FRONT CAMERA SYSTEM(for Stereo Camera Type), Diagnostic DTC:C1AAE00

DTC Code DTC Name
C1AAE00 Front Recognition Camera Heater Malfunction

DESCRIPTION

The object recognition camera controls the flow of current to the internal heater.

If the object recognition camera detects a malfunction in the internal heater circuit, it will store this DTC.

DTC No. Detection Item DTC Detection Condition Trouble Area
C1AAE00 Front Recognition Camera Heater Malfunction

    Either of the following conditions is met after 3 seconds have elapsed since the power switch was turned on (IG):

  • Short to +B detected in the internal heater circuit for 1 second or more cumulatively

  • Open or short to ground detected in the internal heater circuit for 5 seconds or more

  • Object recognition camera

  • Harness or connector

CAUTION / NOTICE / HINT

Note


  • Inspect the fuses for circuits related to this system before performing the following procedure.

  • When replacing the object recognition camera, always replace it with a new one. If a object recognition camera which was installed to another vehicle is used, the information stored in the object recognition camera will not match the information from the vehicle. As a result, a DTC may be stored.

  • If the object recognition camera has been replaced with a new one, be sure to perform Object Recognition Camera Learning.
