At this time, the conditions required to set the DTC are not present.
NOTE: Use the Freeze Frame Data to help duplicate the conditions that set
the DTC. Pay particular attention to the DTC set conditions, such as: VSS,
MAP, ECT and Load.
Note: Visually inspect the related wiring harness, look for any chafed,
pierced, pinched, or partially broken wires.
Note: Visually inspect the related wiring harness connectors. Look for
broken, bent, pushed out, or corroded terminals.
Note: Refer to any technical service bulletins that may apply.
Perform a wiggle test of the wiring harness and connectors while the engine is
running. Listen for the engine to miss or stall. Also, watch for the Good Trip Counter
to change to zero.
Were any problems found?
All
Yes
→
Repair the wiring harness/connector as necessary.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No
→
Test Complete.
