1. Safety Precautions and Warnings To prevent personal injury or damage to vehicles and/or the scan tool, read this instruction manual first and observe the following safety precautions at a minimum whenever working on a vehicle: Always perform diagnosis or service in a safe environment. Wear safety eye protection that meets ANSI standards. Wear safety eye protection that meets ANSI standards. Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot engine parts.
2. General Information 2.1 TPMS system review A tire pressure monitoring system (TPMS) is an electronic system designed to monitor the air pressure inside the pneumatic tires on various types of vehicles. TPMS report real-time tire-pressure information to the driver of the vehicle, either via a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types — direct (dTPMS) and indirect (iTPMS).
When diagnosing TPMS systems, you should understand what the TPMS tell-tale light means. When turning the ignition OFF to ON, the TPMS tell-tale should come on, and then go off, which indicates the system is working fine. If the light stays on, there would be a pressure problem. If the light flashes, there would be a system problem, which can range from faulty sensors to sensors on the vehicle that haven’t been learned to that vehicle. 2.

4. TPMS Activation The MaxiTPMS® TS401 is a hand held tool used to activate all magnetic, frequency, and tire deflation triggered sensors used on vehicle tire pressure monitoring systems to get information such as sensor ID, tire pressure, tire temperature, sensor battery, and frequency. It also sends the sensor data to vehicle’s ECU to let the ECU learn the positions of sensors whenever tires and wheels are rotated or sensors are replaced. There are two means of activating a TPM sensor: A.
Figure 4.1 The selected vehicle is remembered by the tool when a test is commenced. Select by Make Figure 4.2 Select by Model Figure 4.
Select by Year Figure 4.4 3) Depending upon the reading mode (All Wheels or One Wheel), results are displayed in different manners. All Wheels Mode In this mode, the screen will display as below (Figure 4.5). The tool will do TPMS test in a sequence of FL (Left Front), FR (Right Front), RR (Right Rear), RL (Left Rear) and SPARE, if the vehicle has the option for the spare. Use the UP/DOWN SCROLL button to move to the desired wheel for testing.
the same procedure for the rest of the three or four wheels by pressing the UP/DOWN SCROLL button and then TEST button. The tool will send LF signal to trigger the sensor. Depending on the sensor type, the tool will activate the sensor on the first or last step. Once the sensor is successfully activated and decoded, the tool will display as below with an audible beep. (Figure 4.6) Figure 4.
Figure 4.7 In this mode, the tool will do TPMS test for each single wheel. Place the tool alongside the valve stem and point toward the sensor location and then press TEST button. Wait for test result before moving the tool. The tool will send LF signal to trigger the sensor. Depending on the sensor type, the tool will activate the sensor on the first or last step. Once the sensor is successfully activated and decoded, the tool will display as below with an audible beep. (Figure 4.8) Figure 4.
TABLE 1 POSSIBLE RESULTS FOR TESTING Icon Test Results Description √ Successful Sensor Read TPMS sensor is successfully activated and decoded. The tool displays the sensor information. X Failed Sensor Read If the search period expires and no sensor activation or decode, it may be wrong sensor fitting or non-functioning sensor. The tool displays a message “No sensor detected.”. In this case, repeat test to confirm the TPMS failure.
NOTE: With Ford Banded sensors, the tool should be held 180 degree away from the stem. Please refer to vehicle user’s manual. If the TPMS sensor requires a magnet, place the magnet over the stem and then place the tool alongside the stem, and press TEST button. Figure 4.9 If the TPMS sensor requires tire deflation (of the order of 10PSI), then deflate the tire and place the tool alongside the stem while pressing TEST button. Figure 4.
Figure 4.11 Sensor activation can be aborted at any time by pressing the N button. When the activation is aborted, the tool will return to the previous menu. By pressing the Y button, you may review information of all sensors tested. The screen will switch every five seconds. Figure 4.12 Figure 4.
