Fault Code 12
Air Bag Deployment Circuit Drop in Battery Voltage
Circuit Description
Normal Operation
The diagnostic monitor measures the voltage at pin 13 of the diagnostic monitor connector. Voltage at pin 13 should be equal to battery voltage. If the voltage measured at pin 13 drops to less than 9 volts, the diagnostic monitor will flash out code 12.
Possible Causes
A drop in battery voltage at diagnostic monitor pin 13 can be caused by:
1.An open circuit that would prevent battery voltage from reaching diagnostic monitor pin 13.
NOTE:
If the instrument panel fuse and/or the power distribution fuse are blown, be sure to diagnose the system for possible causes 2 and 3 below.
2.A short to ground in Circuit 611 (W/O) or 612 (P/O) may result in a blown instrument panel fuse and/or power distribution fuse.
3.An internal short to ground within the safing sensor may result in a blown instrument panel fuse and/or power distribution fuse.
4.A problem in the charging system causing battery voltage to drop below 9 volts.
Testimonial: "thank u this was an informative answer as 12 volts do not reach pin13, as soon as a fuse is installed in fuse location 10 instrument panel it blows i read allmost no resistance to ground so items 2 or 3 seem plausable now if i could find Circuit 611 (W/O) or 612 (P/O) and or be able to test the air bag diagnostic monitor which houses the safing sencor hmmm"
6 ohms to ground on non power side of fuse, where do i go from here???? What are you checking the ground side for ???? You have a short to ground on the power side .
Here you go , you better study up on electrical testing .

Lost battery feed or low battery feed voltage
GO to DTC B1867.

Testimonial: "sorry jeff maybe i wasnt clear on what i did i measured 6 ohms at first then less than 1 ohm on the output side of the fuse plug with oput a fuse in telling me that there is a short some where, fuse 10 on the vic is allways hot and the fuse blows even when the key is off. so i was asking where or what does the line from the fuse acually feed"
SOURCE: i need a diagram for a 1998 ford crown vic interior fuse box
ITS FUSE #16 AND ITS a 20A FUSE
SOURCE: 2001 crown vic keeps burning 30A PCM relay fuse
have fuel pump checked i have known a bad fuel pump shorting out causing pcm fuse to blow.
SOURCE: air bag light is on
When the light comes on, it means there's a problem with the airbag system itself. You can't just turn the light off because the system is telling you that the airbag most likely will not deploy when needed. You should have a mechanic look into this....
SOURCE: 2005 Crown Vic climat contr fan not working Fuses good Motor good
does it have a digital control panel? As this uses an electronic blower speed controller located at the engine compartment (rear engine block) fix on ac phlenum try to shake the connector or wire while the system is on.
SOURCE: working on a 2000 crown
okay to make it simole for you......bank 1 is the bank where number 1 cyl. is located,so in your case you need to go to opposite side of number 1 cyl that being bank 2,sensor one will be the first on in the exhaust stream,if you need more let me know. have a good day
