WARNING:

• Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait 3 minutes

or more.

• Before disconnecting the air bag sensor unit harness connector, be sure to disconnect the 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 the air tools or electric tools for servicing.
• When replacing the air bag diagnosis sensor unit, always check with the parts department for the lat-

est parts information. Installing an incorrect air bag diagnosis sensor unit may or may not cause the
air bag warning lamp to illuminate and may cause incorrect deployment of the supplemental air bags
and seat belt pre-tensioners in a collision resulting in serious personal injury or death.

REMOVAL

1.

Always check the air bag diagnosis sensor unit ECU discriminated number (identification number) using
CONSULT.

2.

Disconnect the each connector of all air bag modules and pre-tensioner seat belts.

3.

Remove the instrument lower cover (LH and RH). Refer to 

IP-20, "Exploded View"

.

4.

Remove the rear foot duct 1 (LH and RH). Refer to 

VTL-125, "REAR FOOT DUCT 1 : Exploded View"

.

5.

Remove the instrument stay LH. Refer to 

IP-20, "Exploded View"

.

6.

Remove the front console bracket. Refer to 

IP-20, "Exploded View"

.

7.

Disconnect the diagnosis sensor unit harness connectors.

8.

Remove the fixing bolts, ground bolt, and then remove the diagnosis sensor unit. 

CAUTION:

[FOR MEXICO]

DIAGNOSIS SENSOR UNIT

• Replace the diagnosis sensor unit if it has been dropped or

sustained an impact.

• Replace the diagnosis sensor unit of deployed SRS air bag and deployed SRS front seat belt pre-ten-

sioner. 

INSTALLATION

Install air bag diagnosis sensor unit in the reverse order of removal.

CAUTION:

• Never use the old fixing bolts after removal, replace with the new fixing bolts.
• If malfunction is detected by the air bag warning lamp, after repair or replacement of the malfunc-

tioning parts, reset the memory using self-diagnosis or CONSULT. Refer to 

SRC-83, "Description"

.

• After the work is completed, check that no system malfunction is detected by air bag warning lamp.
• After replacing the air bag diagnosis sensor unit, confirm using CONSULT that the ECU discrimi-

nated number (identification number) of the new replacement air bag sensor unit matches the ECU
discriminated number (identification number) of the replaced (old) air bag diagnosis sensor unit.

NOTE:
If the ECU discriminated number of the new replacement air bag diagnosis sensor unit differs from the ECU
discriminated number of the replaced air bag diagnosis sensor unit, reconfirm the parts information and verify
that the correct air bag diagnosis sensor unit was installed.

SRS AIR BAG SYSTEM

System Diagram

INFOID:0000000008454540

System Description

INFOID:0000000008454541

Supplemental Restraint System (SRS) activates air bag module and seal belt pre-tensioner when it detects a
frontal collision or a side collision that is more than the specified limit. Together with other safety devices, it
reduces the impact that occupant receives when vehicle collision occurs.
Air bag diagnosis sensor unit supplies power supply to air bag module and pre-tensioner seat belt when decel-
eration that is more than the specified limit is detected by G sensor in air bag diagnosis sensor unit, crash
zone sensor, or satellite sensor. Air bag module is composed of electric igniter (squib), filter, pyrotechnic mate-
rial, and gas generating material. When air bag module receives a signal from air bag diagnosis sensor unit,
air bag module ignites pyrotechnic material using electric igniter (squib) so that gas generating material gener-
ates high temperature nitrogen gas. The gas through filter activates air bag and seat belt pre-tensioner.

AIR BAG DIAGNOSIS SENSOR UNIT FUNCTIONS

Air bag diagnosis sensor unit has the following functions.
• Detects a collision and supplies the energy for deploying air bag and seat belt pre-tensioner.
• Detects and records electrical malfunction in air bag system and seat belt pre-tensioner system, and blinking

air bag warning lamp.

• Detects and records the deployment of air bag and seat belt pre-tensioner, and turns ON air bag warning

lamp.

JMHIA1410GB

< SYSTEM DESCRIPTION >

[FOR USA AND CANADA]

SRS AIR BAG SYSTEM

• Indicates malfunctioning portion with blinking times of air bag warning lamp in diagnosis mode.
• Indicates the malfunction record via CONSULT.
• Suppresses the deployment of passenger air bag when passenger seat is empty or occupied by child or

child-seat.

• When passenger seat is occupied by child or child seat, turns ON passenger air bag OFF indicator. 
• When judges that passenger seat is occupied by a adult or a child and passenger seat belt is not fasten,

turns ON seat belt warning lamp. Further information for the seat belt warning system, refer to 

SRC-13,

"System Description"

.

COLLISION MODE

• The operation of supplemental restraint system is different depending on the collision modes applications.

For example, the driver air bag module, front passenger air bag module and front seat belt pre-tensioner are
activated in a frontal collision but not in a side collision.

• SRS configurations that are activated for some collision modes are as per the following.
