Vehicle data

Acura MDX vehicle data API: signals, model years and connection options

Get API keys →

DIMO gives developers API access to Acura MDX 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 gives developers API access to vehicle-state data: diagnostics, fault codes, battery and fuel health, odometer, and maintenance signals. The Acura MDX, an ICE vehicle, connects through a DIMO device for model years 2011 and newer, and this coverage has been tested. Once the owner shares the vehicle with your Developer License, you exchange a Vehicle JWT and read its signals through the Telemetry API with GraphQL.

No factory connectivity?

Acura MDX 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
  • Harsh braking

Build it

Query the latest Acura MDX 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 Acura MDX 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));

FAQ

Can I read fuel level remotely on an Acura MDX?

Yes, through a DIMO device. The record lists Fuel Percentage (powertrainFuelSystemRelativeLevel) on both device entries, and the DIMO LTE R1 entry also lists Fuel Level in liters. Query it in the Telemetry API with a Vehicle JWT.

How do I track an Acura MDX with no connected services?

The record lists a DIMO device as the connection for this vehicle. After the owner shares the vehicle, exchange your Developer JWT for a Vehicle JWT and query signals in the Telemetry API. A query for availableSignals shows what a given vehicle reports.

How do I detect idling on an Acura MDX?

Idling is listed as an event for the DIMO device connection. Query the Telemetry API segments resource with the idling mechanism, which requires a DIMO device. It treats periods where engine RPM stays in the idle range as segments, and maxIdleRpm is configurable.

How do I verify Acura MDX mileage?

The DIMO LTE R1 device entry lists the odometer signal. To get a verifiable record, call the Attestation API odometer-statement endpoint (POST /v2/attestation/odometer-statement/:tokenId) with a Vehicle JWT, then retrieve the credential through the Telemetry API.

Which Acura MDX model years work with DIMO?

DIMO devices have been seen working on Acura MDX model years 2011 and newer. For older vehicles, contact DIMO for additional support.

Do I need hardware to get Acura MDX data?

Yes. DIMO lists no OEM cloud connection for the Acura MDX, so data comes from a DIMO device.
