## NHTSA's summary

Aprilia RSV4 Factory 1100 E5\+ MY25, RS and Tuono 660 E5\+: PMP4 ECU calibration update The main improvements introduced with this calibration are: • Infotainment: irreversible blocking of the ECU in the event of pairing by the smartphone. The correct procedure is for the PMP4 to be paired by searching from the instrument cluster, not from the smartphone; • Infotainment: possible malfunctions of the intercom while listening to music or making calls; • Infotainment: resetting the call time count after approximately 4 minutes of conversation, • Infotainment :\(only RS\-Tuono 660 E5\+\): failure to connect the PMP4 to the instrument cluster. The above operation is to be understood as included in the normal maintenance activities to be carried out together with the pre\-delivery or the first appropriate visit to the workshop for vehicles in use.
