B1212, B1213, B1214 RH1 SAT-SENS
DescriptionINFOID:0000000003941406
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 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
RH satellite sensor is installed at the underside of center pillar with fixed nuts.
DTC LogicINFOID:0000000003941407
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-126, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003941408
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.

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.
