Caution / Notice / Hint

WARNING: This page is about a different variant/trim than selected.
NOTE:
  • When DTC B1441, B1442, B1443 (w/o Driver Seat Centralized Control) and B1446 (w/ Driver Seat Centralized Control) are output at the same time, the No. 1 air conditioning radiator damper servo sub-assembly is malfunctioning.
  • Confirm that no mechanical problem is present because this diagnostic code can be output when either a damper link or the damper is mechanically locked.
  • When installing the servo motor, make sure to install it correctly.
  • When the servo motor is replaced, be sure to perform servo motor initialization.

    Refer to INITIALIZATION [02/2019 - ]
