Test O: LFC 41/DTC B1941 - Primary Crash Sensor Feed/Return Circuit Open

O1 - O2:

O3:

O4 - O5:

Normal Operation
The air bag Electronic Crash Sensor (ECS) monitors the resistance of the primary crash sensor circuit by measuring the resistance between Pin C200-6 and ground (C200-18 or C200-21). If the ECS detects low or high resistance, the ECS will store Diagnostic Trouble Code (DTC) B1941 in memory and flash Lamp Fault Code (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.
