Dodge Grand Caravan vehicle data API: signals, model years and connection options

DIMO gives developers API access to Dodge Grand Caravan vehicle data. Model years 2011 and newer connect with a DIMO device (DIMO LTE R1 or AutoPi). Headline signals include fuel percentage, vehicle speed and engine rpm.

DIMO provides a vehicle data API for the Dodge Grand Caravan through a DIMO device, covering model years 2011 and newer; coverage for this vehicle has been tested. DIMO gives developers API access to vehicle-state data: diagnostics, fault codes, battery and fuel health, odometer, and maintenance signals. Vehicle owners consent to and control sharing, so builders get data with clear provenance. Exchange your Developer JWT for a Vehicle JWT, then query the Telemetry API with GraphQL.

Signals by connection type

No factory connectivity?

Dodge Grand Caravan model years 2011 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
• New diagnostic trouble code
• Harsh braking

Build it

Query the latest Dodge Grand Caravan 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 Dodge Grand Caravan signals
const data = await dimo.telemetry.query({
  ...vehicleJwt,
  query: `
    query {
      signalsLatest(tokenId: ${tokenId}) {
      powertrainFuelSystemRelativeLevel {
        value
        timestamp
      }
      speed {
        value
        timestamp
      }
      powertrainCombustionEngineSpeed {
        value
        timestamp
      }
      }
    }`,
});
console.log(JSON.stringify(data, null, 2));
