Entire Image has Stripes or Streaks |
DESCRIPTION
- Screen with stripes occurs when a malfunction of the night view camera or the display occurs.
- Screen with streaks occurs by a malfunction of the night view camera or the display, and also by dirt on the windshield glass.
- Display power source (VGL, VDD VGH) from night view battery ECU is provided to the display via the night view ECU.

CHECK NIGHT VIEW CAMERA |
(a) Remove the over head junction (map light cover).
(b) disconnect the connector from the night view camera.
(c) Connect SST to the wire harness of the night view camera on the body side as shown in the illustration.
SST: 09991-00610
(d) Turn the ignition switch ON.
(e)
Switch to inspection mode
.
(f) Check the screen of the night view display.
OK:
3 levels of black-white shade intensity displayed.
(NG: Stripes still appear.)
| OK |

3. |
CHECK NIGHT VIEW ECU (VGL VOLTAGE) |
(a) Remove the combination meter assembly.
(b) Turn the ignition switch ON.
|
(c) Measure the voltage between terminal VGL of the night view ECU connector "C" and body ground.
(Terminals of ECU:
Standard voltage: -15 to -17 V HINT: Terminal voltage must meet the specified value within 20 seconds after ignition switch is ON. |
|
| NG |
|

|
4. |
CHECK NIGHT VIEW ECU (VDD VOLTAGE) |
(a) Turn the ignition switch ON.
|
(b) Measure the voltage between terminal VDD of the night view ECU connector "C" and body ground.
(Terminals of ECU:
Standard voltage: 4.75 to 5.25 V HINT: Terminal voltage must meet the specified value within 20 seconds after ignition switch is ON. |
|
| NG |
|
|
|
5. |
CHECK NIGHT VIEW ECU (VGH VOLTAGE) |
(a) Turn the ignition switch ON.
|
(b) Measure the voltage between terminal VGH of the night view ECU connector "C" and body ground.
(Terminals of ECU:
Standard voltage: 17.4 to 18.6 V HINT: Terminal voltage must meet the specified value within 20 seconds after ignition switch is ON. |
|
| OK |
|
|
|
6. |
CHECK WIRE HARNESS (NIGHT VIEW BATTERY ECU - NIGHT VIEW ECU) |
(a) Remove the wire harness between the night view battery ECU and the night view ECU.
(b) Measure the voltage between terminal VGL, VDD, and VGH of connector "D" and those of "B".
(Terminals of ECU:
)
Standard resistance:
Below 1 Ω
