CAUTION! The HCP is flash programmable and is sensitive to cold temperature during
module flashing. The HCP will need to be flashed when the vehicle is at room
temperature. Failure to flash the module at room temperature can cause the flash
procedure to not complete which could suggest an unnecessary component
replacement.
REPAIR PROCEDURE:
NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2 volts. Do
not allow the charging voltage to climb above 13.5 volts during the flash process.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.

• YES>>> Proceed to Step 2.
• NO>>> Proceed to Step 3.
2. Does the HCP control module have the latest software already installed?
• YES>>> This bulletin has been completed. Use inspect LOP (18-19-86-93) to close the
active RSU.
• NO>>> Proceed to Step 3.**
3. Reprogram the HCP with the latest software. Detailed instructions for flashing control modules
using the wiTECH Diagnostic Application are available by selecting the application’ ”HELP” tab.
4. Clear any DTCs that may have been set in other modules due to reprogramming. The wiTECH
application will automatically present all DTCs after the flash and allow them to be cleared.

• The failure code “RF” (Required Flash) can no longer be used on Technical Service Bulletin
flashes. The “RF” failure code must be used on an RSU.
