For 1990-2009 cars

Caution: If any water enters the vehicle's interior up to the level of the carpet or higher and soaks the carpet, the sensing and diagnostic module (SDM) and the SDM harness connector may need to be replaced. The SDM could be activated when powered, which could cause deployment of the air bag(s) and result in personal injury. Before attempting these procedures, the SIR system must be disabled. Refer to Disabling the SIR System.

With the ignition OFF, inspect the SDM mounting area, including the carpet. If any significant soaking or evidence of significant soaking is detected, you must perform the following tasks:

1. Remove all water.
2. Repair the water damage.
3. Replace the SDM harness connector.
4. Replace the SDM.

Failure to follow these tasks could result in possible air bag deployment, personal injury, or otherwise unneeded SIR system repairs.

Some interior components may need to be removed to repair the leakage, according to water leakage position.

1. If the carpet is soaked, refer to Floor Carpet Drying .
2. Cut off part of the adhesive agent from inside or outside the vehicle in the leakage area.
3. Clean and remove all loose particles of the old adhesives from the area.
4. Apply body and seam sealant to where the old adhesive caulking was removed.
5. Allow the seam adhesives to dry for several hours.
6. Test for leakage.
7. Install the trim (if removed).
