4. For Vehicles equipped with the "Auto-Up" front window feature, calibrate the door module using the following procedure:

a. Turn the ignition to the "Run" position.

b. Regardless of current window position, move the driver side front window upward until the window stalls in the full up position. Allow the window motor to stall for at least 2 seconds before releasing the window switch.

c. Move the driver side front window downward until the window stalls in the full down position. Allow the window motor to stall for at least 2 seconds before releasing the window switch.

d. Move the driver side front window upward until the window stalls in the full up position. Allow the window motor to stall for at least 2 second before releasing the window switch.

e. Repeat steps 4a. through 4d. to calibrate the module for the passenger side front window.

f. Verify the windows are properly calibrated by operating the "Auto-Up" feature on the windows. Repeat this procedure if the calibration failed.

5. For Vehicles equipped with Electronic Stability Program (ESP), calibrate the Steering Angle Sensor (SAS) using the following procedure:

CAUTION:
If the vehicle is equipped with Electronic Stability Program (ESP), once the battery is reconnected, the Steering Angle Sensor (SAS) within the Antilock Brake Module (ABM) needs to be calibrated. The SAS requires calibration (initialization) using the StarSCAN scan tool. If the SAS is not calibrated following battery reconnection, the ESP/BAS indicator lamp will flash continuously with no Diagnostic Trouble Codes (DTC's).

a. Position the front wheels straight ahead and center the steering wheel.

b. Connect the StarSCAN scan tool to the vehicle data link connector.

c. Turn on the StarSCAN and place the ignition in the "RUN" position.

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

e. Select "ABS Anti Lock Brakes".

f. Select "Misc. Functions".

g. Select "Initialize ECU".

h. Follow the StarSCAN on-screen instruction to complete the drive test.

6. Check and clear all Diagnostic Trouble Codes (DTC's) using the following procedure:

a. Starting at the "Home" screen, select "System View".

b. Select "All DTC's".

c. Select "Clear All Stored DTC's" and follow the StarSCAN on-screen instructions.
