(If equipped) For vehicle equipped with AVH and Auto Start stop: For vehicle equipped with AVH (only): 2 Air conditioner control interface is changed to that of 23MY. Current ( -22MY) screen transition: 23MY screen transition: Bulletin Number: 15-301-22R; Revised: 05/22/23 Page 30 of 39 Continued… Symptoms Addressed By Update #2: Number Symptoms to be Improved: 1 The CID stays black following reboot. Reset doesn’t always recover this condition. 2 The CID stays black or very dark even after the ignition switch is turned on due to back light malfunction. 3 When using CarPlay, the screen goes to black and/or CID restarts. It occurs when the CID processor falls under irregularly high load conditions. 4 The CID restarts about 3 minutes after turning on the Ignition Switch. It occurs when the CID processor falls under irregularly high load conditions. 5 System reboot due to application failure. Software robustness has been imporved to prevent CID and CCU from resetting whenever its individual function fails. 6 When the vehicle comes to a place on a highway where there are multiple exits with combinations of alphabets and numbers (see example below) the CID cannot process the information correctly for turn-byturn navigation and restarts. Example: 7 CID restarts when Navigation system is re-routing the route crossing the border of the states. When the customer veered off navigated route and the re-routed route includes the roads across the boarder of states, the calculation is not properly processed and the CID restarts. 8 CID restarts, while it is connected to Wi-Fi. It occurs when Wi-Fi signal includes illegible data. 9 CID restarts after the ignition switch is turned off and on again before the CID shuts off. 10 No functional response on touch screen in Radio mode even though the touch sound and visual reaction are confirmed. 11 Reprogramming process takes extensive time (40 minutes or more.) After the ignition switch is turned off and on again, the combination meter display mode changes itself and shows the ECO gauge (Current fuel consumption/Driving range on remaining fuel.) Both attribute to processing errors in CCU.
