Any measurable resistance between the inflater module wires can cause a slight electrical leakage and set a B1000. Disable the air bags then consult a wiring diagram. Check the wires to the front end discriminating sensors for a short to ground. Check the steering wheel inflater module circuits for a short and check the passenger's inflater module circuits for a short to ground. Disconnect the SDM and the driver's side and passenger side inflater modules. Using a Digital Volt Ohm Meter (DVOM), check for any resistance between the 2 wires to each air bag.If ANY resistance is measured, inspect the harness under the seats for contamination from water or salt. If no resistance replace SDM which is located under the center console, here is a picture.
Ok, you should be able to get at it without removing the seat......But sometimes its easier just to spend another 20 minutes removing seat so you dont need to work wrench around things. Here is a wire diagram, let me know if you have questions. Thanks.
