Description

INFOID:0000000007356555

DTC B1209 - B1211 COLLISION DETECTION

The air bag diagnosis sensor unit will set this DTC if it has detected a collision or rollover which has resulted in

a deployment of one or more air bags or pre-tensioners.  If this DTC is detected after a SRS repair, the air bag

diagnosis sensor unit has not yet been replaced.  This DTC can not be erased.
