Start beneath the steering wheel and around the fuse cover. Look for a trapezoidal 16-pin connector, switch the ignition off and never force a trim panel.
Recognise the correct connector
An OBD2 connector is trapezoidal and contains two rows for up to 16 pins. Its colour may vary. Do not confuse it with USB, a 12 V socket or an accessory connector.
A small removable cover may hide the port, but routine connection should not require tools or dismantling fixed trim.
Check the most common locations
Use your phone light and inspect the driver’s footwell before looking elsewhere.
- Under the steering column or above the pedals.
- Behind the driver-side fuse cover.
- Along the lower dashboard or centre console.
- Near a small storage compartment or ashtray.
If a panel is screwed in place or resists strongly, stop. The diagnostic connector should be accessible without damage.
Connect OBDPhone® safely
Park securely, apply the handbrake and switch the ignition off. Align the plug and insert it straight. If normal pressure is not enough, check the orientation.
Make sure the adapter cannot obstruct the pedals. After the scan, remove it if its position could interfere with driving.
A port does not guarantee compatibility
Some vehicles have the physical connector without complete standard engine access. Model year, fuel type and generation still matter, especially for older, hybrid, electric and recent commercial vehicles.
