An auto relearn procedure is when a vehicle has the ability to learn single or multiple TPMS sensor IDs without the need of performing the relearn procedure with a TPMS tool. Furthermore, a technician can adjust the inflation pressure, rotate or replace sensors and the TPMS system will reset itself after the vehicle has been driven for a period of time. However, before servicing the tires/wheels, it is always recommended to use a TPMS tool to trigger each of the vehicle’s sensors to make sure they are working properly.

For example, a 2008 Dodge Charger requires the following auto relearn procedure:

• Inflate all tires
• Drive for 20 minutes

There are two types of TPMS systems: direct TPMS and indirect TPMS. Direct TPMS systems use TPMS sensors inside the wheel to accurately report pressure data to the vehicle’s ECU in real time. Direct systems include Asian, Domestic and European vehicles. An indirect TPMS system uses an ABS system to monitor the speed of the wheel in order to approximate tire pressure. Indirect systems include Asian and some European vehicles.

• A tire “naturally” loses 0.2 atmosphere (2.9 PSI) every 3 months.
• 85% of all tire blasts are preceded by a “slow” puncture.
• An underinflated tire is not only dangerous because it can explode, it is also dangerous for the stability of the vehicle, and penalizes the consumption and the total life of the tire.

• It is recommended to program the sensors before mounting to in the tire
• Once aftermarket sensors have been programmed, verify them.
  • In the VT56 tool, go to CHECK TPM > then select the make, model and year
  • In the VT55 tool go to CHECK SENSOR then select the make, model and year
  • In the VT36 tool go to PROGRAM SENSOR then select the make, model and year (Aftermarket version only)
• The programmable sensors should react exactly the same way as their OE original sensors.

An OBDII relearn procedure requires a TPMS diagnostic tool to transfer new sensor IDs directly to the vehicle’s ECU. The user will need to trigger each TPMS sensor, connect to the vehicle’s OBD port, then follow the step-by-step instructions on the tool. The new TPMS sensor IDs are then transferred to the vehicle. Most Asian and specialty European vehicles require OBD relearn.

For example, a 2011 Toyota Camry requires the following OBDII relearn procedure:

• Inflate all tires
• Read all sensor IDs using TPMS diagnostic tool
• Connect tool to OBDII port
• Reset ECU with tool
• Turn ignition OFF, then ON
• Drive at 12 mph for up to 5 minutes

Image of VT56 screen displaying auto relearn procedure for 2011 Toyota Camry

Manual and stationary relearn systems can sometimes take several steps to relearn the TPMS system. TPMS diagnostic tools have the step-by-step instructions for auto, stationary and OBD relearn, however, the steps involved can be long and complicated. OBD relearn procedures are becoming standard in a shop environment for many reasons. First and foremost, it is the easier to work with since the same procedure can be performed no matter what the vehicle type is. Secondly, OBD relearn saves time and confusion for the technician since there are less steps to perform. According to amra.org, 62% of vehicles require a TPMS diagnostic tool and 27% require OBD functionality. It is important to have a reliable TPMS diagnostic tool with excellent OBD coverage to keep up with the growing industry of TPMS.

Did you know? ATEQ has the largest OBD coverage (86% and growing) to help shop owners save time and money!

Vehicles with direct-type TPMS systems are equipped with TPMS sensors. If a TPMS sensor is not working, it must be replaced before a relearn procedure can be performed. The damaged TPMS sensor can be replaced by an OE sensor or an aftermarket sensor.

There are different types of aftermarket TPMS sensors including universal, configurable and programmable sensors. OE sensors, universal and configurable sensors have new sensor ID’s already encoded within the sensor and need to be activated by using a TPMS diagnostic tool. Programmable TPMS sensors require a TPMS diagnostic tool to create new sensor ID’s or transfer sensor ID’s from the old sensor.

For multi-brand repair shops, a mix of universal sensors and OE sensors is often required. Our tools support the largest aftermarket sensor list on the market including, Alligator sens.it, BWD Standard OE and Standard QWIK, Continental REDI-Sensor, Dorman Direct Fit, Hamaton U-Pro, HUF IntelliSens, MOBILETRON, NAPA QWIK and OE Design, Orange Simple Sensor, Schrader EZ-sensor, SMP Standard OE and Standard QWIK and STEELMAN Select.

Some important features of the ATEQ VT56 and VT36 when working with TPMS sensors include:

• Displays sensor data including sensor ID, psi, frequency, temperature and battery life (some sensors do not display temperature and battery life data)
• Sensor part number lookup by vehicle make, model, year (MMY) selection
• Program sensor by sensor or vehicle MMY selection
• Step by step OBD, Auto, Stationary and Indirect training

A stationary relearn procedure allows new TPMS sensor IDs to be transferred to the vehicle’s ECU without driving a vehicle. This type of relearn procedure requires a TPMS activation tool to trigger the sensors when the vehicle is in learn mode either by using a TPMS diagnostic tool or a diagnostic scan tool. The vehicle then uses a radio frequency (RF) signal to communicate with the vehicle’s ECU to establish which sensor is in which specific location.

For example, a 2014 Ford Escape (with standard ignition) requires the following stationary relearn procedure:

• Inflate all tires
• Turn ignition off
• Press and release brake pedal
• Cycle ignition from “off” to “run” three times ending in “run”
• Press and release brake pedal
• Turn ignition off

Image of VT56 screen displaying auto relearn procedure for 2014 Ford Escape (with standard ignition)

The proper steps to reset a TPMS system for a vehicle with direct-TPMS:

• Use a TPMS diagnostic tool to trigger and read sensor information before working on vehicle
• Perform service to vehicle’s wheels (air pressure adjustment, tire rotation, replace sensors, etc.)
• After the service has been performed, use a TPMS diagnostic tool to perform the correct relearn procedure to reset the TPMS system

The proper steps to reset a TPMS system for a vehicle with indirect TPMS:

• Perform the correct initialization procedure. This may require a TPMS diagnostic tool to find the steps involved to reset the system.

Possible cause: the protocol used is incorrect. Contact ATEQ.

When service has been performed to the vehicle’s direct TPMS system, such as air pressure adjustment, tire rotation or replacement of sensors, vehicles require a TPMS system relearn to be performed. A relearn allows the vehicle’s ECU to see the ID’s of each sensor in each wheel. Completing the relearn procedure clears TPMS diagnostic fault codes and allows the vehicle’s TPMS system to function properly.

Relearn procedures vary by manufacturer, so a technician must know which proper relearn procedure is necessary to put the vehicle in learn mode. Although relearn procedures differ from manufacturer to manufacturer, the three types of relearn procedures for direct TPMS systems are auto relearn, stationary and OBD. Furthermore, some vehicles may use a combination of two or more relearn types. Indirect TPMS systems use an initialization procedure which may require a TPMS tool to figure out the steps involved to reset the system.

The chart below represents the three types of TPMS relearn procedures within the market of Asian, Domestic and European vehicles equipped with direct TPMS systems.

Information from this chart was obtained from the ATEQ European database system

• Check that the power cable is connected
• Check power on (press on/off 3 sec.)
• Check that paper is present (check the direction of the paper out)
• Send a job to the printer

When WebVT displays “Searching device” or “Device not found” as an error message, you may need to re-install the USB drivers. Reasons for this error include:

• User is trying to install WebVT on new PC
• User did not have device or powered on or connected during WebVT installation

Please complete the following steps to correct the issue.

1. Download the USB drivers for your device. For the VT56, VT55, VT36, VT30, VT15, Mitsureset and Quickset, please download the following file: WebVT

Users “trigger” or “decode” the TPMS sensor within the wheel. This TPMS sensor is not physically reachable since it is mounted inside the tire. Therefore, decoding or triggering a sensor must be done wirelessly using a TPMS triggering tool.

The light will illuminate when a tire is low, and should eventually go out after a tire has been inflated to its recommended pressure according to the vehicle’s door placard. After starting a vehicle, a TPMS icon will turn on for a few seconds, however, if it stays on, it indicates that one or more of the tires on the vehicle is at least 25% below the recommended pressure. If the light flashes for approximately one to two minutes, it indicates there is a malfunction in the TPMS system.

There are numerous situations that can cause a TPMS warning light to come on or flash. Some TPMS problems include:

• Sensor batteries may be dead
• Valve itself may have physical damage, corrosion or missing components
• The TPMS system voltage supply, wiring or internal electronics may not be functioning properly
• The tires were serviced or rotated and the relearn procedure was not properly performed

Tire Pressure Monitoring System

IMPORTANT!

If the tool fails to connect to WebVT, ask your network administrator to check Wi-Fi router settings:

802. Router must support Wi-Fi 802.11 b/g/n standards
803. DHCP server: set to the default gateway option
804. MAC Address Filtering: Enabled
805. Wireless Access Point (WAP) mode: Enabled
806. Wi-Fi channels: Use channel 1, 6 or 11

A TPMS activation or trigger tool allows the user to activate or trigger the wireless tire pressure monitoring sensor mounted within a tire. For example, all TPMS sensors carry an internal battery that can drain while in storage. When a vehicle is manufactured in a plant, the TPMS sensors mounted within the tire are left in “sleep” mode when delivered to a workshop or dealer. Therefore, the TPMS activation tool is needed to “activate” or “wake up” TPMS sensors mounted within the tires.

• Upgrading your tool will always allow you to programme all most popular universal sensors and get access to new features.

  

Before contacting support, have you updated your software recently? The number one reason for ATEQ TPMS tool issues is outdated software. Update your tool’s software and check to see if your issue(s) continue.

If this happens in the beginning of the process:

• Verify that the aftermarket sensor is compatible. In the tool, check if the sensor brand is in the list of compatible sensors for the vehicle’s make, model and year.
  • In the VT56 go to PROGRAM > MAKE > then select the vehicle make, model and year
  • In the VT55 go to PROGRAM BLANK SENSOR > then select the vehicle make, model and year
  • In the VT36 go to PROGRAM SENSOR > then select the vehicle make, model and year (Aftermarket version only)
• If the sensor used is compatible, the tool database may be wrong. Contact ATEQ.

If this happens during the validation process:

• Verify that the aftermarket sensor is compatible.
  • In the VT56 go to PROGRAM > MAKE > then select the vehicle make, model and year
  • In the VT55 go to PROGRAM BLANK SENSOR > then select the vehicle make, model and year
  • In the VT36 go to PROGRAM SENSOR > then select the vehicle make, model and year (Aftermarket version only)
• If all the data is correct, one of the programmable sensor may be defect, please contact the sensor maker.

The aftermarket sensor cannot be programmed in the frequency required for that vehicle (315 or 434 MHz). The user should check if the sensor is compatible with the vehicle selected.

• If this happens during the upload process, verify that the aftermarket sensor reference is compatible in the tool. If all this data is correct, the sensor may be defective, please contact the sensor maker.
• If this happens during the verification process, the tool’s database may be incorrect. Please contact ATEQ.

• Check if the vehicle is equipped with sensors, or with an indirect system.

• In the VT56 tool go to SERVICE > then select the make, model and year
• In the VT55 tool go to CHECK SENSOR then select the make, model and year
• In the VT36 tool go to PROGRAM SENSOR then select the make, model and year
• In the VT30 tool go to VEHICLE SELECTION then select the make, model and year

• If you cannot detect the sensor, change the position of the tool against the tire. Wait until at least 35 seconds. Change the distance between the tool and the wheel.  
• Try ALL of the car’s sensors. It is VERY rare, that ALL sensors are dead. If the others respond, the sensor can be considered as defect. Please replace.
• If all else fails, the TPMS protocol used in the tool’s database may be wrong. Contact ATEQ.

Some first generations of TPMS sensors (such as Beru or Pacific) need to be put under pressure in order to be activated. The correct procedure, when the sensor is fitted in the wheel, is to inflate the wheel according to the tire placard. The user should trigger the sensor, and slowly deflate the tire simultaneously. After a few seconds, the sensor will respond. Enter the correct tire pressure.

• For the VT56, remove the rubber boot. You will locate the 4GB SD card on the right side. Push in the SD card to remove.

• For the VT55, remove the rubber boot. You will locate the 2GB SD card on the bottom of the tool. Push in the SD card to remove.

If your TPMS tool cannot activate or reset a sensor, we recommend updating your TPMS tool to include the latest TPMS sensors. With a growing TPMS market, new TPMS sensors are new to the market every day. ATEQ engineers are hard at work to make sure all known TPMS sensors are compatible with ATEQ TPMS tools.
ATEQ upgradeable TPMS tools such as the VT56, VT55, VT36, VT30 and VT15 are always compatible with the latest TPMS sensors released to the market.

There is new firmware available for the OBDII module, and the device is attempting to communicate with the vehicle and complete a firmware update at the same time. Simply power the tool off and then on again. Once the main menu is displayed, connect the OBDII module only to the device; leaving the other end disconnected from any vehicle. The OBDII module will be detected almost immediately by the tool and the firmware, and the update will begin. The update takes less than 60 seconds to complete. Once completed, disconnect the OBDII module and power the device off. The update is now complete.

A TPMS tool is needed for the following:

• Activate a newly mounted TPMS sensor
• Reprogram the vehicle’s ECU so the vehicle recognizes the new sensor when tires change order, switch from winter to summer tires, mount a new wheel to a vehicle, etc.
• Send TPMS sensor information to the vehicle’s ECU after activating and receiving the TPMS sensor information

ATEQ TPMS workshop tools: VT56, VT36, VT15

The tire pressure monitoring system (TPMS) primary function is to make the driver aware of the state of tire pressure within the wheels. Under normal system operations, the TPMS system will alert the driver when one or more affected tires PSI reading falls below 25% of the placard. When the tire sensor indicates “low tire pressure”, it sends a radio frequency (RF) signal of 315 or 433 MHz to the ECU on the vehicle that determines if the pressure is below the threshold, which then will indicate a TPMS symbol or position-specific display, depending on the vehicle.

In 2000, after Firestone recalled more than 6.5 million vehicles due to tread separation, the NHTSA (National Highway Traffic Safety Administration) issued the first version of the TREAD Act which required Tire Pressure Warning Systems to be implemented on all vehicles sold in the United States by the year 2008 including all passenger vehicles and light trucks with GVWR of 10,000 lbs. and less.

Advantages of a TPMS system:

• Warns user of underinflated tire
• Reduces the risks of accidents due to a tire failing
• Optimizes the fuel consumption as well as the tire life
• Reduces the risk of a slow puncture
• On the road, safety means respecting the tire pressure requirements made by the manufacturer of your car. Unfortunately, with today’s tires, it is almost impossible to visually distinguish a 50% underinflated tire

A TPMS equipped tire can display the TPMS sensor internal pressure and warns drivers when it reaches a low level by displaying a TPMS warning light.
