PINPOINT TEST M: LFC 41/DTC B1941 - PRIMARY CRASH SENSOR FEED/RETURN CIRCUIT OPENTest M1-M3:
Test M4-M5:
Normal Operation
The air bag Electronic Crash Sensor (ECS) monitors the resistance of the primary crash sensor circuit by measuring the resistance between Pin C2209-6 and ground (C2209-18 or C2209-21). 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.
