B1120, B1121 SATELLITE SENS LH
B1120, B1121 SATELLITE SENS LH
DescriptionINFOID:0000000003814023
Main “G” sensor generates signal voltage, when it detects deceleration beyond the specified level by vehicle
side collision.
OPERATION
When air bag diagnosis sensor unit defines both signal voltage of the “G” sensor and the safing algorithm to
be that of collision which exceeds a specified level, the driving circuit switches on and feeds the electric ignitor
of both the front side air bag and side curtain air bag.
STRUCTURE
Integrated type of the “G” sensor element for side collision with output terminals for signal voltage.
INSTALLATION
LH satellite sensor is installed at the underside of center pillar with fixed nuts.
DTC LogicINFOID:0000000003814024
DTC CONFIRMATION PROCEDURE
1.CHECK SELF-DIAG RESULT
With CONSULT-III
1. Turn ignition switch ON.
2. Perform “AIR BAG” Self Diagnostic Result.
Without CONSULT-III
1. Turn ignition switch ON.
2. Check the air bag warning lamp status. Refer to SRC-10, "
Air Bag Warning Lamp Diagnosis".
NOTE:
SRS does not enter Diagnosis mode if no malfunction is detected in User mode.
Is malfunctioning part detected?
YES >> Refer to SRC-78, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003814025
WARNING:
 Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait at least 3
minutes. (To discharge backup capacitor.)
 Never use unspecified tester or other measuring device.

DescriptionINFOID:0000000003814026
Check the whole SRS and displays the malfunction either by illuminating or blinking the air bag warning lamp
in the combination meter. Malfunctioning part can be detected by on board self-diagnosis system and CON-
SULT-III.
OPERATION
It detects a shock that exceeds a specified level and monitors whether the driver and passenger air bags, front
side air bag, side curtain air bag and pre-tensioner seat belts operate normally.
STRUCTURE
It contains the “G” sensors for both frontal and side collisions and spare battery function in case of main bat-
tery damage in collision.
INSTALLATION
Air bag diagnosis sensor unit is installed under the center console with fixed bolts.

B1129 SIDE MODULE RH
B1129 SIDE MODULE RH
DescriptionINFOID:0000000003814029
For front RH side air bag module, crash is judged by main “G” sensor output signal (left side: LH satellite sen-
sor, right side: RH satellite sensor) and safing algorithm (in air bag diagnosis sensor unit).
OPERATION
In case of frontal collision whose acceleration exceeds the specified level, the ignition materials are ignited by
electric ignition system. The system burns the gas generating materials resulting in a chemical reaction. This
generates hot gases that flow into the air bag through a filter and expand the bag.
STRUCTURE
Front RH side air bag module mainly consists of air bag and inflator which inflates air bag.
INSTALLATION
Front RH side air bag module is installed on the side of front seat back with fixed nuts.
