Possible defects and errors

A multimedia Bluetooth control unit, such as the Blue&Me from Fiat, is a quite complex electronic assembly. Like a conventional computer, the unit contains a power supply, a computing unit, a RAM, a hard disk and a Bluetooth module. However, unlike a PC, this is not all plugged together in modules with cables, but soldered directly onto a circuit board.

Possible defects of the telematics system

A defective Blue&Me can become noticeable through various symptoms. In the event of a fault, no Bluetooth connection can be established, the USB port is without function, the hands-free function is disturbed, the kilometre display flashes, the vehicle battery is discharged and the Blue&Me can no longer be diagnosed.

Common error codes

There are many possible error codes, but not all of them have to be stored. In most cases, one is sufficient to assume that the Blue&Me is defective.

B1005 - Diagnostic sensor unit
B1039 - Microphone Input Short Circuit
B10AA - Proxy configuration check
P0022 - Control unit convergence node
U1602 - Error CAN bus line

Our Blue&Me repair

At the Blue&Me Repair the individual parts must be checked and their interaction tested. The most common problem is the "hard disk". This consists of a component called NAND. The NAND is an electronic memory module which, in the course of its lifetime, begins to forget or damage data. During module repair, this component is read out with a special procedure and the data is restored.

The Blue&Me and its function

The Blue&Me was presented in 2006 and was installed in many Abarth, Alfa Romeo, Chrysler, Dodge, Fiat and Lancia models until 2016. The infotainment system is based on "Windows Mobile for Automotive" and fulfils a number of functions. Among other things, it controls the Bluetooth hands-free system, the voice control and manages the USB interface of the vehicle. The internal Fiat designation for the multimedia control unit is Lauberhorn.

The control unit test

To ensure that everything works 100%ig again after the Blue&Me repair, we carry out a function test on the table. The multimedia control unit is tested for CAN communication, audio input and output and Bluetooth function.

Software update to the latest status

After a successful repair and final function test, we carry out an update to ensure that the software is up to date. This ensures that the control unit can continue its service for a long time.

Teach-in after the repair

Usually, the teach-in parameters can be restored. Thus, the repaired control unit "Plug and Play". If the parameters cannot be restored, the repaired Blue&Me must be taught in the vehicle. To do this, a so-called "proxy alignment" must be carried out with a suitable tester. If this is the case with your control unit, we will inform you in advance. As long as the Blue&Me has not been tuned in, the KM reading in the speedometer will flash.
