NOTE: U119287 may be output before updating the version of the advanced drive software, as the versions of the software in the advanced drive ECU assembly and spatial information service ECU assembly do not match.

1. When the spatial information service ECU assembly is replaced, perform wired reprogramming.

   Refer to SOFTWARE UPDATE [11/2021 - ] 

1. When the spatial information service ECU assembly is removed and installed, or replaced, perform ECU installation angle learning.

   Refer to UTILITY [11/2021 - ]

1. After driving the vehicle with all conditions met for approximately 10 to 30 minutes cumulatively, the learning will be completed.
   1. Driving conditions
      • Drive at a vehicle speed of 40 km/h or higher.
      • Steer the vehicle straight without drifting or wobbling, and avoid sudden acceleration or deceleration.
      NOTE:

      • When performing the vehicle speed learning, obey all applicable traffic laws.
      • Select a road where the vehicle speed learning can be carried out safely.

      HINT: 

      • Vehicle speed learning can be completed by driving under driving conditions for 10 minutes continuously or for a total of 10 minutes intermittently.
      • When making frequent accelerations and decelerations, etc., which may cause learning to take a long time.
2. Using the GTS, confirm that the vehicle speed learning has been completed.
