The Blue&Me module fitted to your Fiat 500 plays a crucial role in enabling Bluetooth connectivity between your phone and the infotainment system, allowing hands-free calling and voice control. When your Blue&Me module experiences an internal malfunction, however, you will encounter the following diagnostic trouble code:

•    U1733-87 - Convergence telematics module missing message

U1733-87 Fault Code Explained

U1733-87 is a network communication fault that is stored in your Fiat 500’s BCM when the body control module, instrument cluster, or infotainment system cannot establish CAN communication with the Blue&Me module. This occurs when the Blue&Me unit develops an internal failure that prevents it from responding on the network. Under normal operation, the Blue&Me module communicates with the BCM via the vehicle’s low-speed CAN bus network.

The BCM expects regular status messages from multiple control units on the CAN bus. So, when it detects that the Blue&Me unit is no longer communicating across the network, it registers this loss of communication and causes the odometer to flash continuously on your Fiat 500’s instrument cluster, storing the fault code U1733-87.

Alongside these symptoms, you will often find that your battery is draining over time. Under normal operation, the Blue&Me unit is designed to enter a low-power sleep state once the ignition is switched off and the CAN bus becomes idle. However, when faulty, the Blue&Me module fails to shut down correctly and continues drawing current from the Fiat 500’s permanent battery supply, leading to excessive parasitic drain, in addition to the U1733-87 code.
