Test C: LFC 19/DTC B1231 -Crash Data Memory Full

C1 - C3:

Normal Operation

WARNING:
^ THE ELECTRONIC CRASH SENSOR (ECS) MODULE ORIENTATION IS CRITICAL FOR PROPER 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 MODULE SHOULD BE REPLACED. IN ADDITION, MAKE SURE THE AREA OF THE ECS MODULE MOUNTING IS RESTORED TO ITS ORIGINAL CONDITION.
^ THE ECS MODULE MUST BE REPLACED IF THE AIR BAG MODULES HAVE DEPLOYED.
^ 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 B1231 indicate that a crash has been recorded by the ECS.

Possible Causes
Crash data memory full is caused by a crash event that deployed the air bags.
