Toyota Sienna Service Manual: TS and CG Terminal Circuit
DESCRIPTION
In the sensor check mode, a malfunction of the speed sensor that cannot be detected when the vehicle is stopped is detected while driving.
Transition to the sensor check mode can be performed by connecting terminals TS and CG of the DLC3 and turning the ignition switch from off to the ON position.

Fuel Pump Control Circuit
DESCRIPTION
The FUEL PUMP relay switches the fuel pump speed according to the engine
conditions. The fuel pump
operates when the ECM receives the starter-operating signal (STA) and
crankshaft-rotating signal (NE).
The FUEL PUMP relay is turned ON while the engine is idling or operating at l ...

If you use chains or cables to tie
down your vehicle, the angles
shaded in black must be 45.
Do not overly tighten the tie
downs or the vehicle may be damaged.
WARNINGObserve the following precautions.
Failure to do so may result in death or serious injury.

Air Mix Damper Position Sensor Circuit (Passenger Side)
DESCRIPTION
This sensor detects the position of the air mix control servo motor (air mix
damper) and sends the
appropriate signals to the A/C amplifier. The position sensor is built in the
air mix control servo motor. The
position sensor's resistance changes as the air mix control servo m ...
