B1210 SIDE COLLISION DETECTION

Description

INFOID:0000000001069915

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.
