A. Reprogram the PCM (DR, KJ PT, TJ, PL Models)

The DealerCONNECT System, DRBIII(R) (Diagnostic Readout Box scan tool), CH7000A flash cable and CH7035B data cable are required to perform this repair. Do not attempt to perform the flash procedure using an outdated CH7000/CH7001 flash cable.

NOTE:
Whenever a controller is reprogrammed, the software in the DRBIII scan tool must be programmed with the latest revision level available.

NOTE:
If the flash process is interrupted or aborted, the flash should be restarted and then follow the directions on the DRBIII scan tool.

1. Open the hood, install a battery charger and verify that the charging rate provides approximately 13.5 volts.

2. Connect the DRBIII CH7000A flash cable from the DRBIII scan tool to the data link connector located inside the vehicle under the steering column.

3. Connect the CH7035B data cable from the DealerCONNECT machine to the MDS port on the DRBIII scan tool.

4. Place the vehicle's ignition key in the "RUN" position.

5. From the DealerCONNECT "WELCOME" screen, enter your "User I.D.," "Password" and "Dealer Code".

6. From the DealerCONNECT "HOME PAGE" select the "SERVICE" tab.

7. From the "SERVICE" tab screen select "TechTOOLS".

8. If the DRBIII scan tool does not "Auto Connect" select H2 on the DRBIII key pad "Connect to TechCONNECT".

9. After the "Auto Connect" process is complete, select "READ PART NUMBER(S) FROM VEHICLE" on the TechCONNECT screen.

10. Continue following the TechCONNECT on-screen instructions.

11. Select the applicable update calibration.

12. Select the "DRBIII" button located at the bottom of the TechCONNECT monitor screen.

13. Select the "DOWNLOAD / UPDATE" button located next to the "DRBIII" button.

NOTE:
The system software Will automatically download to the DRBIII scan tool.

14. After the software download to the DRBIII scan tool is complete, close the "FLASH DOWNLOAD / UPDATE PROGRESS" window.

15. Disconnect the DRBIII scan tool from the TechCONNECT CH7035B data cable.

16. Select # 1 "RETURN TO NORMAL MODE" on the DRBIII scan tool.

17. Use the following procedure to download the flash from the DRBIII scan tool to the vehicle.

a. Select # 7 "VEHICLE FLASH" on the DRBIII scan tool.

b. Follow the directions displayed on the DRBIII scan tool screen.

c. After the reprogramming is complete, record the new module part number displayed on the DRBIII scan tool screen.

d. Press the "PAGE BACK" button on the DRBIII scan tool.

e. Follow the directions displayed on the DRBIII scan tool screen.

18. Due to the PCM flash procedure, Diagnostic Trouble Codes (DTC's) may be set in other modules (ETAX, BCM, MIC, SKIM, ABS, ORC) within the vehicle (if so equipped). Some DTC's may cause the Malfunction Indicator Light (MIL) to illuminate. All of the DTC's relate to a loss of communications with the module that is being flashed. Check all modules, record the trouble codes, and erase the trouble codes using the following procedure:

a. Turn the vehicle's ignition key to the "RUN" position

b. From the DRBIII scan tool Main Menu select # 1 "DRBIII Stand-Alone".

c. From the DRBIII scan tool Stand-Alone menu select # 3 "Vehicle Module Scan".

d. From the DRBIII scan tool Vehicle Module Scan menu select # 1 "1998 - 2005 Module Scan".

e. Select "YES" on the DRBIII scan tool key pad to scan for DTC's.

f. Follow the instructions on the DRBIII scan tool screen.

g. Once the scanning process is complete, the DRBIII scan tool will display a list of all the modules. Modules on the list that have an asterisk next to them have DTC's that need to be cleared.

h. Select the module that needs to have the DTC's cleared and follow the instructions on the DRBIII scan tool screen to clear the DTC's.

NOTE:
Erase any DTC's in the PCM only after all other modules have had their DTC's erased.

i. Turn the vehicle's ignition key to the "OFF" position.

19. Disconnect the DRBIII scan tool from the vehicle.

20. Turn off the battery charger, disconnect it from the vehicle and then continue with Section C - Install the Authorized Modifications Label.
