WIRING DIAGRAM

INSPECTION PROCEDURE

PROCEDURE

(a) Check installation of the front bumper.

HINT:

The night view projector is installed in the front bumper.

The light axis of the night view projector should be normal if the front bumper is installed on the body properly.

OK:

No damage or deformation of the front bumper and the night view projector.

All repairs should be completed based on the standard value in the body repair manual.

HINT:

If objects are displayed too bright on the screen when the objects stand or exist within 100 m (328 ft.), the light axis of the night projector may not be at the correct angle.

INSPECT AND REPLACE FRONT BUMPER OR NIGHT VIEW PROJECTOR

OK

(a) Check the windshield glass in front of the night view camera.

OK:

Windshield glass is clean.

HINT:

Night view camera cleaning method .

NG

CLEAN WINDSHIELD GLASS (DIRT ON WINDSHIELD GLASS)

OK

OK

MISADJUSTMENT OF NIGHT VIEW SWITCH (RHEOSTAT FUNCTION)

NG

(a) Check if the display illumination brightness can be changed (rheostat function). OK: Illumination brightness can be slightly changed (though not significantly). (NG: No change in brightness.)

NG

GO TO STEP 7

OK

(a) Remove the night view switch.

(b) Disconnect the connector from the night view switch.

(c) Measure the resistance between terminals RL and RV of the night view switch. Standard resistance: Switch Condition Specified Condition When turned fully clockwise Approximately 10 kΩ When turned fully counterclockwise Approximately 0 kΩ

NG

REPLACE NIGHT VIEW SWITCH

OK

(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.

REPLACE NIGHT VIEW ECU

OK

REPLACE NIGHT VIEW CAMERA

(b) Turn the ignition switch ON.

(c) Switch to inspection mode .

(d) Measure the voltage between terminal REO of the night view ECU connector "N6" and body ground while rotating rheostat. (Terminals of ECU: ) Standard voltage: The voltage charges within 0 to 5 V when rotating the rheostat.

NG

GO TO STEP 10

OK

(a) Turn the ignition switch ON.

(b) Switch to inspection mode .

(c) Using an oscilloscope, check the output waveform between terminal DIM of the night view ECU connector "C" and body ground. (Terminals of ECU: ) OK: The duty ratio changes (length of "A" becomes shorter) while rotating the night view switch clockwise. (Reference) oscilloscope connection Item Contents Tool setting 2 V/DIV., 1 msec./DIV. Vehicle condition When night view system starts up
