Normal Operation
The air bag Electronic Crash Sensor (ECS) module supports features that are not used in these vehicles. The wiring harness pins used by the ECS for these features are normally left disconnected. If the ECS detects a connection to Pin 6, 24, 25, 26 or 27 it will store a Diagnostic Trouble Code (DTC) B1885, B1886, B1901 or B1941 in memory and flash a Lamp Fault Code (LFC) 14, 41, 46 or 47.

Possible Causes
An unexpected feature present could be caused by:
^ wiring harness fault causing connection to a normally unused ECS pin.
^ internal ECS module fault.
