WARNING!
SDM
• For handling and storage of a SDM, select
a place where the ambient temperature
below 65 °C (150 °F), without high humidity
and away from electric noise.
• During service procedures, be very careful
when handling a Sensing and Diagnostic
Module (SDM). Never strike or jar the SDM.
• Never power up the air bag system when
the SDM is not rigidly attached to the
vehicle. All SDM and mounting bracket
fasteners must be carefully torqued and
the arrow must be pointing toward the
front of the vehicle to ensure proper
operation of the air bag system.
The SDM could be activated when powered
while not rigidly attached to the vehicle
which could cause deployment and result
in personal injury.

WARNING!
Driver and Passenger Seat Belt
Pretensioners
• For handling and storage of a live seat belt
pretensioner, select a place where the
ambient temperature below 65 °C (150 °F),
without high humidity and away from
electric noise.
• Never carry seat belt pretensioner by wire
or connector of pretensioner. When
placing a live seat belt pretensioner on the
workbench or some place like that, never
put something on seat belt pretensioner.
Otherwise, personal injury may result.
• Never dispose of live (inactivated) seat belt
pretensioners (drive and passenger). If
disposal is necessary, be sure to activate
them according to activation procedures
described in “Air Bag (Inflator) Module and
Seat Belt Pretensioner Disposal in Section
8B” before disposal.
• The seat belt pretensioner immediately
after activation is very hot. Wait for at least
half an hour to cool it off before
proceeding the work.
• With many service procedures, gloves and
safety glasses should be worn to prevent
any possible irritation of the skin or eyes.

• Even when the accident was light enough not to
cause air bags to activate, be sure to inspect system
parts and other related parts according to instructions
under “Repair and Inspection Required after Accident
in Section 8B”.
• When servicing parts other than air bag system, if
shocks may be applied to air bag system component
parts, remove those parts beforehand.
• When handling the air bag (inflator) modules (driver,
passenger, side and curtain), seat belt pretensioners
(driver and passenger), forward sensor, side sensors
or SDM, be careful not to drop it or apply an impact to
it. If an excessive impact was applied, never attempt
disassembly or repair but replace it with a new one.
• When grease, cleaning agent, oil, water, etc. has got
onto air bag (inflator) modules (driver, passenger, side
and curtain) or seat belt pretensioners (drive and
passenger), wipe off immediately with a dry cloth.
• Air bag wire harness is included in floor and
instrument panel wire harnesses. Air bag wire
harness branched off from floor and instrument panel
wire harnesses can be identified easily as it is covered
with a yellow protection tube and it has yellow
connectors. Be very careful when handling it.
• When an open in air bag wire harness, damaged wire
harness, connector or terminal is found, replace wire
harness, connectors and terminals as an assembly.
• Do not apply power to the air bag system unless all
components are connected or a diagnostic flow
requests it, as this will set a DTC.
• Never use air bag system component parts from
another vehicle.
• When using electric welding, be sure to disconnect all
air bag (inflator) module connectors and pretensioner
connectors from air bag wire harness respectively.
• Never expose air bag system component parts
directly to hot air (drying or baking the vehicle after
painting) or flames.
• WARNING / CAUTION labels are attached on each
part of air bag system components. Be sure to follow
the instructions.
• After vehicle is completely repaired, perform “Air Bag
Diagnostic System Check in Section 8B”.
General PrecautionsS6RW0D0000002
The WARNING and CAUTION describe some general
precautions that you should observe when servicing a

Precautions for Installing Mobile
Communication Equipment
S6RW0D0000005
When installing mobile communication equipment such
as CB (Citizens-Band)-radio or cellular-telephone, be
sure to observe the following precautions.
Failure to follow cautions may adversely affect electronic
control system.
• Keep the antenna as far away as possible from the
vehicle’s electronic control unit.
• Keep the antenna feeder more than 20 cm (7.9 in.)
away from electronic control unit and its wire
harnesses.
• Do not run the antenna feeder parallel with other wire
harnesses.
• Confirm that the antenna and feeder are correctly
adjusted.
Precaution for CAN Communication SystemS6RW0D0000006
• The loose (1) in the wire harnesses twist of the CAN
lines except around the connector (3) should be within
100 mm (3.9 in.). Refer to the wiring diagram for the
CAN lines discrimination. Excessively-loosed lines
may be influenced by the electric noise.
• Do not connect terminals of the CAN line using a
bypass wire (1). Otherwise, the CAN line may be
influenced by the electric noise.
Precautions for Electrical Circuit ServiceS6RW0D0000007
• When replacing a fuse, make sure to use a fuse of the
specified capacity. Use of a fuse with a larger capacity
will cause a damage to the electrical parts and a fire.
• When disconnecting and connecting coupler, make
sure to turn ignition switch OFF, or electronic parts
may get damaged.
• When disconnecting connectors, never pull the wiring
harness. Unlock the connector lock first and then pull
them apart by holding connectors themselves.

Downloaded from www.Manualslib.com manuals search engine 00-9 Precautions:
• When connecting connectors, also hold connectors
and put them together until they lock securely (a click
is heard).
• When installing the wiring harness, fix it with clamps
so that no slack is left.
• When installing vehicle parts, be careful so that the
wiring harness is not interfered with or caught by any
other part.
• To avoid damage to the harness, protect its part which
may contact against a part forming a sharp angle by
winding tape or the like around it.• Be careful not to touch the electrical terminals of parts
which use microcomputers (e.g. electronic control unit
like as ECM, PCM, P/S controller, etc.). The static
electricity from your body can damage these parts.
• Never connect any tester (voltmeter, ohmmeter, or
whatever) to electronic control unit when its coupler is
disconnected. Attempt to do it may cause damage to
it.
• Never connect an ohmmeter to electronic control unit
with its coupler connected to it. Attempt to do it may
cause damage to electronic control unit and sensors.
• Be sure to use a specified voltmeter / ohmmeter.
Otherwise, accurate measurements may not be
obtained or personal injury may result. If not specified,
use a voltmeter with high impedance (M Ω/V
minimum) or a digital type voltmeter.
• When taking measurements at electrical connectors
using a tester probe, be sure to insert the probe (2)
from the wire harness side (backside) of the
connector (1).

• When connecting meter probe (2) from terminal side
of coupler (1) because it can’t be connected from
harness side, use extra care not to bend male
terminal of coupler of force its female terminal open
for connection.
In case of such coupler as shown connect probe as
shown to avoid opening female terminal.
Never connect probe where male terminal is
supposed to fit.
• When checking connection of terminals, check its
male half for bend and female half for excessive
opening and both for locking (looseness), corrosion,
dust, etc.
• Before measuring voltage at each terminal, check to
make sure that battery voltage is 11 V or higher. Such
terminal voltage check at low battery voltage will lead
to erroneous diagnosis.Air Bag WarningS6RW0D0000008

Electrical Circuit Inspection ProcedureS6RW0D0006001
While there are various electrical circuit inspection
methods, described here is a general method to check
its open and short circuit by using an ohmmeter and a
voltmeter.
Open Circuit Check
Possible causes for the open circuit are as follows. As
the cause is in the connector or terminal in many cases,
they need to be checked particularly carefully.
• Loose connection of connector
• Poor contact of terminal (due to dirt, corrosion or rust
on it, poor contact tension, entry of foreign object etc.)
• Wire harness being open
When checking system circuits including an electronic
control unit such as ECM, TCM, ABS control module,
etc., it is important to perform careful check, starting with
items which are easier to check.
1) Disconnect negative (–) cable from battery
2) Check each connector at both ends of the circuit
being checked for loose connection. Also check lock
condition of connector if equipped with connector
lock.
3) Using a test male terminal, check both terminals of
the circuit being checked for contact tension of its
female terminal. Check each terminal visually for
poor contact (possibly caused by dirt, corrosion, rust
entry of foreign object, etc.). At the same time, check
to make sure that each terminal is locked in the
connector fully.4) Using continuity check or voltage check the following
procedure, check the wire harness for open circuit
and poor connection with its terminals. Locate
abnormality, if any.
Continuity Check
1) Measure resistance between connector terminals at
both ends of the circuit being checked (between “A-
1” and “C-1” in the figure). If no continuity is indicated
(infinity or over limit), that means that the circuit is
open between terminals “A-1” and “C-1”.
2) Disconnect the connector included in the circuit
(connector-B in the figure) and measure resistance
between terminals “A-1” and “B-1”.
If no continuity is indicated, that means that the
circuit is open between terminals “A-1” and “B-1”. If
continuity is indicated, there is an open circuit
between terminals “B-1” and “C-1” or an abnormality
in connector-B.
1. Check contact tension by inserting and removing just for once.

Voltage Check
If voltage is supplied to the circuit being checked, voltage
check can be used as circuit check.
1) With all connectors connected and voltage applied to
the circuit being checked, measure voltage between
each terminal and body ground.
a) If measurements were taken as shown in the
figure and results were as listed in the following,
it means that the circuit is open between
terminals “B-1” and “A-1”.
Voltage between
“C-1” and body ground: Approx. 5 V
“B-1” and body ground: Approx. 5 V
“A-1” and body ground: 0 V
b) Also, if measured values were as listed in the
following, it means that there is a resistance
(abnormality) of such level that corresponds to
the voltage drop in the circuit between terminals
“A-1” and “B-1”.
Voltage between
“C-1” and body ground: Approx. 5 V
“B-1” and body ground: Approx. 5 V
“A-1” and body ground: Approx. 3 VShort Circuit Check (Wire Harness to Ground)
1) Disconnect negative (–) cable at battery.
2) Disconnect connectors at both ends of the circuit to
be checked.
NOTE
If the circuit to be checked is connected to
other parts (1), disconnect all connectors of
those parts.
Otherwise, diagnosis will be misled.

3) Measure resistance between terminal at one end of
circuit (“A-1” terminal in the figure) and body ground.
If continuity is indicated, it means that there is a short
to ground between terminals “A-1” and “C-1” of the
circuit.
4) Disconnect the connector included in circuit
(connector-B) and measure resistance between “A-
1” and body ground. If continuity is indicated, it
means that the circuit is shorted to the ground
between terminals “A-1” and “B-1”.

Intermittent and Poor Connection InspectionS6RW0D0006002
Most intermittent are caused by faulty electrical
connections or wiring, although a sticking relay or
solenoid can occasionally be at fault. When checking it
for proper connection, perform careful check of suspect
circuits for:
• Poor mating of connector halves, or terminals not fully
seated in the connector body (backed out).
• Dirt or corrosion on the terminals. The terminals must
be clean and free of any foreign material which could
impede proper terminal contact. However, cleaning
the terminal with a sand paper or the like is prohibited.
• Damaged connector body, exposing the terminals to
moisture and dirt, as well as not maintaining proper
terminal orientation with the component or mating
connector.
• Improperly formed or damaged terminals.
Check each connector terminal in problem circuits
carefully to ensure good contact tension by using the
corresponding mating terminal.
If contact tension is not enough, reform it to increase
contact tension or replace.• Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor
connection by shaking it by hand lightly. If any
abnormal condition is found, repair or replace.
• Wire insulation which is rubbed through, causing an
intermittent short as the bare area touches other
wiring or parts of the vehicle.
• Wiring broken inside the insulation. This condition
could cause continuity check to show a good circuit,
but if only 1 or 2 strands of a multi-strand-type wire
are intact, resistance could be far too high.
If any abnormality is found, repair or replace.
1. Check contact tension by inserting and removing just once.
2. Check each terminal for bend and proper alignment.
