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:
- Remove all water.
- Repair the water damage.
- Replace the SDM harness connector.
- Replace the SDM.
Failure to follow these tasks could result in possible air
bag deployment, personal injury, or otherwise unneeded SIR system repairs.
- If the floor carpet is wet refer to
Floor Carpet Drying.
- Remove the trim moldings or the headliner in order to repair the leak,
if needed.
- Determine the source of water entry.
- If water is leaking at the edge of the windshield, reseal the windshield
using Urethane Adhesive Caulking Kit GM P/N 12346392 or the equivalent.
- If water leaks into the vehicle at the sides of the stationary windows,
reseal the window using Urethane Adhesive Caulking Kit GM P/N 12346392
or the equivalent.
