NOTE:
Verify that the PCM is at the latest software level (flash level). If necessary, update the PCM in accordance with the Service Information.
1. With the scan tool, read DTCs and Freeze Frame Data and record on the repair order.
2. With the scan tool, erase DTCs.
3. Using the recorded Freeze Frame Data and the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
4. With the scan tool, read DTCs.
