Description

INFOID:0000000000959759

DTC B1210 SIDE COLLISION DETECTION

If the components that are not activated in side collision are reused, they should be checked for damage by
CONSULT-lll or air bag warning lamp. Repair or replace the malfunctioning parts.

OPERATION

The side air bag and curtain air bag are operated by the decision of the diagnosis sensor unit (ACU) signal of
the side collision.

STRUCTURE

It consists of satellite sensor, diagnosis sensor unit (ACU), side air bag and curtain air bag. 

INSTALLATION

DIAGNOSTIC PROCEDURE

1.

CHECK FOR SIDE “AIR BAG”

Check the side air bag.

Is the side “AIR BAG” module deployed?

YES

>> Replace side “”

NO

>> Replace, if there are any malfunction signs checking with CONSULT-lll.

2.

CHECK FOR CURTAIN "AIR BAG".

Check the curtain air bag.

Is the “AIR BAG” module activated?

YES

>> Replace side curtain “AIR BAG”.

NO

>> Replace, if there are any malfunction signs checking with CONSULT-lll.

3.

CHECK FOR SATELLITE SENSOR

Check the satellite sensor.
Is the side “AIR BAG” module and/or side curtain “AIR BAG” module activated?

YES

>> Replace satellite sensor.

NO

>> Replace, if there are any malfunction signs checking with CONSULT-lll.

4.

CHECK FOR DIAGNOSIS SENSOR UNIT

Check the diagnosis sensor unit.

Is the side “AIR BAG” module and/or side curtain “AIR BAG” module activated?

YES

>> Replace diagnosis sensor unit (ACU).

NO

>> Replace, if there are any malfunction signs checking with CONSULT-lll.

5.

CHECK FOR “SEAT BELT” PRE-TENSIONER

Check the seat belt pre-tensioner.

Is the seat belt able to extend smoothly any visible signs of damage?

YES

>> Replace, if there are any malfunction signs checking with CONSULT-lll.

NO

>> Replace “SEAT BELT” pre-tensioner.
