DESCRIPTION The forward
recognition camera receives vehicle speed tolerance signals from the
combination meter assembly. If the combination meter assembly detects a
vehicle speed tolerance malfunction signal, it informs the forward
recognition camera via CAN communication, and DTC C1AA2 is stored. |
DTC No. | Detection Item |
DTC Detection Condition | Trouble Area | |
C1AA2 | Vehicle Speed Tolerance Malfunction |
When
the vehicle is being driven at a speed of 5 km/h (3 mph) or more 3
seconds after the ignition switch is turned to ON, a signal from the
combination meter assembly indicating an abnormal vehicle speed
tolerance is detected by the forward recognition camera for 50 seconds
or more. |
- Meter/gauge system
- Combination meter 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 learning.
