General Information - Repair Instruction1-6IllustrationRemoval/installation2. For Vehicles Equipped With SRS Airbag and Seat Belt Pretensioner
Tip: This is equipped with an SRS (Supplemental Restraint System), such as the driver airbag assembly,
front passenger airbag assembly airbag ECU and seat belt pretensioner. Failure to carry out service operations in
the correct sequence could cause the supplemental restraint system to unexpectedly deploy during servicing,
possibly leading to a serious accident. Further, if a mistake is made in servicing the supplemental restraint
system, it is possible the SRS may fail to operate when required. Before servicing (including removal or instal-
lation of parts, inspection or replacement), be sure to read the following items carefully, then follow the correct
procedure described in this manual.
(1) General NoticeInstall Remove
Install Remove a. Malfunction symptoms of the supplemental restraint system are difficult to confirm, so the diagnostic
trouble codes become the most important source of information when troubleshooting. When troubleshooting
the supplemental restraint system, always inspect the diagnostic trouble codes before disconnecting the battery.
b. Work must be started after 90 seconds from the time the ignition switch is turned to the "LOCK"
position and the negative (-) terminal cable is disconnected from the battery. (The supplemental restraint system
is equipped with a back--up power source so that if work is started within 90 seconds of disconnecting the
negative (-) terminal cable from the battery, the SRS may deploy.) 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 the each memory system. Then when work is finished, reset
the clock and audio systems as before. To avoid erasing the memory of each memory system, never use a back-
up power supply from another battery.

General Information - Repair Instruction1-93. Electronic Control Device
(1) Removal of the battery terminal cable
a. Before performing electrical servicing, disconnect the nega-
tive (-) cable from the battery in order to avoid short for burnout.
b. When disconnecting the terminal cable, turn off the ignition
and light switches, loosen the cable nut and raise the cable straight
up without twisting or prying it.
c. When disconnecting the terminal cable from the battery, all
information stored in the clock, radio and DTC shall be deleted,
therefore, these information shall be checked before disconnection.
(2) Processing of Electronic Parts
a. Do not open the cover or case of the ECU unless absolutely
necessary. (If the IC terminals are touched, the IC may be destroyed
by static electricity.)
b. To pull apart electrical connectors, pull on the connector itself,
not the wires.
c. Be careful not to drop electrical components, such as ECU
or relays. If they are dropped on a hard floor, they should be replaced
and not reused.
d. When steam cleaning an engine, protect the electronic
components, air filter and emission-related components from water.
e. Never use an impact wrench to remove or install tempera-
ture switches or temperature sensors.
f. When checking continuity at the wire connector, insert the
tester probe carefully to prevent terminals from bending.
4. Remove and Installation of Engine Intake Parts
(1) If any metal scrap is mixed in the inlet pass, that may give
a bad effect to the engine.
(2) When removing and installing of the inlet system parts, close (6) Airbag ECU
a. Never reuse the airbag ECU involved in a collision when the SRS has deployed.
b. The connectors to the airbag sensor assembly should be connected or disconnected with the airbag ECU
mounted on the floor. If the connectors are connected or disconnected while the airbag ECU is not mounted to
the floor, it could cause undesired inflation of the supplemental restraint system.
c. Work must be started after 60 seconds from the time the ignition switch is turned to the "LOCK" position
and the negative (-) terminal cable is disconnected from the battery, even if only loosing the set bolts of the
airbag ECU.
(7) Wire Harness and Connector
The SRS wire harness is integrated with the instrument panel wire harness assembly. All the connectors in
the system are 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.Negative(-)
