4. Operating Instructions: TPMS Relearn Process

The U508 tool simplifies the TPMS relearn process into three main steps. Note that specific vehicle procedures to enter 'TPMS Learning Mode' may vary. Always refer to your vehicle's owner's manual for precise instructions.

Figure 3: Visual representation of the 3-step TPMS relearn process.

1. Step 1: Set Your Car into TPMS Learning Mode
   Consult your vehicle's owner's manual for the exact procedure to enter TPMS learning mode. For some vehicles (e.g., Subaru, Chrysler, Dodge), an additional OBDII Scan Tool (not included) may be required to initiate this mode.
2. Step 2: Position the Tool
   Hold the U508 tool against the sidewall of the tire, near the valve stem. Ensure the antenna is in the correct position, parallel to the valve stem, as shown in Figure 4.
3. Step 3: Activate the Sensor
   Depress the learn button on the U508 tool while holding it against the tire sidewall. Continue holding until the vehicle's horn bleeps once, indicating successful activation of that sensor. Repeat this process for all tires in the specified order (typically Front Left, Front Right, Rear Right, Rear Left).
