Part 3

WARNING STATE SCREEN:





The WARNING STATE screen displays data related to pressure/temperature warning conditions detected by the TPMS sensors.

The F1 and F3 keys have the same functions as noted under the CURRENT DATA screen.

ACTUATION TEST SCREEN:





The ACTUATION TEST screen is used to test the function of the TPMS warning lamps. The F1 and F2 keys are used to START and STOP the tests.

ECU INFORMATION SCREEN:

The ECU INFORMATION screen has two menu options:





TPMS CONTROL MODULE INFO displays ECU configuration data.

CURRENT SENSOR ID shows the ID's of the currently registered sensors.

SPECIFIC DATA WRITING SCREEN:

Four options are available in the Specific Data Writing Screen:





01. VEHICLE NAME

02. WHEEL SENSOR ID

03. VIN

04. MODE CONFIGURATION

VEHICLE NAME SCREEN:

If a TPMS ECU is replaced the vehicle name must be written to the ECU to allow the system to operate properly.





1. After sensor ID registration access the VEHICLE NAME screen.

2. Press ENTER after reviewing the text message.

3. The vehicle name to be written to the ECU is pre-configured. The two-letter code "LD" represents 2007 and later Spectra. Press ENTER to write the two-letter vehicle name to the ECU; press ENTER again to confirm the choice. The TPMS Exciter will report the status of the operation (success or failure).

WHEEL SENSOR ID SCREEN:





This screen is used to manually enter the 8 alphanumeric characters for each sensor into the ECU's memory. After reading each sensor ID using the TPMS SNSR CONFIG (EXCITER) function the ID's can be manually entered and stored from this screen. Follow the prompts on the TPMS Exciter screen to complete this operation.

Note:
The WHEEL SENSOR ID screen is used as an alternate method to configuring sensor ID's. The primary method is to use the REGISTER SENSOR function.

VIN Screen:





The VIN screen provides a method of storing the Vehicle Identification Number within the TPMS ECU. The function keys support the entry of letters; the numeric keypad is used for number entry. Press the ENTER key to store the VIN. (The user will be prompted to confirm by pressing ENTER a second time)

Note:
This operation should be performed whenever a TPMS ECU is replaced.

MODE CONFIGURATION SCREEN:





This screen is used to change the TPMS ECU's mode to NORMAL. New TPMS ECU's are shipped in "PROGRAM AND TRANSPORT MODE" and MUST be set to NORMAL mode before the TPMS will function correctly. Press the ENTER key to set NORMAL mode; press ENTER again to confirm. Following this operation, turn the TPMS Exciter OFF, disconnect the tool from the OBD-II connector, and turn the ignition key OFF for 10 seconds.

Note:
This operation should be performed whenever a TPMS ECU is replaced. A TPMS ECU that is not in NORMAL mode may illuminate the TPMS warning lamp on the instrument panel.

TIRE SNSR CONFIG (EXCITER) FUNCTIONS:





Select 02. TIRE SNSR CONFIG (EXCITER) from the TMPS DIAGNOSIS menu.

TIRE SENSOR CONFIG (EXCITER)





Menu contains two items

01. SET SENSOR STATUS is used to read data from individual sensors.

02. REGISTER SENSOR is used to capture the ID's of all 4 sensors and register the sensors to the TPMS ECU without the need for manual data entry.

SET SENSOR STATUS FUNCTION

Disconnect the DLC cable. Place the TPMS Exciter within 3 inches of the valve stem; point the arrow at the top of the TPMS exciter directly at the valve stem.

*NOTICE:
The distance from the TPMS Exciter to the valve stem will have an effect on the sensor response time. The farther away the tool is positioned from the sensor, the longer the response time For best results, keep the TPMS exciter within 3 inches of the valve stem when performing sensor communication functions.








Press ENTER at the "FUNCTION DESCRIPTION" screen. The TPMS tool will display "NOW COMMUNICATING" and the red "LF" LED will illuminate. Once the sensor responds, the green "RF" LED will momentarily blink and the sensor data will be displayed.





Sensor data displayed will include the Sensor ID, Pressure, Temperature and Battery information. Sensor configuration data will also be displayed.

To retrieve data from another sensor, the F1 (CLR) key may be used to restart the sensor communication process.

If the "Sensor Option" Parameter shows a "HIGH" status, the sensor will need to be reset:

1. Place the TPMS Exciter within 3 inches of the valve stem; point the arrow at the top of the TPMS exciter directly at the valve stem.

2. Press F3 (LOW), and continue to aim the TPMS exciter at the valve stem as indicated above. The TPMS exciter will switch the sensor from HIGH to LOW mode. Once the sequence is complete, the new sensor data will be displayed.

REGISTER SENSOR FUNCTION:





This function is used to capture the sensor ID's then register these ID's within the control unit.

Note:
DTCs should be cleared before performing this procedure.

To perform the REGISTER SENSOR function:

1. Select 02 REGISTER SENSOR from the TIRE SNSR CONFIG (EXCITER) menu.





2. Press ENTER at the text screen. Place the TPMS Exciter within 3 inches of the valve stem; point the arrow at the top of the TPMS exciter directly at the valve stem of the left front wheel.





3. Press ENTER. The sensor ID for the LF wheel will be read and displayed.

4. Following the prompts displayed on the TPMS Exciter, retrieve the sensor IDs from the right front, right rear, and left rear wheels.











5. Once all 4 sensor IDs are retrieved, connect the DLC cable to the TPMS Exciter and the OBD-II DLC.





6. Turn the ignition key ON. Wait for the bulb check sequence to complete. Press the F6 key on the TPMS Exciter to write the sensor IDs to the TPMS ECU. Press the ENTER key to confirm.





7. Once the TPMS Exciter completes the operation, turn the ignition key OFF, and then back ON.

8. Wait a minimum of 4 minutes.

9. Access the Current Data screen. Verify that a pressure value and a temperature value is displayed for each sensor.

10. Verify normal TPMS operation as described in the NORMAL OPERATION CONFIRMATION section of this TSB.
