Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat ET.
B. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Repair: Troubleshoot the associated code before continuing with this test.
Result: All the following codes are active:
- 3362 or E114
- 7458 or E1663
Proceed to Test Step 2.
Result: One of the following codes is active:
- 3362 or E114
- 7458 or E1663
Proceed to Test Step 6.
2. Operate the Engine
A. Start the engine.
B. Run the engine until normal operating temperature is reached.
C. Connect Cat ET.
D. Use Cat ET to monitor the following:
- Aftertreatment SCR System State
Note: The Aftertreatment SCR System State is on the Aftertreatment status screen on the Selective Catalyst Reduction System ECM.
E. Check for codes when the "Aftertreatment SCR System State" reads "Normal Dosing Operation".
Codes
Result: A code is not active.
Proceed to Test Step 3.

E. Check the operation of the "Wait to Disconnect Lamp" when the "Aftertreatment SCR System State" reads "Normal Dosing Operation".
Lamp
Result: The "Wait to Disconnect Lamp" is illuminated while the "Aftertreatment SCR System State" reads "Normal Dosing Operation".
Return to service.
Result: The "Wait to Disconnect Lamp" is not illuminated while the "Aftertreatment SCR System State" reads "Normal Dosing Operation".
Repair: Replace the "Wait to Disconnect Lamp" bulb.
If the problem is not resolved, proceed to Test Step 4.
