Airbag Code B1942 HELP!

:frown: 1996 Windstar W/ 158000km I have a Airbag code B1942 LH Primary Crash Sensor Feed Return Circuit Open. I have replaced the sensor but still have a Airbag light, and unable to clear code. Does anybody have any ideas that wont cost an arm or a leg? I also have a sweet smell in the cab in the morning while warming up, is this a heater core problem? and if so how hard to fix

The "sweet smell" is a classic sign of a leaking heater core (or leaking hose that attaches to a heater core). You're smelling the engine coolant.

Reliably tracking down the airbag code will require using a decent multimeter. You may have replaced the sensor - but is the electrical connection really being made? The meter can tell you this, with the help of some good service information.

Hi
looking at my '96 manual, it indicates that "should a fault occur which could cause inadvertent deployment of the air bags, the diagnostic module will open this fuse to disarm the system". The fuse in question is fuse "U" in the engine compartment fuse box. You might check it, and if o.k., remove it then put it back into place. I would do this with nobody in the car.

I would be careful about poking around in the wiring as I would be concerned about firing the bags. If you remove both battery leads and wait a few minutes the system should be safe for dis-assembly if required.
