C: LFC 19/DTC B1231 - Crash Data Memory Full
Normal OperationWARNING:
- THE AIR BAG ELECTRONIC CRASH SENSOR (ECS) ORIENTATION IS CRITICAL FOR CORRECT SYSTEM OPERATION. IF A VEHICLE EQUIPPED WITH AN AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) HAS BEEN INVOLVED IN A COLLISION IN WHICH THE CENTER TUNNEL AREA HAS BEEN DAMAGED, INSPECT THE MOUNTING AND BRACKET FOR DEFORMATION. IF DAMAGED, THE ECS MUST BE REPLACE WHETHER OR NOT THE AIR BAGS HAVE DEPLOYED. IN ADDITION, MAKE SURE THE AREA OF THE ECS MOUNTING IS RESTORED TO ITS ORIGINAL CONDITION.
- CLEARING DTC B1231 WILL POTENTIALLY REMOVE ALL RECORDS OF THE CRASH EVENT.
When the air bags are deployed during a collision, the air bag Electronic Crash Sensor (ECS) module will flash a Lamp Fault Code (LFC) 19 on the air bag indicator and store a Diagnostic Trouble Code (DTC) B1231 in memory. The LFC 19 and DTC B 1231 indicate that a crash has been recorded by the ECS.
Possible Cause
Crash data memory full is caused by:
- a crash event which deployed the air bags.
