IVMS Communication Diagnosis

  NOTE: Sleep is a power saving function when a vehicle is stationary (all BCM related electrical equipment: OFF, and the timer: OFF).
• The function also stores the communication malfunction records and inactive communication records, and displays the data on the CONSULT-II screen (Malfunction record diagnosis)
