Description

INFOID:0000000003367517

DTC B1202, B1203, B1204, B1205, B1206, B1207 DIAGNOSIS SENSOR UNIT

Detects the whole SRS electrical system 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 electro-diagnosis tester CONSULT-III.

OPERATION

It detects a shock that exceeds specified level and monitors such systems as the driver and passenger air
bag, side air bag, curtain air bag, pre-tensioner seat belts and Occupant Classification System (OCS) operate
properly. 

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.
