The forward recognition camera controls the flow of current to the forward recognition with heater hood sub-assembly.
If the forward recognition camera detects a malfunction in the forward recognition with heater hood sub-assembly circuit, it will store this DTC.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | DTC Output from | Priority |
|---|---|---|---|---|---|
| C1AAE00 | Front Recognition Camera Heater Malfunction | Either of the following conditions is met after 10 seconds have elapsed since the ignition switch was turned to ON:
·
Short to +B detected in the forward recognition with heater hood sub-assembly circuit for 1 second or more cumulatively (1 trip detection logic) ·
Open or short to ground detected in the forward recognition with heater hood sub-assembly circuit for 5 seconds or more (1 trip detection logic) |

Inspect the fuses for circuits related to this system before performing the following procedure.
When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle. As a result, a DTC may be stored.
When the forward recognition camera is replaced with a new one, make sure to perform beam axis adjustment for the forward recognition camera and clear the vehicle control history for each system.
Forward recognition camera axis alignment can be performed by using either One Time Recognition, Sequential Recognition or Driving Adjustment.
