(c) Install the antenna feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the vehicle's
electronics systems. For details about ECU and sensors locations, refer to the section on the applica-
ble component.
(d) Do not wind the antenna feeder together with the other wiring. As much as possible, also avoid running
the antenna feeder parallel with other wire harnesses.
(e) Confirm that the antenna and feeder are correctly adjusted.
(f) Do not install powerful mobile communications system.
4. FOR USING OBDII SCAN TOOL OR TOYOTA HAND-HELD TESTER
Observe the following for safety reasons:

Before using the OBDII scan tool or TOYOTA hand-held tester, the OBDII scan tool's instruction
book or TOYOTA hand-held tester's operator manual should be read thoroughly.

Be sure to route all cables securely when driving with the OBDII scan tool or TOYOTA hand-held
tester connected to the vehicle. (i.e. Keep cables away from feet, pedals, steering wheel and shift
lever.)

Two persons are required when test driving with the OBDII scan tool or TOYOTA hand-held tes-
ter, one person to drive the vehicle and one person to operate the OBDII scan tool or TOYOTA
hand-held tester.
5. FOR VEHICLES EQUIPPED WITH TRACTION CON-
TROL (TRAC) SYSTEM
When using a 2 wheel drum tester such as a speedometer tes-
ter or chassis dynamometer, etc., or jacking up the rear wheels
and driving the wheels, always push in the TRAC cut (ºTRAC
OFFº) switch and turn the TRAC system OFF.
(a) Confirm TRAC system is OFF
(1) Press the TRAC cut (ºTRAC OFFº) switch.
(2) Check that the TRAC OFF indicator light comes on
when the TRAC system is turned off by the TRAC
cut switch.
HINT:
The TRAC OFF indicator light should always operate right after
the engine is restarted.
(3) Begin measurements.

HANDLING PRECAUTIONS ON RELATED COMPONENTS
1. SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Servicing vehicle with a Supplemental Restraint System (referrerd to as the SRS in the remainder of this
manual) installed.
When handling SRS components (removal, installation or inspection, etc.), always follow the directions
given in the repair manual for the relevant model year to prevent the occurrence of accidents and airbag
malfunction.
Also take the following precautions when repairing the body:

Work must be started after 90 seconds or longer from the time the ignition switch is set to the LOCK
position and the negative (-) terminal cable is disconnected from the battery.
(The airbag system is equipped with a backup power source so that if work is started within 20 seconds
of disconnecting the negative (-) terminal cable of the battery, the airbag may be deployed.)
When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio
systems will be cancelled. So before starting work, make a record of the contents memorized by each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat, outside rear view mirror and power shoul-
der belt anchorage, which are all equipped with memory function, it is not possible to make a record of
the memory contents. So when the operation is finished, it will be necessary to explain this fact to the
customer, and request the customer to adjust the features and reset the memory.

When using electric welding, first disconnect the SRS connector (yellow color and 2 pins) under the
steering column near the combination switch connector on the glove compartment finish plate and lower
the front scuff plate before starting work.

5. COMPONENTS ADJACENT TO THE BODY PANELS Locations of ECUs (Cont'd)
Many ECUs are mounted in this vehicle.
Take the following precautions during body repair to prevent damage to the ECUs.

Before starting electric welding operations, disconnect the negative (-) terminal cable from the battery.
When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio
systems will be cancelled. So before starting work, make a record of the contents memorized by each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat and outside rear view mirror, which are all
equipped with memory function, it is not possible to make a record of the memory contents.
So when the operation is finished, it will be necessary to explain this fact to the customer, and request
the customer to adjust the features and reset the memory.

Do not expose the ECUs to ambient temperatures above 80°C (176°F).
NOTICE: if it is possible the ambient temperature may reach 80°C (176°F) or more, remove the ECUs
from the vehicle before starting work.

Be careful not to drop the ECUs and not to apply physical shocks to them.
Various types of component parts are mounted directly on or adjacently to the body panels.
Strictly observe 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
components.

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