ADVANCED DRIVER ASSISTANCE SYSTEM FRONT CAMERA SYSTEM(for NR Series Engine) C1AAE00 Front Recognition Camera Heater Malfunction
DESCRIPTION
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 |
|---|---|---|---|
| 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 ·
Open or short to ground detected in the forward recognition with heater hood sub-assembly circuit for 5 seconds or more |
·
Forward recognition with heater hood sub-assembly ·
Forward recognition camera ·
Wire harness or connector |
WIRING DIAGRAM
CAUTION / NOTICE / HINT
- NOTICE:
- ·
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.
·If the forward recognition camera has been replaced with a new one, be sure to perform forward recognition camera adjustment.
- HINT:
-
Forward recognition camera adjustment can be performed by using either One Time Recognition or Sequential Recognition.
