11. Using the DRB III scan tool, program the new PCM with the vehicle's Vehicle Identification Number (VIN) and current vehicle mileage.
NOTE:
Failure to reprogram the new PCM with VIN information and mileage may cause a Diagnostic Trouble Code (DTC) to be set.
a. Connect the DRB III to the underdash diagnostic connector.
b. Select "DRB III STANDALONE" (1) and then press "Enter".
c. Select "1998 - 2001 DIAGNOSTICS" (1) and then press "Enter".

h. Follow the instructions on the DRB III screen to enter the VIN.
CAUTION:
Verify that the correct VIN is displayed on the DRB III before pressing the "Enter" key. The VIN cannot be changed once it is entered. If an incorrect VIN is entered, the module must be replaced to correct the VIN error.
i. Press the "PAGE BACK" button on the DRB III key pad.
j. Select "SRI MEMORY CHECK" (3) and then press "Enter".
k. Follow the instructions on the DRB III to enter the current vehicle mileage.

C. Check for PCM Software Updates:
NOTE:
The MDS2 (Mopar Diagnostic System) with the DRB III (Diagnostic Readout Box scan tool) operating at the latest release is required to perform this repair.
1. Log onto the MDS2 system.
2. Connect the MDS2 (Mopar Diagnostic System) and DRB III (Scan Tool) to the vehicle and switch the IGNITION KEY TO "ON"
3. Use the arrow keys and select # 2 CONNECT TO MDS2 on the DRB III MAIN MENU SCREEN.
4. Use the arrow keys and select # 2 RUN MDS2 APPLICATION on the DRB III MAIN MENU SCREEN.
NOTE:
Once MDS2, DRB III and vehicle communication have been established, the CANNOT READ VIN FROM DRB III message will be replaced by the VEHICLE VIN. Press the "OK" button to request an MDS2 SESSION FOR THE VEHICLE VIN INDICATED. Press the "OK" button when asked to begin the session.
5. Push the FLASH TAB on the MDS2.
6. Select READ PART NUMBERS FROM VEHICLE and click SHOW UPDATES on the MDS2. Press the "OK" button.
NOTE:
If the PCM on the vehicle has already been updated or reprogrammed, a Flash Update Information Box will appear that says "Part number (updated part number is displayed) is up to date and does not require any new updates." Verify that the part number of the PCM (or previously installed authorized software update label) matches the part number displayed on the MDS. Press the "OK" button; then continue with Step E.
7. Select the NEW SOFTWARE PART NUMBER with the light pen and click UPDATE CONTROLLER SOFTWARE.
8. The MDS2 and DRB III will prompt for any operator action needed during the remainder of the reprogramming process.
NOTE:
Due to the PCM flash procedure, diagnostic trouble codes (DTC's) may be set in other modules (ETAX, BCM, MIC, SKIM, ABS) 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 prior to returning the vehicle to the customer. Erase any trouble codes in the PCM only after-all other modules have had their trouble codes erased.
9. Continue with Section D - Install Authorized Software Update Label.
D. Install Authorized Software Update Label:
Type or print (with a ballpoint pen) the part number, dealer code and date on the Authorized Software Update Label, and attach it to the PCM. Cover the label with the clear plastic portion of the label. Continue with Section E - Install the Authorized Modifications Label.
