Toyota Prius vehicle data API: signals, model years and connection options

DIMO gives developers API access to Toyota Prius vehicle data. Model years 2008 and newer connect with a DIMO device (DIMO LTE R1 or AutoPi). Headline signals include vehicle speed, engine rpm and coolant temperature.

DIMO gives developers API access to vehicle-state data: diagnostics, fault codes, battery and fuel health, odometer, and maintenance signals. For the Toyota Prius, that data comes from a DIMO device, for model years 2008 and newer. Coverage for this model is tested rather than expected. You read the data through the Telemetry API with a Vehicle JWT, and the signals and events the Prius supports are listed below.

Signals by connection type

No factory connectivity?

Toyota Prius model years 2008 and newer have no OEM cloud connection listed. For these years, a DIMO device (DIMO LTE R1 or AutoPi) plugs into the OBD-II port and streams vehicle signals once the owner connects it and consents to sharing.

See the developer quickstart for how owners connect vehicles and grant access.

Events available

• Idling
• Refuel
• Recharge
• Harsh braking
• New diagnostic trouble code

Build it

Query the latest Toyota Prius signals with the DIMO TypeScript SDK. The vehicle owner must first share access with your app through DIMO Connect.

import { DIMO } from '@dimo-network/data-sdk';

const dimo = new DIMO('Production');
const tokenId = Number(process.env.DIMO_TOKEN_ID); // from DIMO Connect

const developerJwt = await dimo.auth.getDeveloperJwt({
  client_id: process.env.DIMO_CLIENT_ID,
  domain: process.env.DIMO_REDIRECT_URI,
  private_key: process.env.DIMO_API_KEY,
});
const vehicleJwt = await dimo.tokenexchange.getVehicleJwt({
  ...developerJwt,
  tokenId,
});

// Latest Toyota Prius signals
const data = await dimo.telemetry.query({
  ...vehicleJwt,
  query: `
    query {
      signalsLatest(tokenId: ${tokenId}) {
      speed {
        value
        timestamp
      }
      powertrainCombustionEngineSpeed {
        value
        timestamp
      }
      powertrainCombustionEngineECT {
        value
        timestamp
      }
      }
    }`,
});
console.log(JSON.stringify(data, null, 2));
