Honda Fit Vehicle Data API: Signals & Model Years

DIMO gives developers API access to Honda Fit vehicle data. Model years 2009 and newer connect with a DIMO device (DIMO LTE R1). Headline signals include odometer, fuel percentage and vehicle speed.

DIMO provides a Honda Fit vehicle data API through a DIMO device, the DIMO LTE R1, for model years 2009 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. DIMO adds vehicle-state depth on top of GPS tracking; it doesn't replace it.

No factory connectivity?

Honda Fit model years 2009 and newer have no OEM cloud connection listed. For these years, a DIMO device (DIMO LTE R1) 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.

Harsh braking

Build it

Query the latest Honda Fit 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 Honda Fit 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));

FAQ

Can I read fuel level remotely on a Honda Fit?

Yes, through a DIMO device. The record lists Fuel Percentage (powertrainFuelSystemRelativeLevel) and Fuel Level in liters (powertrainFuelSystemAbsoluteLevel). Query them with a Vehicle JWT in the GraphQL Telemetry API.

How do I track a Honda Fit with no connected services?

Use a DIMO device, the DIMO LTE R1 for this vehicle. Once the owner shares the vehicle with your Developer License, exchange your Developer JWT for a Vehicle JWT through the Token Exchange API and query the Telemetry API.

How do I detect idling on a Honda Fit?

Query the Telemetry API segments resource with the idling detection mechanism, which requires a DIMO device. Idling segments are periods where engine RPM stays in the idle range, and you can set the upper bound with maxIdleRpm (default 1000).

How do I verify Honda Fit mileage?

With a DIMO device supplying the odometer signal, call the Attestation API odometer statement endpoint (POST /v2/attestation/odometer-statement/:tokenId). Then retrieve the resulting rawVC through the Telemetry API.

How do I detect harsh braking on a Honda Fit?

Harsh braking is a listed event for the DIMO device. Create a webhook through the Vehicle Triggers API using the events service and the behavior.harshBraking metric name, then subscribe the vehicle. Webhooks are currently in public beta.

Which Honda Fit model years work with DIMO?

DIMO devices have been seen working on Honda Fit model years 2009 and newer. For older vehicles, contact DIMO for additional support.

Do I need hardware to get Honda Fit data?

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