Toyota RAV4 EV

Vehicle Type: TYR4

At present, support for the 2012-2014 Toyota RAV4 EV in OVMS is experimental and under development. This vehicle type can be used by early adopters, as long as you understand the limitations. The current release only shows information from the Tesla CAN bus, not the Toyota CAN bus and is read-only.

The Tesla CAN bus already had decodes available, so those were implemented already. The primary focus going forward will be decoding the Toyota CAN bus to replicate SafetyConnect connected features like Remote Climate before the 3G shutdown ends that manufacturer provided functionality.
