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.
