On-Board Powertrain Control Module Replacement
1. Verify that the service stall system (SSS) version number, shown on the Main Menu screen in the upper left corner is, S26.00, or greater. If not, the SSS must be updated to version S26.00, or greater. (Call 1(800) 7SATURN for assistance.)2. Connect the vehicle to the SSS using the PDT and turn ignition switch On.
3. Select Identify Vehicle.
4. Select Read VIN from the PCM.
5 Select System Utilities.
6. Select EEPROM Reprogramming
7. Select Replace Controller.
8. Select PCM, and follow the instructions displayed until the Replace PCM screen appears on the SSS. At this time, turn the ignition Off and proceed to the next step.
IMPORTANT:
The procedure in step 8 retrieves the stored option, VIN, tire size/rating and TC adaptive information from the controller being replaced. It is very important to load the same information, especially TC adaptives, back into the new controller to prevent changing the adaptives and affecting the operation of the vehicle until it relearns.
9. To remove the PCM, turn the PCM retaining screw with a screwdriver 1/4 turn counterclockwise and remove the PCM from the electronic brake control module and PCM bracket assembly.
10. Disconnect the connectors from the PCM and remove the PCM from the vehicle.
11. Make sure the anti-rattle foam is secure in the electronic brake control module and PCM bracket assembly before installation of the new PCM. If the foam is present, proceed to step 12. If the foam is not present, proceed to steps 11a through 11c and install an adhesive-back foam shim stock.
a. Cut five, 2-3/4" inch pieces of Kent Industries, 1-1/4" x 1/8" Adhesive-Back Shim Stock (P/N 451) or equivalent.
b. Install two pieces of the adhesive-back shim stock to the front-side (vertical side as viewed in vehicle) of the electronic brake control module and PCM bracket assembly, starting 1/2 inch in from the outer edge. The second piece should be spaced 1/2 inch in from the first piece before installing. (Refer to illustration.)
c. Install three pieces of the adhesive-back shim stock to the top-side (horizontal side as viewed in the vehicle) of the electronic brake control module and PCM bracket assembly, starting one inch in from the outer edge. The second and third pieces should be spaced one inch away from the other pieces before installing. (Refer to illustration.)
NOTICE: To prevent PCM pin damage, make sure connectors are aligned with PCM connector housings before installing the connectors.
12. Plug the connectors into the new PCM and push the PCM up into the bracket assembly until two clicks are heard.
IMPORTANT: To help prevent PCM pin damage, a Mylar strip may be over the connector pins on the PCM. Do not remove this Mylar strip. When the connector is installed, it will push the Mylar strip to the base of the connector.
13. Turn ignition On, press F3 to continue with PCM reprogramming.
14. Select the calibration shown on the following chart for the vehicle being worked on, then press enter.
15. On automatic transaxle equipped vehicles, you will be prompted to select a valid PCM/TC calibration. Highlight the appropriate calibration then press enter. If valid PCM/TC calibration is already in box, this screen will not be displayed.
16. When the download is complete, turn ignition Off for 30 seconds and select F3 to continue.
17. Select F10 to return to main menu.
18. Verify new vehicle software has been loaded:
a. Select Dynamic Display
b. Select View Serial Data.
c. Select PCM/EC.
d. Select Vehicle ID. Verify the following information is correct:
NOTE: VIN must match vehicle being serviced.
19. To complete the repair, affix the Campaign Completion Label, as described under campaign procedures. "Campaign completion label"
20. If the vehicle is registered in California, fill out a "Vehicle Emission Recall Proof of Correction" certificate, as described under campaign procedures.
