Power TOYOTA CAMRY 2000 Service Owner's Guide

CIRCUIT DESCRIPTION
The rotary solenoid type IAC valve is provided on the intake air chamber and intake air bypassing
the throttle valve is directed to the IAC valve through a passage.
In this way the intake air volume bypas±
sing the throttle valve is regulated, con±
trolling the engine speed.
The ECM operated only the IAC valve to
perform idle±up and provide feedback for
the target idling speed, a VSV for idle±up
control is also added (for air condition±
ing).
Check for open and short in harness and
connector between J/B No.2 and IAC valve,
IAC valve and ECM.
IAC Valve Circuit
Repair or replace harness or connector. Check voltage terminals ISCO, ISCC.
Check for ECM power source circuit.
DIAGNOSTIC CHART

CIRCUIT DESCRIPTION
Fuel pump control
The fuel pump is switched on (low voltage at terminal FC) when STA is on or while the NE signal
is input to the ECM.
In the diagram below, when the engine is cranked, current flows from terminal ST of the ignition
switch to the starter relay coil, the starter relay switches on and current flows to coil L1 of the circuit
opening relay. Thus the circuit opening relay switches on, power is supplied to the fuel pump and the
fuel pump operates.
When the STA signal and NE signal are input to the ECM, Tr is turned ON, current flows to coil L2
of the circuit opening relay, the relay switches on and the fuel pump operates.
While the NE signal is generated (engine running), the ECM keeps Tr ON (circuit opening relay ON)
and the fuel pump also keeps operating.

CIRCUIT DESCRIPTION
VSV Circuit for Fuel Pressure Control (Only for California
spec.)
Check for open and short in harness and
connector between EFI main relay and ECM.Proceed to next circuit inspection
shown on matrix chart
(See page EG1±327).
Repair or replace harness or connector. Check voltage of VSV power source. Check VSV for fuel pressure control.
Check and replace ECM.Replace VSV.
DIAGNOSTIC CHART
The ECM turns on a VSV (Vacuum Switching
Valve) to draw the air into the diaphragm chamber
of the pressure regulator if it detects that the tem-
perature of the engine coolant is too high during
engine starting. The air drawn into the chamber
increases the fuel pressure to prevent fuel vapor
lock at high engine temperature in order to help the
engine start when it is warm.
Fuel pressure control ends approx. 90 secs. after
the engine is started.

2. Rear Lights
The rear combination light has adopted a
construction in which the light extends to the end
of the lens. Thus, as a result of expanding the
effective luminance area, the visibility from
other vehicles has been improved.
The light diffusion characteristic of the back±up
light has been revised to improve further
visibility when backing up at night.
 MOON ROOF
A power tilt±up and sliding moon roof is optional equipment for LE and XLE grade models. A one±touch slide±open
function is added.
 WINDSHIELD GLASS AND WINDOW GLASS
The front windshield, the rear window, and all door windows use the type of glass that dramatically shuts out ultraviolet
and infrared rays. As a result, sunburns from ultraviolet rays and heat from infrared rays have been reduced and reduction
of heat load to the air conditioning system.

 SEATS
1. Front Seat
Genuine leather seats are available as an option on the LE and XLE grade models.
Power seats are available as an option on the LE grade model and as standard equipment on the XLE grade model.
2. Rear Seat
Built±in CRS (Child Restraint System) is available as an option on all models.

 TILT STEERING
The tilt steering is standard on all models.
The steering wheel position can be changed to any of 6 positions..
 POWER WINDOW SYSTEM
A power window system is standard on the LE and XLE grade models and optional on the CE grade model. The power
window system includes one±touch auto down and key±off operation functions. The one±touch auto down function
automatically opens the driver's side window fully. The key±off operation function makes it possible to operate the
power windows for approximately 45 seconds after the ignition key is turned to the ACC or LOCK position, if the
front doors are not opened.
 DOOR LOCK CONTROL SYSTEM
The door lock control system with 2±step unlock function is standard on the LE and XLE grade model and optional
as a set with the power window system on the CE grade model. With the 2±step function, turning the key once in
the driver's door unlocks the driver's door only. Turning it twice unlocks all the doors.
A key confinement prevention function is provided. When the door is opened and the door lock button is locked
with the key still inserted in the ignition key cylinder, the key confinement prevention mechanism immediately
turns the door lock button to unlock. This prevents the key from being inadvertently locked inside the vehicle.
