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

DIMO gives developers API access to Toyota Corolla vehicle data. Model years 2008 and newer connect with a DIMO device (DIMO LTE R1 or AutoPi). Headline signals include odometer, vehicle speed and vehicle ignition status.

DIMO gives developers API access to vehicle-state data: diagnostics, fault codes, battery and fuel health, odometer, and maintenance signals. For the Toyota Corolla, data comes through a DIMO device, with tested coverage for 2008 and newer model years. The record lists the DIMO LTE R1 and AutoPi devices for this model. Vehicle owners consent to and control sharing, so builders get data with clear provenance.

Signals by connection type

No factory connectivity?

Toyota Corolla 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.

Build it

Query the latest Toyota Corolla 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 Corolla signals
const data = await dimo.telemetry.query({
  ...vehicleJwt,
  query: `
    query {
      signalsLatest(tokenId: ${tokenId}) {
      powertrainTransmissionTravelledDistance {
        value
        timestamp
      }
      speed {
        value
        timestamp
      }
      isIgnitionOn {
        value
        timestamp
      }
      }
    }`,
});
console.log(JSON.stringify(data, null, 2));
