Service Procedure

CAUTION:
Front Control Module (FCM) damage may occur if the module case comes in contact with the battery while the battery cables are still connected. Always disconnect the battery negative cable prior to removal of the FCM.

1. Disconnect and isolate the negative battery cable.

2. Partially remove the Integrated Power Module (IPM) from the engine compartment using the following procedure:

a. Remove the IPM cover by pulling up on the cover tabs and pivoting the cover outward.





b. Remove the nut from the IPM B+ terminal stud (Figure 1).

c. Remove the cable terminal from the IPM B+ stud.





d. Using a suitable flat bladed tool, depress the three retaining clips and lift the IPM straight up off of the bracket tabs (Figure 2).

e. Lay the IPM on its side to expose the FCM Julian date code label (Figure 3).





3. Inspect the Julian date code on the label located on the backside of the FCM (Figure 3).

CAUTION:
The FCM has two labels. One label is located on the front side of the FCM. The second label is located on the back side of the FCM between the module electrical connectors. The Julian date code label to be inspected is located on the back (electrical connector) side of the FCM.

NOTE:
The Julian date is the 6th, 7th, and 8th character in the bottom row of numbers (Figure 3).

> If the Julian date code is lower than 337 or higher than 339 the FCM does not require replacement. Continue with Step 15 of this procedure.

> If the Julian date code is 337, 338, or 339 the FCM must be replaced. Continue with Step 3 of this procedure.

4. Disconnect the two IPM electrical connectors (Figure 3).

5. Disconnect the two FCM electrical connectors (Figure 3).

6. Remove the IPM assembly from the vehicle.





7. Remove the four fasteners securing the FCM to the IPM (Figure 4).





8. Separate the original FCM from the IPM by pulling the two straight away from each other to disengage the electrical connector (Figure 5).

9. Transfer the plastic cover from the original FCM module to the new FCM module (Figure 4).

10. Connect the new FCM to the IPM by lining up the electrical connector and pushing the two modules together (Figure 5).

11. Install the four fasteners securing the FCM to the IPM (Figure 4).

12. Position the IPM into the vehicle.

13. Connect the two FCM electrical connectors (Figure 3).

14. Connect the two IPM electrical connectors (Figure 3).

15. Position the IPM over the three bracket tabs and apply downward pressure until the retaining clips snap securely into place (Figure 2).

16. Install the battery positive cable to the IPM B+ terminal stud.

17. Install the IPM B+ terminal stud nut (Figure 1). Tighten the nut to 105 in. lbs. (11 N.m).

18. Install and close the IPM cover ensuring the locking tabs snap firmly in place.

19. Connect the negative battery cable.

20. For vehicles that had the FCM replaced, reconfigure the FCM using the following procedure:

a. Connect the StarSCAN to the data link connector on the vehicle and the dealership network.

b. Turn the ignition to the "RUN" position.

c. Power "ON" the StarSCAN.

d. Starting at the StarSCAN "HOME" screen, select "ECU View".

e. Select "FCMCGW Central Gateway" from the list.

f. Select "Misc Functions".

g. Select "Restore Vehicle Configurations" from the list and press the blue "START" button in the upper right corner of the screen.

h. Follow the on-screen instructions to complete the reconfiguration process.

i. Disconnect the StarSCAN from the vehicle.
