Normal Operation
The air bag Electronic Crash Sensor (ECS) monitors the resistance of the primary crash sensor circuit by measuring the resistance between Pin C2041-6 and ground (C2041-18 or C2041-21). If the ECS detects low or high resistance, the ECS will store DTC B1941 in memory and flash LFC 41 (or higher priority code if one exists) on the air bag indicator.

Possible Causes
^ Damaged wiring on Circuit 619 (PK/W).
^ Damaged primary crash sensor.
