GMC Sierra 1500 vehicle data API: signals, model years and connection options

DIMO gives developers API access to GMC Sierra 1500 vehicle data. Model years 2009 and newer connect with a DIMO device (DIMO LTE R1 or AutoPi). Headline signals include odometer, fuel percentage and current charge level.

DIMO gives developers API access to vehicle-state data: diagnostics, fault codes, battery and fuel health, odometer, and maintenance signals. The GMC Sierra 1500 connects through a DIMO device, for model years 2009 and newer, and this coverage is tested rather than expected. Once the owner consents to sharing, your application reads the data through the DIMO APIs. DIMO adds vehicle-state depth on top of GPS tracking; it doesn't replace it.

Signals by connection type

No factory connectivity?

GMC Sierra 1500 model years 2009 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 GMC Sierra 1500 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 GMC Sierra 1500 signals
const data = await dimo.telemetry.query({
  ...vehicleJwt,
  query: `
    query {
      signalsLatest(tokenId: ${tokenId}) {
      powertrainTransmissionTravelledDistance {
        value
        timestamp
      }
      powertrainFuelSystemRelativeLevel {
        value
        timestamp
      }
      powertrainTractionBatteryStateOfChargeCurrent {
        value
        timestamp
      }
      }
    }`,
});
console.log(JSON.stringify(data, null, 2));
