How to use Foxwell NT1001 TPMS trigger tool
This post will guide you how to use the TPMS trigger tool to activate and decode TPM sensor data.
The NT1001 is designed to activate all know TPM sensors and decode data including sensor ID, tire pressure, temperature, battery condition, and OE part number, and to warn of a wrong sensor installed, missing or faulty sensor, duplicate ID, and incorrect sensor mode.
It typically tests a vehicle by the following two methods:
● All wheel mode
● One wheel mode
Activation in All Wheel Mode
The all wheel mode provides a vehicle icon on the screen to give user prompts for each wheel. In this mode, each TPM has wheel locations of LF (Left Front), RF (Right Front), RR (Right Rear),
LR (Left Rear) and spare (if the car has a spare tire).
1. In all wheel mode, the solid spot flashes at the wheel to be tested. Depending on the sensor type, place the tool to the correct position to insure sensor activation and decode. Below is a chart illustrating how to correctly place the tool.
| No. | Sensor Type | Illustration | Description |
| 1 | LF Activated Sensors |
 |
The tool should be placed alongside the valve stem. |
| Ford branded LF Activated Sensors |
 |
The tool should be held 180°away from the valve stem. |
|
| 2 | Magnet Activated Sensors |
 |
If the TPM requires a magnet, place the magnet over the stem and then place the tool alongside the stem |
| 3 | Delta P activated sensors |
 |
If the sensor requires tire deflation (of the order of 10PSI), the icon .png) will appearon screen. Please deflate the tire and place the tool alongside the stem |
2. Press Test to test the TPM. If test passes, TPM data is briefly displayed for 3 seconds and then the solid spot on the vehicle icon moves around to prompt that the next wheel should be tested. Or manually move around vehicle using UP/DOWN arrow keys.
3. TPM data is stored and can be accessed by selecting a wheel location and press the YES key.
4. Depending on test results, one of the following possible scenarios may display.
| No. | Sensor Type | Illustration | Description |
| 1 | Successful Sensor Read |  |
TPMS sensor was successfully activated and decoded. The NT1001 emits a series of tones and displays pressure at wheel location. |
| 2 | Failed Sensor Read |  |
The search period expires without reading a TPM. The NT1001 emits a single audible beep and displays “No sensor detected.” Repeat the test process to verify. |
| 3 | Duplicate ID |  |
A sensor with a duplicate ID has been read. The NT1001 emits three audible beep and displays “Sensor ID duplicate.” Clear data and re-read sensors. |
NOTE: Operator can press the NO key to abort the sensor activation and return to the previous menu at any time.
Activation in One Wheel Mode
This section illustrates how to test TPM sensor in one wheel mode. In this mode, TPM data is displayed and stored immediately.
1. In one wheel mode, the screen displays as below when the TPM sensor is selected.
2. Refer to Table 4-1 in page 12 to correctly place the trigger tool and press the Test key.
3. The tool moves to next wheel to be tested automatically or manually select a wheel to test using UP/DOWN arrow keys. Repeat the steps to complete test of all wheels.
4. Press YES key to review test results.
[Pos] – Indicates the wheel sensor position.
[ID-H/D] – Shows sensor ID data.
[KPa/Psi/Bar] – Indicates wheel pressure.
[℃/℉] – Indicates wheel temperature.
[BAT] – Indicates battery condition.
[Fre.] – Indicates the frequency of the sensor.
NOTE: Anytime while doing the TPMS test, press HELP key to read the sensor make, OEM part no., and relearn information for the vehicle being tested.
NOTE: Different ID format, pressure and temperature units will display at the title bar according to the device’s system setting, please refer to 2.7 Settings of the user manual for detailed guidance.
