Description
INFOID:0000000009882919
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.
