Toyota Sienna Service Manual: Display Signal Circuit between Video Terminal and Television Display
DESCRIPTION
This is the display signal circuit from the video terminal to the television display assembly.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 CHECK HARNESS AND CONNECTOR (TELEVISION DISPLAY ASSEMBLY - VIDEO TERMINAL)
- Disconnect the connectors from the video terminal and television display assembly.
- Measure the resistance according to the value(s) in the table below.
Standard resistance
2 INSPECT VIDEO TERMINAL
- Reconnect the video (video adapter) terminal connector.
- Measure the waveform according to the table below.
OK
HINT: The waveform pattern may differ from that shown in the illustration below due to differences in oscilloscope setting. A normal video terminal operating condition can be determined if any waveform is output.
- Oscilloscope waveform
- Terminal: NTSC - Body ground
Setting: 200mV/DIV, 10 μs/DIV
Condition: DVD display is ON.

On-vehicle inspection
1. INSPECT BRAKE BOOSTER
(a) Air tightness check.
(1) Start the engine and stop it after 1 or 2 minutes.
Depress the brake pedal several times slowly.
HINT:
If the pedal goes down farthest at the 1st time,
and gradually rises at the 2nd or 3rd time, the
booster is airtight.
(2) Depre ...

Shift Solenoid "D" Performance (Shift Solenoid
Valve S4)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor to detect the actual gear
position (1st, 2nd, 3rd, 4th
or 5th gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory
to detect mechanical
problems of the shift solenoid valves, valve b ...
