Jeep Grand Cherokee vehicle data API: signals, model years and connection options

DIMO gives developers API access to Jeep Grand Cherokee vehicle data. Model years 2012 and newer connect with a DIMO device (DIMO LTE R1 or AutoPi). Headline signals include odometer, fuel percentage and vehicle speed.

DIMO offers a Jeep Grand Cherokee vehicle data API for 2012 and newer model years, delivered through a DIMO device. DIMO gives developers API access to vehicle-state data: diagnostics, fault codes, battery and fuel health, odometer, and maintenance signals. Coverage for this model is tested, not just expected. The record lists it as a combustion-engine vehicle with global regional coverage.

Signals by connection type

No factory connectivity?

Jeep Grand Cherokee model years 2012 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
• New diagnostic trouble code

Build it

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