Air bag warning light on momentally
I have a 2004 xj8 with 50K miles. The air bags warning light is on from time to time. I think there might be a loose wire somewhere.
Please pint me to where I can get a air bags wire schematic so I can track down al the wire harness plugs.
I did not paid attention to how many flashes since the wife did all the driving. The light never comes on when I drove it. Go figure.

Hi annamiata,
As you hinted, the flash codes would be the fastest way to diagnose the problem, assuming a fault code has been stored. The light doesn't automatically display a flash code. You have to follow the instructions that begin on page 608 of the Body section of the Workshop Manual, which you can download here:

The flash codes are all associated with a Diagnostic Trouble Code (DTC) with a B-prefix (Body). You can look up additional information in the DTC Summaries manual, which you can download here:
https://www.google.com/url?sa=t&rct=...03388427,d.cWw
The component locations are given in the Electrical Guide available at the link Sean provided. Some possible suspects include looseness of or corrosion on an electrical connector, issues with the front seat belt buckle switches or the passenger seat weight pressure switch or module, etc.
Please let us know what you discover!
Cheers,
Don

My wife finally video recorded the airbag warning light when it was on. It flashed two blinks paused, and two blinks again. It repeated several times and the airbag warning light stayed on permanently.
I am counting as code 22
Jaguar technical bulletin indicates
Driver side air bag fault lower resistance or open circuit, or short to ground, or short to battery
Possible cause =
Connector: FC009, SD013, SD015. Driver side air bag.
Harnesses: Driver seat, Instrument panel
It happened only when my wife drove the Jag. I just found the fault code tonight and will do further investigating this weekend.

No matter how many times I drove the Jag, no airbag warning light came on except when my petite (5'4") wife drove it.... and I realized that she sat too closed to the steering wheel and occasional set the air bag light. I show her how to re adjust seat, steering column, brake and acelate column. I will see if the air bag light will come on.
