DESCRIPTION The forward recognition camera receives necessary information from the millimeter wave radar sensor assembly.
When
the forward recognition camera judges that a millimeter wave radar
sensor assembly which is not compatible with the vehicle has been
installed, DTC C1A0A is stored. |
DTC No. | Detection Item |
DTC Detection Condition | Trouble Area | |
C1A0A | Front Radar Sensor Region Code Mismatch |
After
the ignition switch is turned to ON for 3 seconds or more, the forward
recognition camera detects that a millimeter wave radar sensor assembly
which is not compatible with the vehicle is installed for 5 seconds or
more. |
- Millimeter wave radar sensor assembly
- Forward recognition camera
| CAUTION / NOTICE / HINT
NOTICE:
- 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.
