A. Reprogram the Powertrain Control Module
NOTE:An updated J1962 cable has been released. This cable has a red colored connector at the DRBIII(R) connection. Use this cable whenever a flash is being performed.
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. Before beginning the flash procedure, remove any old flash files from the DRBIII memory. To clear the memory from the "Main Menu":
a. 10Simultaneously press the "MORE" and "YES" keys.
b. 10A screen will appear requesting a "COLD BOOT".
c. Follow the on screen instructions by selecting the "F4" key.
d. When the DRBIII reboots to the MAIN MENU, continue with Step 2.
2. With the ignition switch in the "RUN" position, determine the original part number of the PCM currently in the vehicle. Using the DRBIII:
a. Select "DRBIII Standalone".
b. Select "1998 2007 Diagnostics".
c. Select "All (Except Below)".
d. Select "Engine".
e. Select "Module Display".
f. Record the "PCM part #" for later reference.
3. Connect the DRBIII to TechCONNECT. Open TechTOOLS and verify that the "DRBIII Status: Connected" message is in the upper right corner of the TechTOOLS screen.
4. Enter the PCM part number recorded in Step 2f in the "Parts Criteria" area and select "Show Updates". TechTOOLS will populate the appropriate flash file.
5. Select the flash file.
6. Select the "DRBIII" radio button which is next to the "Download/Update" button.
7. Select the "Download/Update" button.
8. Monitor the "Flash Download/Update Progress" window on the TechCONNECT and follow the instructions on TechCONNECT. When the flash process is complete, proceed to Step 9.
9. Disconnect the DRBIII from TechCONNECT.
10. Open the hood and install a battery charger. Using a voltmeter, verify that the charging rate provides 13.2 13.5 volts. Set the battery charger to continuous charge. Do not allow the charger to time out during the flash process.
11. Connect the DRBIII to the vehicle.
12. Download the flash file from the DRBIII to the vehicle. Using the DRBIII:
a. Select "Vehicle Flash".
b. Follow the directions on the DRBIII screen.
c. When the flash process is complete, proceed to the next step.
13. Reset the "Pinion Factor" as necessary.
14. Perform the transmission Quick learn Procedure as necessary.
15. Due to the PCM programming procedure, a Diagnostic Trouble Code (DTC) may be set in other modules within the vehicle. Some DTC's may cause the Malfunction Indicator Lamp (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.
16. Turn off the battery charger and disconnect it from the vehicle.
17. Type or print (with a ballpoint pen) the recall number, dealer code and date on an Authorized Modifications Label (Figure 1).
18. Attach the Authorized Modifications label near the VECI label.
19. For vehicles build from August 1, 2004 through September 30, 2004 (MDH 080100 through 093023) continue with Section B. Replace Fuel Pump Module. Vehicles with a build date that is not in the above date range DO NOT require a new fuel pump module.
