DESCRIPTION

On the SIGNAL CHECK screen, it is possible to check if the signals sent to the parking assist ECU are normal (Click here).

Tip:

  • On the SIGNAL CHECK screen, "OK" (blue) is displayed for items with a normal inspection result or input state.

  • On the SIGNAL CHECK screen, "CHK" (red) is displayed for items with an abnormal inspection result or input state.

  • Displayed items may differ depending on vehicle specifications.

INSPECTION PROCEDURE

Note:

  • When "System initializing" is displayed on the navigation receiver assembly*1 or radio and display receiver assembly*2 after the battery cable is disconnected, 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 parking assist monitor system may be needed (Click here).
