Service Procedure

1. Raise the vehicle on an appropriate hoist to a comfortable work height.

2. Remove tire and wheel assembly from the vehicle.





3. Mark the location of the tire to the wheel and the wheel weight to the wheel (Figure 1).

4. Remove the valve stem core to deflate the tire.

5. Break the outside bead of the tire from the wheel following tire changer manufacturers instructions.

CAUTION:
When breaking the tire bead loose from the wheel rim, avoid using the Bead Breaker in the area of the sensor.





6. Push the sidewall of the tire down at the sensor and place two small blocks of wood between the tire and rim (Figure 2).

7. Remove sensor nut that retains the sensor to the wheel.

8. Carefully remove the sensor from the wheel.

9. Wipe area clean around sensor/valve stem mounting hole in wheel.

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

11. Install the sensor nut by hand.

CAUTION:
Before tightening the sensor nut, push downward on the sensor housing so it is flush with interior contour of wheel.





12. While holding sensor in position, tighten sensor nut to 71 in. lbs. (8 N.m) (Figure 3)

CAUTION:
Over-tightening the sensor nut may result in sensor separation from the valve stem.

13. Remove the two wood blocks from between the wheel and tire (Figure 2)

14. Inflate the tire to seat the tire bead to the rim.

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

NOTE:
Make sure original style valve stem cap is securely installed to keep moisture out of sensor.

16. Repeat Steps 3 through 15 on the remaining three tire and wheel assemblies.

17. Install the tire and wheel assemblies on the vehicle. Tighten the lug nuts to 110 ft. lbs. (150 N.m).

18. Lower the vehicle from the hoist.

19. Connect the StarSCAN to the vehicle, turn the ignition to the "RUN" position and power up the StarSCAN. Continue with Step 20 of this procedure while the StarSCAN is powering up.

20. Perform the following procedure to program the sensor identification numbers into the vehicle module:

a. Turn on the TPM-RKE analyzer (special tool 9936) by pushing the red power button on the keypad.

b. Select "New Session" on the screen and then push the "Select" button.

g. Place the probe end of the analyzer by the valve stem of the wheel and press the green "TEST" button to scan the tire pressure sensor (Figure 4). Do not move the analyzer until the green pass light illuminates.

h. Press the "Select" button.

i. Select the tire location description on the screen that matches the tire that was scanned and press the "Select" button.

j. Repeat Steps 20g. through 20i. on all remaining wheels.





k. Connect the TPM-RKE Analyzer (9936) to the StarSCAN (Figure 5).

l. Starting at the StarSCAN "Home" screen, select "ECU View".

m. Select "TPM Tire Pressure Monitor".

n. Select "Misc. Functions"

o. Highlight "Program Tire Sensor ID w/TPM Tool" from the list on the screen.

p. Press the Blue "START" button on the StarSCAN screen.

q. Follow the screen prompts to enter the tire pressure sensor ID's into the vehicle module.

r. Turn the ignition "OFF" and remove the StarSCAN from the vehicle.
