10. Open the hood, install a battery charger and verify that charging rate provides approximately 13.5 volts.
11. Connect the DRBIII(R) to the vehicle.
12. Download the flash from the DRBIII(R) to the vehicle. Using the DRBIII(R) select:
a. "Vehicle Flash"
b. Follow the directions on the DRBIII(R) screen. When the flash process is complete, proceed to Step # 14.
NOTE:
Due to the PCM programming procedure, a DTC may be set in other modules (TCM, BCM, MIC, SKIM, etc.) within the vehicle, if so equipped. Some DTC's may cause the MIL to illuminate. Check all modules using "Module Scan", record the DTC's, and erase these DTC's prior to returning the vehicle to the customer. Erase any DTC's in the PCM only after all other modules have had their DTC's erased.
NOTE:
The following step is required by law.
13. With the DRBIII(R) perform the TCM Quicklearn procedure.
