Scheme 296
If the power switch is turned on (IG) after replacing the No. 1 night view ECU or night view camera without performing night view camera adjustment, a DTC is stored. When night view camera adjustment is completed successfully, the DTC is cleared automatically.
HINT
While DTCs are stored, the night view system does not operate and a warning message is displayed on the accessory meter assembly.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| B281A | The power switch is turned on (IG) without performing night view camera adjustment. | Night view camera adjustment No. 1 night view ECU |
The No. 1 night view ECU monitors the power supplied to the night view camera. This DTC is stored if a power supply malfunction is detected.
HINT
While DTCs are stored, the night view system does not operate and a warning message is displayed on the accessory meter assembly.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| B281B | When the night view system is operating, the voltage at the CCD+ terminal of the No. 1 night view ECU is not between 5.7 and 6.5 V for 1 second or more. | Harness or connector Night view camera assembly No. 1 night view ECU |
Scheme 297
The No. 1 night view ECU monitors the synchronization signal of the night view camera. This DTC is stored when a synchronization signal malfunction is detected.
HINT
While DTCs are stored, the night view system does not operate and a warning message is displayed on the accessory meter assembly.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| B281C | There is an NTSC signal synchronization problem. | Harness or connector Night view camera assembly No. 1 night view ECU |
Scheme 298
The No. 1 night view ECU receives headlight dimmer switch signals from the main body ECU via CAN communication.
This DTC is stored when an abnormal combination of headlight dimmer switch signals are detected.
HINT
While DTCs are stored, the night view system does not operate and a warning message is displayed on the accessory meter assembly.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2821 | The No. 1 night view ECU detects an abnormal combination of headlight dimmer switch signals. | CAN communication system Lighting system No. 1 night view ECU |
Scheme 299
The No. 1 night view ECU communicates with the driving support ECU via CAN communication. This DTC is stored when a malfunction in the communication with the driving support ECU is detected.
HINT
While DTCs are stored, the night view system does not operate and a warning message is displayed on the accessory meter assembly.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2824 | The driving support ECU cannot receive CAN communication signals normally. | CAN communication system No. 1 night view ECU |
Scheme 300
The No. 1 night view ECU receives automatic light control signals from the main body ECU via CAN communication. This DTC is stored when an automatic light control signal malfunction is detected.
HINT
While DTCs are stored, the night view system does not operate and a warning message is displayed on the accessory meter assembly.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2825 | The No. 1 night view ECU continuously receives abnormal automatic light control information for 3 seconds. | CAN communication system Lighting system No. 1 night view ECU |
Scheme 301
If the power switch is turned on (IG) after replacing the No. 1 night view ECU without performing night view camera adjustment, or the No. 1 night view ECU determines that there is a mismatch in the destination or headlight type information, a DTC is stored. When night view camera adjustment is completed successfully, the DTC is cleared automatically.
HINT
While DTCs are stored, the night view system does not operate and a warning message is displayed on the accessory meter assembly.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2827 | The No. 1 night view ECU detects a malfunction in the initial settings when the power switch is turned on (IG). | Night view camera adjustment No. 1 night view ECU |
The No. 1 night view ECU communicates with the driving support ECU via CAN communication. This DTC is stored when a malfunction in the communication with the driving support ECU is detected.
HINT
While DTCs are stored, the night view system does not operate and a warning message is displayed on the accessory meter assembly.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| U1104 | There is a malfunction in the communication with the driving support ECU. | CAN communication system |
Scheme 302
When the No. 1 night view ECU receives the switch signal from the night view switch, the ECU outputs a night view display request signal to the multi-media module receiver assembly.
Scheme 303
The No. 1 night view ECU receives the front image signal from the night view camera. Using the digital (GVIF) signal line, the image data is sent to the accessory meter assembly and the area in front of the vehicle is displayed for the driver (night view screen).
Scheme 304
The night view system includes the night view camera and near-infrared ray emitters. When these parts are damaged or dirty, when they do not operate properly, or when the beam axis of a near-infrared ray emitter is not properly adjusted, these symptoms may appear.
