Potential defects and errors

A multimedia Bluetooth control unit, such as Fiat's Blue&Me, is a thoroughly complex electronic assembly. Just like a conventional computer, the unit contains a power supply, a processing unit, random-access memory, a hard drive and a Bluetooth module. However, unlike a PC, these are not plugged together in modules with cables, but are soldered directly onto a circuit board.

Possible defects of the telematics system

A faulty multimedia control unit can manifest through various symptoms. In the event of a fault, a Bluetooth connection cannot be established, the USB port does not work, the hands-free function is disrupted, the odometer flashes, the vehicle battery is discharged, and the multimedia control unit can no longer be diagnosed.

Common fault codes

There are many possible fault codes, but not all of them have to be stored. Usually, just one is enough to assume that the multimedia control unit is faulty.

B1005 – Diagnostic sensor unit
B1039 – Microphone input short circuit
B10AA – Proxy configuration check
P0022 – Control unit convergence node
U1602 – CAN bus line fault
U1701 – Communication error with body computer
U1707 – Control module info-telematics / Convergence control module
U1733 – Communication with telematics system

Our Blue&Me repair

At the Repair of the multimedia control unitand the individual parts must be checked and their interaction tested. The most frequent problem is the „hard drive“. This consists of a component called NAND. The NAND is an electronic memory chip that begins to forget or damage data over the course of its lifespan. During module repair, this chip is read using a special process and the data is recovered.

Blue&Me and its function

The presentation of Blue&Me was in 2006 and it was fitted in many models from Abarth, Alfa Romeo, Chrysler, Dodge, Fiat and also Lancia until 2016. The infotainment system is based on „Windows Mobile for Automotive“ and performs a range of functions. Among other things, it controls the Bluetooth hands-free system, the voice control and manages the vehicle's USB interface. The internal Fiat designation for the multimedia control unit is Lauberhorn.

The ECU test

To ensure that everything works perfectly again after the Blue&Me multimedia control unit has been repaired, we carry out a functional test on the workbench. During this test, the multimedia control unit is checked for CAN communication, audio input and output, and Bluetooth functionality.

Software update to the latest version

Following successful repair and final functional testing, we also perform an update to ensure the software is up to date. This ensures that the control unit can continue to operate reliably for a long time to come.

Programming after repair

Usually, the teach-in parameters can be restored. This means the repaired control unit is „Plug and play“Should the parameters not be able to be restored, the repaired Blue&Me must be programmed to the vehicle. To do this, a so-called „proxy alignment“ must be carried out using a suitable diagnostic tester. Should this be the case with your control unit, we will inform you beforehand. As long as the Blue&Me has not been programmed, the mileage on the instrument cluster will flash.
