B1209 – B1210 COLLISION DETECTION

Description

INFOID:0000000004528719

DTC B1209 - B1210 COLLISION DETECTION

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

or side 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.  If the air bag diagnosis

sensor unit detects a frontal collision, it will send an air bag deployment signal to the hybrid vehicle control

ECU.  The hybrid vehicle control ECU will then shut down the entire high voltage power supply.
