INSPECTION PROCEDURE

Note


  • When "System initializing" is displayed on the parking assist ECU after the cable is disconnected from the negative (-) battery terminal, correct the steering angle neutral point Click here.

  • Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the side monitor system may be needed Click here.

PROCEDURE
