines from the remote tank to the buffer tank are not connected or routed properly.
Repair: Repair or replace the damaged DEF line.
If the problem is not resolved, proceed to Test Step 5.
5. Perform a "DEF Tank Refill Solenoid Override"
A. Turn the DC breaker, located in the power distribution box, to the ON position.
B. Connect Cat ET.
C. Use Cat ET to perform the following override:
- "DEF Tank Refill Solenoid Override"
D. Use Cat ET to monitor the following:
- "DEF Tank #2 Level"
Note: After the "DEF Tank #2 Level" reaches 90 percent, the override will automatically turn off.
DEF Level
Result: The "DEF Tank #2 Level" did not increase.
Proceed to Test Step 6.
Result: The "DEF Tank #2 Level" increased.
Verify that the repair eliminated the problem.
6. Replace the DEF Filter and clean the DEF filter screen.
Refer Illustration 2 to locate the filter and filter screen.
A. Replace the DEF filter between the remote tank and the dosing cabinet.
B. Clean or replace the DEF filter screen (6) at the DEF inlet of the dosing cabinet. If the DEF filter screen is damaged, replace the filter screen. Refer to Operation and Maintenance Manual,
