4. GDS TPMS Functions
NOTE:
Before performing diagnostics with GDS, ensure that the GDS software is up to date with the latest version.
GDS and TPMS Tool Functions:
^ Read/write wheel sensor IDs
^ Wheel Sensor ID Writing
^ Monitor TPMS system components current data - Current Data
^ Read wheel sensor pressure, temperature, battery level, mode (high/low) data - Current Data; Set Sensor Status
^ Register wheel sensors to TPMS module
^ Set TPMS control module mode - Storage/Normal
^ Set TPMS wheel sensor status - High/Low-Line
^ Test TPMS system warning lamps
^ Check and clear DTCs
NOTE:
These options are accessible through the "Vehicle S/W Management" tab. Please see the following screen shot. Alternatively, this screen can be accessed from the main GDS page by selecting "System Option."
NOTE:
The GDS TPMS tool must be powered ON, be in a good state of charge, and be connected to the GDS via the USB port for the systems to communicate.
NOTE:
When using the GDS TPMS tool, ensure that the vehicle is not located near any others. It is possible that the tool may read another vehicle's TPMS sensors. Allow a minimum distance of 10 feet when reading sensors between cars.
a. Register Sensors
6. To register TPMS wheel sensors using the GDS and GDS TPMS tool, click the "Vehicle S/W Management" tab along the top of the screen. Select "Register Sensor."
7. With the vehicle ignition ON, engine OFF, disconnect the GDS TPMS tool from the GDS, as instructed.
8. The TPMS tool's red LED will blink a specific number of times, indicating which number sensor it is ready to read (#1-#4). Starting with sensor #1 (front left), hold the tool within 3 inches of the wheel sensor and press the ENTER key.
9. The red LED will turn on solidly without blinking for a few seconds. When it starts blinking again, it is ready to read the next sensor.
NOTE:
Depending on the system, it may take up to 2 minutes to read a TPMS wheel sensor.
10. Continue to read the sensors in the order defined by the GDS (FL, FR, RR, RL).
11. After reading all sensors, reconnect the TPMS tool to the GDS. The GDS will display the read sensor IDs. Click "Write" to complete the registration process.
b. Set Sensor Status
1. To set the wheel sensor status, select "Set Sensor Status" from the Vehicle S/W Management screen.
2. Similar to registering sensors, the GDS will prompt the user to walk around the vehicle starting at the front left wheel to read the TPMS wheel sensors.
3. When finished reading the sensors, the GDS will display the 4 sensors information as shown.
4. From this screen, the user is able to view each sensor��s status: ID; temperature, pressure, mode (high or low), etc.
IMPORTANT:
It is critical that the sensor status is correct according to the vehicle TPMS system (high or low line). If it is set incorrectly the TPMS malfunction indicator will illuminate. Verify that the wheel sensors are in the correct mode.
NOTE:
When reading the sensors under Set Sensor Status, the TPMS tool will set the wheel sensor to the appropriate mode (high or low) according to the vehicle selected.
c. Set TPMS Module Mode
NOTE:
TPMS module mode setting is required for TRW systems only. This is necessary to do when replacing a TRW TPMS module, as the modules are shipped in storage mode. The TPMS malfunction lamp will blink when a new module is installed. This indicates that the module mode must be changed from storage to Normal mode.
NOTE:
When replacing a TPMS module for a TRW system, refer to "F TRW TPMS sensor and Module Replacement procedure."
1. To set the TPMS module mode, select "TPMS Mode Configuration" from the Vehicle S/W Management screen.
2. With the vehicle ignition ON, engine OFF, use the drop down menu to select the "Normal" mode for the TPMS Control Module.
d. Check and Clear DTCs
1. To set the wheel sensor status, select the "DTC" tab along the bottom of the GDS screen.
2. The DTC screen will display any codes present, their description, and state (current or history).
To clear DTCs, select "Erase ALL DTC."
