Service Procedure

For 2011 model year vehicles, begin with Section A. Replace Tire Pressure
Monitor Sensors of the service procedure.

For 2012 model year vehicles, begin with Section C. Reprogram the Body
Control Module (BCM) of the service procedure.

A. Replace Tire Pressure Monitor Sensors (2011 Models Only)

1. Raise the vehicle on an appropriate hoist.

2. Remove all four tire/wheel (and the spare tire if equipped with a full size spare tire) assemblies.





3. Place a mark on the tire sidewall at the valve stem to ensure that the tire orientation remains the same when inflating the tire (Figure 1).





4. Remove and discard the valve stem core (Figure 2).





5. Using a tire machine, unseat the outer bead of the tire from the wheel, following tire changer manufacturers instructions, while paying special attention to avoid damaging the pressure sensor (Figure 3).

6. Place a rag under the tire pressure sensor to prevent the sensor from falling into the tire





7. Remove and discard the original tire pressure sensor retaining screw and sensor body (Figure 4).





8. Using a valve stem tool, remove and discard the valve stem (Figure 5).

9. Wipe the area around the tire pressure sensor mounting hole in the wheel clean.

10. Insert the new tire pressure sensor through wheel keeping the pressure against the rear of metal valve stem. The potted side of tire pressure sensor is to be positioned toward the wheel.





12. Install the tire pressure sensor retaining nut by hand (Figure 6).

13. While holding the tire pressure sensor in position, tighten the tire pressure sensor retaining nut to 53 in.lbs. (6 Nm).

CAUTION:
Do not over tighten the tire pressure sensor retaining nut, tire pressure sensor separation from the valve stem could occur.

14. With the mark made in Step 3 lined up with the valve stem, inflate the tire to seat the tire bead to the rim following the tire changer manufacturers instructions.

CAUTION:
Pay special attention to avoid damaging the new tire pressure sensor.

15. Adjust the tire air pressure to that listed on the Tire Inflation Pressure Label (Placard) provided with vehicle (usually applied to driver's side B-pillar).

16. Balance the tires using the following procedure:

a. Remove and discard all of the original balance weights from the wheel.





b. Mount the wheel/tire assembly to the tire balancing machine (Figure 7).

c. Using a small screwdriver or pick, remove any stones that are lodged in the tread of the tire.

d. Balance the wheel/tire assembly following the tire balancing machine manufacturers instructions.

e. Remove the wheel/tire assembly from the balancing machine.

f. Repeat Steps 16a through 16e on all of the remaining wheel/tire assemblies.

17. Install the wheel/tire assemblies on the vehicle. Tighten the lug nuts to 140 ft. lbs. (190 Nm).

18. For vehicles with a full size spare: place the spare tire back into the vehicle.

19. Lower the vehicle from the hoist.

20. Use the following procedure to program the new tire pressure sensors:

a. Using the TPM-RKE Analyzer 9936, enter the vehicle information into the TPM-RKE Analyzer to create a session to record the tire pressure sensor ID code for each wheel.

b. Place the sensor against the tire sidewall, at the valve stem, and press the start button.

c. After the Analyzer records the ID number, enter the tire location into the analyzer.

d. Repeat Steps 20b. through 20c. on all of the remaining tires.

e. Open a wiTECH session

f. Connect the wiTECH VCI pod to the vehicle data link connector located under the steering column.

g. Connect the TPM-RKE Analyzer 9936 to the wiTECH laptop computer.

h. From the main menu screen, select the "TPM" icon.

i. Select the "Misc. Tab".

j. Select "Program Tire Sensor ID with TPM tool"

k. Follow the screen prompts to complete the programming of the new tire pressure sensors.

l. Clear all Diagnostic Trouble Codes (DTCs).

21. Continue with Section B. Reprogram the Instrument Panel Cluster (IPC).

B. Reprogram the Instrument Panel Cluster (2011 Models Only)

1. Starting from the "Vehicle View" screen, click on the "IPC" icon.

2. Select the "FLASH" tab.

3. Select the flash file from the list and click on the green arrow to start the flash process.

4. Follow the screen prompts.

5. Clear all Diagnostic Trouble Codes (DTCs).

7. Continue with Section C. Reprogram the Body Control Module.

C. Reprogram the Body Control Module (All Models)

1. Open a wiTECH session and connect the wiTECH VCI pod to the vehicle data link connector located under the steering column.

2. From the "Vehicle View" screen, click on the "BCM" icon.

3. Select the "FLASH" tab.

4. Select the flash file from the list and click on the green arrow to start the flash process.

5. Follow the screen prompts.

6. Clear all Diagnostic Trouble Codes (DTCs).

7. Remove the wiTECH VCI pod from the vehicle and return the vehicle to the customer.
