If there wasn’t already enough evidence that a Tesla is essentially an iPhone on four wheels, you can now check out the battery health on any of the company’s cars — or at least Tesla service personnel can.
Tesla has updated the “Service Mode” for its electric vehicles (EVs) in software version 2022.36.2. to now include a new tab for the high voltage battery (via Reddit).
Service Mode is a debugging utility designed to help service personnel diagnose problems on a Tesla EV. Even though the code to access Service Mode is just “service,” the feature is geo-locked and typically can’t be triggered unless the car is physically at a service center.
The new Battery tab details the car’s HV battery system and also includes a Battery Health percentage. What’s more, there’s also a Battery Health Test that can be run to gauge the health of the high voltage Battery.
According to the warning that pops up when attempting to run it, the Battery Health Test can only be initiated when the car is at less than 50% charge and is plugged into a level 2 charger. The test can take up to 24 hours, during which the Tesla will discharge and then fully recharge its high voltage battery.

Tesla last month added additional information to Service Mode so that it also displayed the status of the vehicle’s GPS systems, infotainment ECU, Autopilot ECU, radar, and more. Before that, Tesla redesigned the Service Mode interface to show more detailed information.
