1. Introduction
This manual provides comprehensive instructions for the safe and effective use of the JDIAG TPMS-19 Tire Pressure Monitoring System (TPMS) Relearn Tool. This device is designed to activate and relearn TPMS sensors in compatible vehicles, ensuring proper tire pressure monitoring functionality.
The JDIAG TPMS-19 tool is specifically designed for Ford, Lincoln, Mercury, and Mazda vehicles equipped with a Tire Pressure Sensor system. It is used for tasks such as exchanging winter and summer tires, replacing damaged tire sensors, or turning off the TPMS warning light.

2. Vehicle Compatibility
The JDIAG TPMS-19 tool is compatible with various Ford, Lincoln, Mercury, and Mazda vehicles that utilize a Tire Pressure Sensor system. It is a replacement for part numbers 8C2Z1A203A, 8C2Z-1A203-A, 8C2T-1A203-AB, and TPMS19.
This tool is suitable for F150 series vehicles, cars, SUVs, pickups, and light trucks. Please refer to your vehicle's specific model year and TPMS system requirements to confirm compatibility.

3. Setup and Preparation
Before initiating the TPMS relearn procedure, ensure the following:
- The vehicle is parked on a level surface.
- The ignition is off.
- All doors are closed.
- The parking brake is engaged.
- The JDIAG TPMS-19 tool has sufficient battery power.
The relearn procedure should ideally be performed outdoors, not inside a garage, to avoid potential signal interference.

4. Operating Instructions
Follow these steps to perform the TPMS relearn procedure:
4.1 Entering TPMS Learning Mode (Vehicle Specific)
The method to enter TPMS learning mode varies by vehicle model. Consult your vehicle's owner's manual for the exact procedure. A common method for many Ford vehicles is as follows:
- Ensure the vehicle is off and all doors are closed.
- Insert the ignition key (if applicable) but do not start the engine.
- Press and release the brake pedal once.
- Cycle the ignition switch from OFF to RUN three times, ending in the RUN position. (For push-button start, press the start button without pressing the brake pedal to cycle between OFF and RUN).
- The vehicle horn will typically honk twice, and the instrument cluster display will show "Train Left Front Tire" or similar message, indicating it is in TPMS learning mode.

4.2 Using the JDIAG TPMS-19 Tool
Once the vehicle is in TPMS learning mode, proceed with the following steps using the JDIAG TPMS-19 tool:
- Start with the Left Front tire. Position the antenna of the JDIAG TPMS-19 tool against the tire sidewall, near the valve stem.
- Press and hold the green button on the tool. The tool's indicator light will illuminate.
- Hold the tool in place until the vehicle horn honks. This indicates that the sensor has been successfully registered.
- Move to the Right Front tire and repeat steps 1-3.
- Continue to the Right Rear tire and repeat steps 1-3.
- Finally, move to the Left Rear tire and repeat steps 1-3.
- After all four sensors are registered, the vehicle horn will honk twice, and the instrument cluster display will show "Training Complete" or similar message.

5. Maintenance
To ensure the longevity and proper function of your JDIAG TPMS-19 tool, observe the following maintenance guidelines:
- Cleaning: Wipe the tool with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Storage: Store the tool in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Replacement: The tool is powered by a lithium metal battery. If the tool's indicator light does not illuminate or is dim, the battery may need replacement.
5.1 Battery Replacement
To replace the battery:
- Carefully open the back cover of the product.
- Unplug the old battery from the circuit board.
- Connect the new lithium metal battery, ensuring the positive and negative poles are correctly aligned.
- Close the back cover securely.

6. Troubleshooting
If you encounter issues during the TPMS relearn process, consider the following:
- Tool Not Activating Sensor:
- Ensure the tool's antenna is correctly positioned against the tire sidewall near the valve stem (refer to Figure 7).
- Verify the vehicle is correctly in TPMS learning mode (horn honked, display message present).
- Check the tool's battery. Replace if necessary.
- Perform the reset outdoors, away from large metal structures or other electronic devices that might cause interference.
- Vehicle Not Entering Learning Mode:
- Confirm the ignition cycling and brake pedal sequence is performed accurately and within the specified time frame (often within 5-10 seconds).
- Ensure all doors are closed and the parking brake is engaged.
- Consult your vehicle's owner's manual for the precise procedure for your specific model.
- TPMS Light Remains On After Relearn:
- Ensure all four tires were successfully registered (vehicle honked after each tire).
- Verify that the installed TPMS sensors are original OEM sensors and are properly programmed for your vehicle. Aftermarket sensors may require specific programming or may not be compatible.
- Check tire pressures to ensure they are at the recommended levels.
- If the issue persists, there may be a fault with a sensor, the TPMS module, or wiring, requiring professional diagnosis.
