Proceed to Test Step 3.
Result: The electronic service tool snapshot was not successfully saved.
Contact the DSN for guidance.
3. Turbocharger Wastegate (C4.4 TA and C7.1 only)
Note (C7.1): On engines with a single turbocharger, the wastegate is attached to the turbocharger. On engines with twin turbochargers, the wastegate is attached to the high-pressure turbocharger.
Note (C4.4): On engines with a single turbocharger, the wastegate is attached to the turbocharger. Engines with twin turbochargers have an electronic wastegate (refer to Step 5).
A. Check the pipe assembly from the air inlet elbow to the turbocharger wastegate for cracks or damage. Ensure that the hose clamps are secure and not damaged.
B. Check the operation of the wastegate on the turbocharger.
C. Check the operation of the wastegate actuator on the turbocharger. Refer to Systems Operation, Testing, and Adjusting, "Turbocharger - Inspect". For C7.1 engines, refer also to Special Instruction, M0084071, "Turbocharger Wastegate Actuator on Certain C7.1 Engines".
Turbocharger wastegate
Result: The pipe assembly or hose from the air inlet elbow to the turbocharger wastegate is cracked or damaged. The hose clamps are not secure.
Repair: Replace any damaged components.
Result: Operation of the turbocharger wastegate is suspect.
Repair: Disconnect the output rod in the wastegate actuator from the lever that operates the wastegate.
Operate the wastegate lever by hand and check for full and free movement.
Check that the output rod in the wastegate actuator is biased towards the retracted position.
Connect the output rod in the wastegate actuator to the lever that operates the wastegate.
If the wastegate is not operating correctly, replace the turbocharger. Refer to Disassembly and Assembly, "Turbocharger - Remove" and Disassembly and Assembly, "Turbocharger - Install".
Result: There is a suspected fault in the wastegate or the wastegate actuator.
Repair: Replace the turbocharger. Refer to Disassembly and Assembly, "Turbocharger - Remove" and Disassembly and Assembly, "Turbocharger - Install".
Result: The wastegate and the wastegate actuator operate correctly.
Proceed to Test Step 4.
4. Wastegate Regulator
A. Use the electronic service tool to check for diagnostic trouble codes that relate to the wastegate regulator.
Wastegate regulator
Result: Diagnostic codes are present that relate to the wastegate regulator.
Repair: Rectify the cause of any related codes. Refer to Troubleshooting, "Diagnostic Trouble Codes".
Result: There are no diagnostic codes that relate to the wastegate regulator.
If the fault is still present, contact the DSN and provide the following information from Test Step 1 and Test Step 2:
• Warranty Report
• PSR and Histograms
• Snapshot data
5. Turbocharger Electronic Wastegate Regulator (C4.4 TTA only)
A. Use the electronic service tool to perform the "Air System Motor Valves Verification Test" to check that the turbocharger wastegate is operating correctly.
B. Inspect the turbocharger. Refer to Systems Operation, Testing and Adjusting, "Turbocharger - Inspect".
Turbocharger wastegate
Result: Diagnostic codes became active during the "Air System Motor Valves Verification Test"
Repair: Troubleshoot the diagnostic codes. Refer to Troubleshooting, Diagnostic Trouble Codes.
If the wastegate is not operating correctly, disconnect the linkage from the actuator by removing the circlips. Check the crank on the turbine housing for free movement. If the crank moves freely, replace the wastegate actuator.
Use the electronic service tool to perform the "Air System Motor Valve Verification Test" to verify that the repair eliminates the fault.
If the crank does not move freely, replace the turbocharger assembly. Refer to Disassembly and Assembly , Turbocharger - Remove and Disassembly and Assembly , Turbocharger - Install.
If a turbocharger equipped with an electronic wastegate is replaced, use the electronic service tool to perform the "Turbocharger Wastegate Actuator Replacement Reset".
Use the electronic service tool to perform the "Air System Motor Valve Verification Test"
Result: There is a suspected fault in the wastegate or the wastegate actuator.
Repair: Replace the turbocharger. Refer to Disassembly and Assembly, "Turbocharger - Remove" and Disassembly and Assembly, "Turbocharger - Install".
If a turbocharger equipped with an electronic wastegate is replaced, use the electronic service tool to perform the "Turbocharger Wastegate Actuator Replacement Reset".
