5. CHECK FOR INTERMITTENT PROBLEMS
TOYOTA HAND±HELD TESTER only:
By putting the vehicle's ECM in check mode, 1 trip detection logic is possible instead of 2 trip detection logic
and sensitivity to detect open circuits is increased. This makes it easier to detect intermittent problems.
(1) Clear the DTC (See page DI±3).
(2) Set the check mode (See page DI±3).
(3) Perform a simulation test (See page IN±21).
(4) Check the connector and terminal (See page IN±31).
(5) Handle the connector (See page IN±31).
6. BASIC INSPECTION
When the malfunction code is not confirmed in the DTC check, troubleshooting should be performed in the
order for all possible circuits to be considered as the causes of the problems. In many cases, by carrying
out the basic engine check shown in the following flow chart, the location causing the problem can be found
quickly and efficiently. Therefore, use of this check is essential in engine troubleshooting.
1 Is battery positive voltage 11 V or more when engine is stopped?
NO Charge or replace battery.
YES

INSPECTION
1. INSPECT INTAKE AIR CONTROL VALVE
(a) With 26.7 kPa (200 mmHg, 7.9 in.Hg) of vacuum applied
to the actuator, check that the actuator rod moves.
(b) One minute after applying the vacuum in (a), check that
the actuator rod does not return.
If the operation is not as specified, replace the intake air control
valve.
2. INSPECT VACUUM TANK
LOCATION: The LH side member under the battery tray.
(a) Check that air flows from port B to port A.
(b) Check that air does not flow from port A to port B.
(c) Plug port B with your finger, and apply 26.7 kPa (200
mmHg, 7.9 in.Hg) of vacuum to port A, and check that
there is no change is vacuum after one minute.
If the operation is not as specified, replace the vacuum tank.
3. INSPECT VSV (See page SF±60)

PORT INSTALLED RS3000 TVIP TRUNK COURTESY CONNECTION ± AX003±00 March 31, 2000
Page 2 of 2
New Location:
These steps below are to be followed to
locate the new trunk courtesy connection
when servicing Camry vehicles equipped
with the PIO RS3000 TVIP.
1. Remove the negative battery cable.
2. Remove the driver's step cover.
3. Remove the driver's cowl cover (1
nut).
4. Locate the Connector Junction Block
in the driver's cowl area. You will
notice a RED/YELLOW wire routed to
the Blue 10P connector which
terminates at an adjacent splicing
connector. This is the TVIP Trunk
Courtesy Wire.
5. Disconnect the Blue 10P connector
from the Connector Junction Block.
With the tab of the Blue 10P
connector facing up, look at the back
(wire side) and locate the wire in the
bottom row, second space from the
right, which has the splicing connector
attached to it. This is the Vehicle's
Trunk Courtesy Signal Wire.
6. After completing the parts inspection
and repairs if applicable, reconnect
the Blue 10P connector and install all
previously removed parts.
Previous Location:
The White 1P connector for the Vehicle's
Trunk Courtesy Signal is located at the
trunk courtesy lamp switch near the trunk
latch in the vehicle's trunk.

continue on to step 2.
A. Click on the text ªInstall MUW.º (Figure 2.)
B. The file download window will appear. Click on ªRun this program from it's current
location.º
C. Click the ªOKº button.
D. Allow the Update Wizard to perform its self±installation. This will take only a few
minutes.

HOW TO USE THIS MANUAL B
This manual provides information on the electrical circuits installed on vehicles by
dividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where the power
source is received from the battery as far as each ground point. (All circuit
diagrams are shown with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuit
where the problem was detected (see System Circuit section), the power source
supplying power to that circuit (see Power Source section), and the ground points
(see Ground Point section). See the System Outline to understand the circuit
operation.
When the circuit operation is understood, begin troubleshooting of the problem
circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing
sections to find each part, junction block and wiring harness connectors, wiring
harness and wiring harness connectors, splice points, and ground points of each
system circuit. Internal wiring for each junction block is also provided for better
understanding of connection within a junction block.
Wiring related to each system is indicated in each system circuit by arrows
(from__, to__). When overall connections are required, see the Overall Electrical
Wiring Diagram at the end of this manual.
