What should you do if the Blue and Me display of your Fiat 500 is blinking?
Blinking of the dashboard or the Blue and Me display is a common issue on the Fiat 500. This symptom often indicates a PROXI misalignment or a failure of the Blue and Me module, which manages Bluetooth connectivity, USB functions, and voice commands.
Reparlab explains how to identify the cause, make the right diagnosis, and permanently repair the Blue and Me module.
The Blue and Me Module: Function and Failure Symptoms
The Blue and Me system, developed jointly by Fiat and Microsoft, is the central telecommunication and infotainment module of FCA group vehicles, including the Fiat 500.
It manages Bluetooth connectivity, the USB port, and voice commands, while also ensuring communication between the vehicle’s various control units through the CAN network.
Installed inside the cabin, this module is exposed to temperature variations and vibrations, which can eventually cause electronic failures or a PROXI misalignment.
The most common manufacturer references include 51989250, 52013328, and LTLJVCR65.
Typical Signs of an Internal Failure
Le dysfonctionnement du boîtier Blue and Me génère une série de symptômes très caractéristiques que vous devez maîtriser pour un diagnostic rapide :
Blinking of the Odometer
This is the most common symptom. It indicates a communication error (PROXI Alignment) on the CAN network, as the Body Computer is unable to verify the data from the Blue and Me module.
Bluetooth Malfunction
- No Bluetooth connection or persistent difficulty pairing new phones.
- Unexpected disconnections or distorted sound in hands-free mode.
Steering Wheel Controls Not Working and Battery Drain
The control buttons dedicated to phone or media no longer respond.
- In some cases, the module remains permanently active, causing significant parasitic power consumption when the vehicle is off.
Specific Fault Codes
Échec du démarrage (parfois lié à la température du module TCU)
A professional diagnostic tool is essential to confirm the failure of the unit. The codes most commonly associated with a Blue&Me failure are:
Here is a rewording of the error codes, keeping the main information unchanged:
- B1067-67: Communication problem with the control unit responsible for the vehicle’s dynamic control (e.g., ESP/ESC).
- B1074-4A: Configuration or PROXI alignment error (a process that synchronizes the electronic modules in the vehicle).
- U1733-87: Communication failure with the control module of the immobilizer system.
- U1707: Communication fault with the control module of the electric parking brake (EPB).
When Should You Send the Module to an Expert?
As soon as the electronic diagnosis reveals a communication fault (U1733) or a PROXI alignment issue that cannot be resolved through a simple software procedure, electronic repair of the unit becomes necessary.
Technical Requirement: The Unit Must Remain Sealed
Choose Repair
Failures of the Blue and Me module, often linked to internal electronic issues or PROXI misalignments, may appear as dashboard blinking or loss of Bluetooth and USB connectivity. An accurate diagnosis that takes into account the CAN network and the associated fault codes is essential to confirm the origin of the failure.
When faced with this type of failure, the specialized repair service offered by Reparlab by Faurecia Clarion provides an expert, durable, and cost-effective solution. By keeping the original unit intact, you benefit from Reparlab’s R&D expertise and certified repair processes, ensuring the reliability and longevity of the repaired Blue&Me module.
Have questions? Find your answers here!
What should you do if the customer has already tried disconnecting the battery?
If the issue persists, it is a hardware problem, and disconnecting the battery was not enough to fix the electronic fault. A professional inspection of the module is the only solution.
Is the repair more reliable than a standard exchange?
Yes. We correct the structural weakness of the component, giving it a reliable second life while helping reduce electronic waste.
How does Blue&Me work?
It is the convergence module that acts as a gateway between the vehicle’s CAN network and its multimedia/connectivity functions (Bluetooth, USB, voice commands).
What is the Blue and Me system in the Fiat 500?
It is the communication and entertainment system (hands-free, USB playback) developed by Fiat and Microsoft, whose failure causes Bluetooth and USB issues as well as the odometer blinking problem.
