Troubleshooting Test Steps Values Results
1. Check for Associated Diagnostic Trouble Codes
A. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
B. Determine if an associated diagnostic code is present.
Diagnostic Trouble Codes
Result: An associated diagnostic trouble code is not present.
Proceed to Test Step 2.
Result: An associated diagnostic trouble code is present.
Repair: Troubleshoot the associated code.
2. Check the Coolant Level of the Engine
A. Determine if the engine coolant level is full.
Coolant Level
Result: The coolant level is full.
Proceed to Test Step 3.
Result:The coolant level is not full.
Repair: Add coolant to the system.
Determine the cause of low coolant. Refer to Troubleshooting, "Coolant Level Is Low" for additional information.
Proceed to Test Step 3.
3. Check for Coolant Leaks
A. Check the entire engine cooling system for signs of coolant leaks.
B. Inspect the coolant supply and return lines to the Pump Electronic Tank Unit (PETU) for leaks or damage that may cause restrictions.
Leaks
Result: No leaks were detected.
Proceed to Test Step 4.
Result: There were leaks or damaged lines detected.
Repair: Repair the leaks or damaged lines and refill the coolant system.
Proceed to Test Step 4.
4. Check the Electrical Connection at the DEF Tank Header
A. Inspect the electrical connections to the DEF tank header. Refer to Troubleshooting, "Electrical Connectors - Inspect" for further information.
Look for corrosion or loose wires.
Electrical Connections
Result: The electrical connectors are free of corrosion and are not loose.
Proceed to Test Step 5.
