FLUID
OPERATION
1. BEFORE TRANSMISSION FILL

This transmission requires Toyota Genuine ATF WS.

It is necessary to refill the transmission with the correct
amount of fluid.

The vehicle must remain level while adjusting the trans-
mission fluid level.

On vehicles equipped with active suspension, turn the
suspension control switch OFF if it is necessary to jack up
the vehicle with the engine running.
2. TRANSMISSION PAN FILL
(a) Remove the refill plug and overflow plug.
(b) Fill the transmission through the refill hole until fluid be-
gins to trickle out of the overflow tube.
(c) Reinstall the overflow plug.

AIRBAG SENSOR ASSEMBLY

Never reuse the airbag sensor assembly involved in a collision when the SRS has deployed.

The connectors to the airbag sensor assembly should be connected or disconnected with the sensor
mounted on the floor. If the connectors are connected or disconnected while the airbag sensor as-
sembly is not mounted to the floor, it could cause undesired ignition of the supplemental restraint sys-
tem.

Work must be started after 90 seconds from the time the ignition switch is turned to the ºLOCKº posi-
tion and the negative (-) terminal cable is disconnected from the battery, even if only loosening the
set bolts of the airbag sensor assembly.
WIRE HARNESS AND CONNECTOR

The SRS wire harness is integrated with the cowl wire harness assembly and floor wire harness as-
sembly. The wires for the SRS wire harness are encased in a yellow corrugated tube. All the connec-
tors for the system are also a standard yellow color. If the SRS wire harness becomes disconnected
or the connector becomes broken due to an accident, etc., repair or replace it as shown on page.
2. BRAKE SYSTEM
The brake system is one of the most important safety components. Always follow the directions and
notes given in section BR of the repair manual for the relevant model year when handling brake sys-
tem parts.
NOTICE: When repairing the brake master cylinder or TRAC system, bleed the air out of the TRAC
system.
3. DRIVE TRAIN AND CHASSIS
The drive train and chassis are components that can have great effects on the running performance
and vibration resistance of the vehicle. After installing components in the sections listed in the table
below, perform alignments to ensure correct mounting angles and dimensions. Particularly accurate
repair of the body must also be done to ensure correct alignment.
HINT: Correct procedures and special tools are required for alignment. Always follow the directions
given in the repair manual for the relevant model during alignment and section Dl of this manual.
4. COMPONENTS ADJACENT TO THE BODY PANELS
Various types of component parts are mounted directly on or adjacently to the body panels. Strictly ob-
serve the following precautions to prevent damaging these components and the body panels during
handling.

Before repairing the body panels, remove their components or apply protective covers over the com-
ponents.

Before prying components off using a screwdriver or a scraper, etc., attach protective tape to the tool
tip or blade to prevent damaging the components and the body paint.

Before removing components from the outer surface of the body, attach protective tape to the body
to ensure no damage to painted areas.
HINT: Apply touch-up paint to any damaged paint surfaces.

Before drilling or cutting sections, make sure that there are no wires, etc. on the reverse side.

GENERAL INFORMATION
1. BASIC DIMENSIONS
(a) There are two types of dimensions in the diagram.
(Three-dimensional distance)

Straight-line distance between the centers of two
measuring points.
(Two-dimensional distance)

Horizontal distance in forward/rearward between
the centers of two measuring points.

The height from an imaginary standard line.
(b) In cases in which only one dimension is given, left
and right are symmetrical.
(c) The dimensions in the following drawing indicate
actual distance. Therefore, please use the dimen-
sions as a reference.
2. MEASURING
(a) Basically, all measurements are to be done with a
tracking gauge. For portions where it is not possible
to use a tracking gauge, a tape measure should be
used.
(b) Use only a tracking gauge that has no looseness in
the body, measuring plate, or pointers.
HINT:
1. The height of the left and right pointers must be equal.
2. Always calibrate the tracking gauge before measuring or
after adjusting the pointer height.
3. Take care not to drop the tracking gauge or otherwise
shock it.
4. Confirm that the pointers are securely in the holes.
(c) When using a tape measure, avoid twists and
bends in the tape.
(d) When tracking a diagonal measurement from the
front spring support inner hole to the suspension
member upper rear installation hole, measure
along the front spring support panel surface.

DTC P0504 Brake Switch ºAº/ºBº Correlation
CIRCUIT DESCRIPTION
In addition to turning on the stop lamps, the stop lamp switch signals are used for a variety of engine, trans-
mission, and suspension functions as well as being an input for diagnostic checks. It is important that the
switch operates properly, therefore this switch is designed with two complementary signal outputs: STP and
ST1-. The ECM analyzes these signal outputs to detect malfunctions in the stop lamp switch.
HINT:
Normal condition is as shown in the table.
