< COMPONENT DIAGNOSIS >
B1148 CURTAIN MODULE RH
B1148 CURTAIN MODULE RH
DescriptionINFOID:0000000003814065
For RH side curtain air bag module, crash is judged by main “G” sensor output signal (left side: LH satellite
sensor, right side: RH satellite sensor) and safing algorithm (left and right GP 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
RH side curtain air bag module mainly consists of air bag and inflator which inflates air bag.
INSTALLATION
RH side curtain air bag module is installed on the roof side with fixed bolts.
DTC LogicINFOID:0000000003814066
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-108, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003814067
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.
