TPMS sensors: programming and relearn

New tire pressure sensors need two separate steps before your dashboard light goes out. Here’s what each one does, and how to get it done on your vehicle.

Programming the sensor

An aftermarket (universal) sensor ships blank. Programming loads it with the right protocol for your make, model and year, so it “speaks the same language” as your vehicle. It’s done on the sensor, before it’s installed in the wheel.

Relearning the vehicle

Each sensor has a unique ID. The relearn registers those new IDs in your vehicle’s computer, so it knows which signals to listen to and which wheel each one belongs to. It’s done on the vehicle, once the wheels are mounted.

Programmed isn’t the same as working. A sensor can be perfectly programmed and still trigger the TPMS warning light (the tire outline with an exclamation mark) if the vehicle hasn’t been relearned. Any time new sensors are installed, a relearn is required.

The three relearn methods

Every manufacturer sets its own procedure, and there’s no industry standard. Your vehicle will use one of these methods, or a combination of them.

Stationary. No tool is needed. The vehicle is put into learn mode through a sequence set by the manufacturer: turning the ignition on and off a set number of times, pressing the brake, using buttons on the dash. A horn chirp or flashing lights usually confirms each sensor has been registered.

OBD. This method requires a compatible TPMS tool. The tool reads each sensor, then connects to the vehicle’s OBD port to write the new IDs directly into its computer. This is the most common method in tire shops.

Automatic. Despite the name, it still takes some effort. The vehicle has to be driven without stopping, for a set amount of time, above a minimum speed. Once those conditions are met, the system picks up the new sensors on its own.

Some vehicles combine methods, for example an OBD relearn followed by a short drive. A few also need an extra step or a specific tool. That’s normal, not a sign that something went wrong.

How to find your vehicle’s procedure

Your owner’s manual usually describes the relearn method in the tire or TPMS section.

Your dealership can also confirm the procedure from your VIN. Note that many dealer tools are built for original (OE) sensors. They can’t relearn aftermarket sensors, even pre-programmed ones.

Most tire shops and garages now carry a universal TPMS tool, since aftermarket sensors have become common across Canada.

Buying your own tool is an option. Just check that it supports your exact make, model and year before ordering.

TPMS sensors from Blackcircles.ca

At Blackcircles.ca, we use aftermarket TPMS sensors. Our technicians program them for your vehicle using the information provided in your order.

Your sensors therefore arrive already programmed. As with any universal sensor, a relearn is still required once the wheels are installed.

Cloning, so you don’t need a relearn every season

To make things easier, we also offer to clone your original sensors. A cloned sensor takes on the ID of your original sensor. On most vehicles, it then works exactly like the original, with no relearn needed each time you swap wheels for the season.

A programming tool available to you

We provide a TPMS programming tool. It’s loaned against a $200 deposit plus taxes, and a flat $40 fee covers round-trip shipping. A return label is provided. Once we receive the tool, we refund your deposit, minus the shipping fee.

Detailed cloning instructions are sent to you by email. Our customer service team is here to help if needed.
