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

DIMO gives developers API access to Toyota Tacoma vehicle data. Model years 2010 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 Tacoma, 2010 and newer model years connect through a DIMO device, and this coverage is tested rather than expected. Once a vehicle is shared with you, you can query it through the Telemetry API with a Vehicle JWT. Vehicle owners consent to and control sharing, so builders get data with clear provenance.

Signals by connection type

No factory connectivity?

Toyota Tacoma model years 2010 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
• Harsh braking

Build it

Query the latest Toyota Tacoma 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 Tacoma 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));
