B. Reprogram the CCN Using Starscan

NOTE:
The CCN is "abort - recovery" supported. If this flash process is interrupted/aborted repeat the procedure.

1. Open the hood. Install a battery charger and verify that the charging rate provides 13.2 to 13.5 volts. Do not allow the charger to time out during the flash process. Set the battery charger timer (if so equipped) to continuous charge.

NOTE:
Use an accurate stand-alone voltmeter. The battery charger voltmeter may not be sufficiently accurate. Voltages outside of the specified range will cause an unsuccessful flash. If voltage reading is too high, apply an electrical load by activating the park or headlamps and/or HVAC blower motor to lower the voltage.

2. Connect the CH9410 StarSCAN ethernet cable to the StarSCAN and the dealer's network drop.

3. Connect the CH9404D StarSCAN vehicle cable to the StarSCAN and the vehicle data link connector.

4. Place the Ignition in the "RUN" position, then Power "ON" the StarSCAN.

c. Highlight the listed calibration on the StarSCAN screen.

d. Select "Download to Scantool".

e. Select "Close" after the download is complete, then select "Back".

f. Highlight the listed calibration.

g. Select "Update Controller" and follow the on screen instructions.

h. When the update is completed, select "OK".
