B1209 – B1211 COLLISION DETECTION

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.

DIAGNOSTIC CODE CHART

NOTE:

Follow the procedures in numerical order when repairing malfunctioning parts. Confirm whether malfunction is

eliminated using air bag warning lamp or CONSULT each time repair is finished. If malfunction is still

observed, proceed to the next step. When malfunction is eliminated, further repair work is not required.
