LANE DEPARTURE ALERT SYSTEM, Diagnostic DTC:C1AA8

DTC Code DTC Name
C1AA8 Front Camera Module Incorrect Axial Gap

DESCRIPTION

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

DTC Code DTC Detection Condition Trouble Area
C1AA8 When the system is operating, a misaligned axis in 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. If an ECU 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 output.

  • When the pre-crash safety city sensor is replaced with a new one or the windshield glass is replaced or removed, camera beam axis learning must be performed.

PROCEDURE


  1. CHECK FOR DTC
