This bulletin applies to 2017-2018 Alfa Romeo Giulia vehicles. Customers may experience a MIL on. The technician may find DTC U0103-00 (lost communication with gear shift module A) stored.
The customer may also note that the gear selector lever icons are blinking or turn off while the engine is running. The warning “Automatic Transmission Failure” appears in the instrument cluster.
The fix involves reprogramming the ESM (electronic shift module) with the latest software. Install a battery charger to maintain battery voltage between 13.2 and 13.5 volts during the flash process.
