Troubleshooting Test Steps Values Results
9. Check the Crankshaft Timing Ring and the Camshaft
Position Wheel
A. Inspect the crankshaft timing ring. Refer to Disassembly
and Assembly, “Crankshaft Timing Ring - Remove and Install”.
B. Inspect the camshaft position wheel. Refer to Disassembly
and Assembly, “Camshaft Gear - Remove and Install”.
Defects Result: Found fault with the crankshaft timing ring or the cam-
shaft position wheel
If necessary, replace the camshaft position wheel. Refer to Dis-
assembly and Assembly, “Camshaft Gear - Remove and
Install”.
If necessary, replace the crankshaft timing ring. Refer to Disas-
sembly and Assembly, “Crankshaft Timing Ring - Remove and
Install”.
Use the electronic service tool in order to clear all logged diag-
nostic codes and then verify that the repair has eliminated the
fault.
Result: No faults found.
Contact the Dealer Solution Network (DSN).
10. Check if a Replacement ECM Eliminates the Fault
A. Contact the DSN.
B. If the DSN recommends the use of a replacement ECM, in-
stall a replacement ECM. Refer to Troubleshooting, “Replac-
ing the ECM”.
C. Use the electronic service tool to recheck the system for ac-
tive diagnostic codes.
Diagnostic
codes
Result: There are no active diagnostic codes with the replace-
ment ECM.
Reconnect the suspect ECM. If the fault returns with the sus-
pect ECM, replace the ECM.
Use the electronic service tool in order to clear all logged diag-
nostic codes and then verify that the repair eliminates the fault.
Result: The diagnostic code is still present with the replace-
ment ECM.
Contact the DSN.
