Resolving TCAM Failures in the Polestar 2: A Guide to the TCAM Reset Method

Polestar 2: An Affordable Electric Fastback Sedan with Potential Connectivity Issues and TCAM Failures Explained

Polestar, the electric vehicle arm of Volvo, has had a successful launch with their new all-electric fastback sedan, the Polestar 2. With a starting price of $48,400, the Polestar 2 offers a more affordable option than the $155,000 Polestar 1 hybrid. However, some owners have been experiencing connectivity failures that have led to TCAM (Telematics and Connectivity Antenna Module) failures and even rendered their cars inaccessible.

Understanding TCAM Failures in the Polestar 2: The Impact on Connectivity and Accessibility

The TCAM is the device that houses and controls the various connectivity radios in the Polestar 2, including data, GPS, Wi-Fi, Bluetooth, and key fob connection. When the TCAM fails, it can result in a lack of data and GPS connectivity, as well as rendering the car inaccessible and unable to drive.

To address the issue, Polestar has provided a TCAM reset method that has been reported to work for most users. The process is as follows:

1. Stop the car and make sure to be in park.
2. Hold the HOME button on the main screen until the infotainment system resets.
3. Immediately after the reboot, hold down the front window demist button for at least 15 seconds.

4. Wait patiently for a few seconds, and the SoS starts flashing.

5. Once the flashing stops, the 4G/LTE display will start changing, indicating a successful reset.

Alternative Solutions for TCAM Failures in the Polestar 2

However, this method has not worked for everyone, and in some cases, the TCAM battery needs to be disconnected to force a reset, which is a more involved process.

User mtg35 of the Polestar-forums provided a comprehensive write-up on the procedure. The process involves accessing the negative terminal of the 12V battery which is located under the panels in the front trunk (frunk). After that, disconnect the TCAM battery which is located in the rear side pillar behind the driver's rear door.

If you do not want to take apart your new EV, the next option is to schedule a service appointment with a Polestar Space. In some cases, the TCAM may recover on its own after waiting for some time.

In conclusion, the Polestar 2 is a great option for those looking for an electric vehicle at a more affordable price point than some of its competitors, like the Tesla Model 3. However, some owners have experienced TCAM failures which could lead to connectivity issues and render the car inaccessible. Polestar has provided a TCAM reset method that works for most users, but in some cases, a more involved process may be necessary. If you experience TCAM failures, it's best to schedule a service appointment with a Polestar Space.
