GPS for leasing and operating lease: the OBD case

If the vehicles are not yours —leasing, operating lease, car sharing, mixed fleet without an installer available— you cannot go cutting cables. The OBD II port is the answer. This page explains when it works, when it does not, and why the FMC003 is the right device.

Why OBD is the choice for leasing and operating lease

The leasing contract forbids modifying the vehicle. Cutting the ignition cable, splicing a relay into the fuel pump or pulling permanent power from the dashboard CAN is off-limits. When you return the car, it has to be as it left the factory.

The OBD II connector (mandatory on every petrol car since 2001 and diesel since 2004 in the EU) gives you three things in one socket: permanent power, ignition and CAN bus. Plug in, remove on return, no trace left.

FMC003: real OBD plug & play

The FMC003 is the Teltonika OBD II 4G device. Plug & play in the literal sense: plug it into the dashboard OBD port, the car powers it, the tracker authenticates against the ECU and starts reporting.

Features relevant for leasing:

  • Compact size: does not protrude from the OBD slot on most models. On cars where it does, a discreet OBD extender under the dashboard.
  • 4G LTE Cat 1 with 2G fallback.
  • Multi-constellation GNSS (GPS + Galileo + GLONASS).
  • Internal accelerometer: detects motion even with the car off, for crash detection and eco-driving events.
  • Internal backup battery: if someone unplugs the tracker, the FMC003 sends an alert before powering down.
  • Fleet-wide management via FOTA Web.

What data OBD gives you

Over standard OBD II (Mode 01 and following) the FMC003 reads:

  • Vehicle speed (not GNSS, but the real speedometer).
  • Engine RPM.
  • Engine load as a percentage.
  • Coolant temperature.
  • Instantaneous fuel consumption (compatible vehicles).
  • DTC fault codes.
  • MIL status (fault indicator).
  • Vehicle battery voltage.

On vehicles with manufacturer OBD extensions (some Volkswagen Group, BMW, PSA) there are extra parameters like kilometres to next service, AdBlue, tire pressure. They are read with specific configurator profiles.

What OBD does NOT give you

OBD II is a diagnostic protocol, not a control one. That means:

  • You cannot cut the engine. There are no digital outputs. If you need anti-theft immobilisation, OBD will not do.
  • You cannot read iButton or RFID. If you need driver identification in a corporate fleet, OBD falls short.
  • It does not have RS485 or a port for LLS probes. For refrigerated delivery or external fuel measurement, it is not the right piece.
  • Some vehicles cut OBD power with the car off. In those cases the tracker sleeps between starts (the FMC003 uses its internal battery to send the last status before going to sleep).

When OBD is not enough: alternatives

  • You need engine cut-off: wired FMC920, professional install. Some leasing companies accept it if the installer can prove the brand and leaves no trace.
  • You need tachograph and J1939: the vehicle is not a typical leased car, it is a heavy commercial. Move to the FMC650.
  • You need full CAN bus reading without touching the car: devices with non-intrusive CAN-CONTROL (inductive reading), but that is already a professional install, not plug & play.

Operations for a leasing or operating lease fleet

If you manage more than 30 vehicles on lease, the typical FMC003 flow:

  1. Vehicle handover: driver picks up at the dealership. The manager plugs the FMC003 into the OBD in 60 seconds.
  2. Remote provisioning: the device appears on the platform with its IMEI, driver and licence plate are assigned from the desktop.
  3. Contract life management: kilometre reporting to avoid excess-mileage penalties (leasing contracts have a km/year limit), eco-driving to reduce accident rates, geofence alerts if the car leaves an agreed territorial scope.
  4. Return: you unplug the FMC003, keep it for the next vehicle in the batch. No marks on the wiring, no trace in the ECU.

The same device rotates across vehicles during the working life of your fleet. That is the real economics of OBD vs. wired install.

Frequently asked questions

Does the FMC003 work in every car?

On every car with standard OBD II (EU petrol since 2001, diesel since 2004) and on most modern vans. For heavy vehicles with J1939 you need an adapter or to move to the FMC650.

Will the fault light come on when I plug in the FMC003?

No. The FMC003 acts as a passive diagnostic tool: it only reads, it does not write parameters that trigger the MIL. It is certified not to affect vehicle operation.

Can the leasing company or the dealer detect it?

At a glance, yes: it is plugged into the OBD. It is not a hidden device. But it leaves no trace in the ECU or wiring, so once unplugged there is no record. If the contract requires express authorisation, check with your leasing provider.

What if someone unplugs it with bad intent?

The FMC003 has an internal backup battery. Before powering down it sends a disconnect alert with the last position. You can also place the OBD behind a screwed cover if the customer allows it.

How much does the FMC003 cost in an order of 30 units?

There is volume tiering from 10 units and further improvement at 50/100. Request a proposal at info@trackiber.es stating volume and destination platform.

Can I return the FMC003 if I change my mind?

No. Trackiber sells to professionals (B2B), so the 14-day consumer right of withdrawal does not apply. If for a reasonable commercial reason you need to return an unopened unit, we assess it case by case: request within 14 days of receipt, product unused, unconfigured and with intact seals, return shipping at the customer's expense and a reconditioning charge may apply (up to 20%). Full detail in the return policy. If the device arrives defective or with a Trackiber logistics error, we pay the return shipping.
