curtain air bag.
INSTALLATION
Install in the reverse order of removal.
CAUTION:
Never use old fixing nuts after removal; replace with new nuts.
In the case that a malfunction is detected by the air bag warning lamp, after repair or replacement of
the malfunctioning parts, reset the memory by self-diagnosis or by CONSULT-III.
After the work is completed, check that no system malfunction is detected by air bag warning lamp.

WARNING:
Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait at least 3
minutes.
Before disconnecting the diagnosis sensor unit harness connector, be sure to disconnect each har-
ness connector of the air bag module and pre-tensioner seat belt to prevent air bag deployment by
static electricity and pre-tensioner seat belt operation.
Never use air tools or electric tools for servicing.
REMOVAL
1. Disconnect each connector of all air bag modules and pre-tensioner seat belts.
2. Remove the center console assembly. Refer to IP-22, "

SRS AIR BAG SYSTEM
3. Detects and records the deployment of air bag and seat belt pre-tensioner, and turns on air bag warning
lamp.
4. Indicates malfunctioning portion with blinking times of air bag warning lamp in diagnosis mode.
5. Indicates the malfunctioning record by CONSULT-III.

Component DescriptionINFOID:0000000003813933
Air bag diagnosis sensor units are prepared for operation while the ignition switch is in the ON or START
position.
The operation of Supplemental Restraint System is different from collision modes application. For example,
the driver air bag module and front passenger air bag module are activated in a frontal collision but not in a
side collision.
SRS configurations which are activated for some collision modes are as follows.
1. Front passenger air bag module M62 2. Driver air bag module M350 3. Conbination switch (Spiral cable)
