DTC Code DTC Name
C1AA8 Front Camera Module Incorrect Axial Gap

DESCRIPTION

If it is determined that the optical axis of the pre-crash safety city sensor has deviated, DTC C1AA8 is output.

DTC No.

Detection Item

DTC Detection Condition

Trouble Area

C1AA8

Front Camera Module Incorrect Axial Gap

When the system is operating, a misaligned axis of the pre-crash safety city sensor is detected.

  • Pre-crash safety city sensor

  • Windshield glass

CAUTION / NOTICE / HINT

Note:

  • When replacing the pre-crash safety city sensor, replace it with a new one and be sure to initialize the settings. If a pre-crash safety city sensor which was installed to another vehicle is used, the information stored in the pre-crash safety city sensor will not match the information from the vehicle and, as a result, a DTC may be stored.

  • If the pre-crash safety city sensor has been replaced, or the windshield glass has been replaced or removed/installed, be sure to perform Recognition Camera/Target Position Memory and Recognition Camera Axis Adjust.

  10. CLEAR DTCs

    1. Check for DTCs related to misalignment of the pre-crash safety city sensor.

      Tip:

      If only history DTCs are stored, they may have stored due to a temporarily condition such as overloading of the vehicle, and the system returned to normal when optical axis learning was performed.

    2. Clear the DTCs.
