What our car electronic diagnostics covers
Electronic diagnostics lets us pinpoint exactly where a fault comes from before we touch your car.
Electronic system checks
Sensors, wiring and engine-related electronic components are checked to locate the source of a malfunction.
Diagnosis before preparation
Before an engine map or a preparation, we make sure the vehicle's electronics are healthy.

How we carry out car electronic diagnostics
An engine warning light coming on, a limp mode kicking in or unusual behaviour on the road: on a modern sports car, almost everything runs through the electronics. Car electronic diagnostics means querying the vehicle's ECUs to read the stored faults, then checking the sensors and systems involved. At Bernis Factory, this step exists to understand the real source of a problem before starting any repair, rather than replacing parts at random.
This rigour comes from our core trade, bespoke engine preparation. Our engine engineer works every day on the engine and gearbox ECUs of high-end sports cars, mapping them case by case. This in-depth knowledge of on-board electronics lets us read a diagnosis with perspective, tell a genuine fault from a secondary alert, and point you towards the most relevant action for your vehicle.
Le diagnostic électronique est aussi un préalable idéal pour passer le contrôle sereinement — nos techniciens s'assurent que votre véhicule ne présente aucun défaut susceptible d'entraîner un refus.

Frequently asked questions about electronic diagnostics
What is car electronic diagnostics?
It is the operation of querying your vehicle's ECUs to read the stored faults, then checking the sensors and systems involved. The goal is to identify the source of a malfunction before any repair.
Which vehicles do you carry out this diagnosis on?
We work on the high-end sports cars we prepare and maintain every day, such as Ferrari, BMW M, Mercedes AMG, Porsche or Nissan GT-R, for both road and track use.
Is the diagnosis useful before an engine preparation?
Yes. Before a map or a preparation, we check that the vehicle's electronics are healthy. This avoids working on a base with an unidentified fault and secures the rest of the work.
Do you give a price for electronic diagnostics?
The need depends on the vehicle and the symptom observed. The simplest step is to describe the situation and contact us directly so we can work out the way forward together.
Do I need to be near the Paul Ricard circuit to come?
Our workshop is in Signes, 700 metres from the Paul Ricard circuit, at Le Castelet. We welcome both local owners and passing enthusiasts for a diagnosis before or after a track session.
Electronic diagnostics designed for sports cars
Finding a workshop able to carry out serious car electronic diagnostics on a high-end sports car is not easy. Many simply read a fault code and replace the suggested part, without looking for the real cause. Bernis Factory approaches diagnostics differently, with the eye of a workshop that prepares and maps engines case by case and knows these cars' on-board electronics in depth.
Located in Signes, 700 metres from the Paul Ricard circuit, our workshop links three trades: maintaining, preparing and restoring high-end sports cars. Electronic diagnostics fits into this logic: it secures a service, prepares an engine map or validates a vehicle's condition before a track day. It is a concrete starting point for understanding your car before working on it.
