Because of the history of trouble with this circuitry in other '03 CTSs, I'd check the airbag and SMD wiring inch by inch for starters. A broken/pinched wire or corroded connector would give you the same symptoms and can be fixed for nothing but labor. Why swap parts and find out it still doesn't work and still have to fix the wiring?

I don't know if this helps, but I had the "service the air bag" come on about a year ago. It turned out to be a bad air bag module under the passenger seat. The dealership wanted about $800 to replace parts and labor, but I had a warranty. good luck

It's an expensive and difficult repair. Welcome to luxury car ownership. If you want to dance, you have to pay the piper.

First of all... if that is the way it is really written on the RO I'd be tempted to find another dealership.
If those are type-o's then you are both forgiven.

That bulletin (TSB) does put 2 and 2 together and it would seem based on the information that I can translate out of that the vehicle may need an "SDM" (not SMD) and a sensor as the tech indicated.

#02-09-41-003: Air Bag Indicator Illuminates Intermittently, IPC and Sensing and Diagnostic Module (SDM) DTC U1000 Set (Replace Front End Sensor Assembly and/or Sensing Diagnostic Module) - (Oct 14, 2002)


Subject: Air Bag indicator Illuminates Intermittently, IPC and Sensing and Diagnostic Module (SDM) DTC U1000 Set, OnStar® System DTC U1088 Set (Replace Front End Sensor Assembly and/or Sensing Diagnostic Module)


Models: 2002-2003 Cadillac DeVille Built Prior To VIN Breakpoint 3U159084

2003 Cadillac CTS Built Prior To VIN Breakpoint 30131856




--------------------------------------------------------------------------------

Condition
Some customers may comment that after starting the vehicle, the Air Bag Readiness Light/Indicator on the instrument panel cluster (IPC) flashes for a few seconds (6-10 times) and then remains illuminated until the next ignition cycle.

Technicians may find a SDM and IPC U1000 DTC and an OnStar® System U1088 DTC set in history.

Cause
This condition may be due to a unique Class 2 communication software issue within the Sensing and Diagnostic Module (SDM).

Correction
Use the scan tool to:
• Perform the standard SIR diagnostic system check in order to verify the condition. Refer to Diagnostic System Check-SIR in the SIR sub-section of the appropriate Service Manual.

• Obtain the part number of the existing SDM.

On CTS models only, obtain the part number of the existing inflatable restraint front end sensor.
If the scan tool displays DTCs U1000 and U1088 and the existing SDM part number is NOT listed in the Parts Information table in this bulletin, go to Step 5 for DeVille and Step 6 for CTS.
If the scan tool does NOT display DTCs U1000 and U1088, perform the diagnostic procedure as indicated in the Diagnostic System Check-SIR in the Service Manual.
For DeVille models, replace the SDM only. Refer to the Inflatable Restraint Sensing and Diagnostic Module Replacement procedures in the SIR sub-section of the Service Manual.
For CTS models:
• Replace the SDM. Refer to the Inflatable Restraint Sensing and Diagnostic Module Replacement procedures in the SIR sub-section of the Service Manual.

• If the existing front end sensor is NOT P/N 25744736, replace it with P/N 25744736. Refer to the Inflatable Restraint Front End Sensor Replacement procedures in the SIR sub-section of the Service Manual.
