Note: If any water enters the vehicle 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 SRS system must be disabled. Refer to Disabling the SRS 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.
Carefully follow these tasks to ensure personal safety, avoid air bags deployment or unneeded SRS system repairs.
- If the floor carpet is wet, refer to Floor Carpet Drying .
- Remove the trim mouldings or the headlining assembly in order to repair the leak, if needed. Refer to interior trim and panelling section, for appropriate procedures.
- Determine the source of water entry.
- If water is leaking at the edge of the windscreen, reseal the windscreen using a GM approved Urethane Adhesive Caulking Kit
- If water leaks into the vehicle at the sides of the stationary windows, reseal the window using a GM approved Urethane Adhesive Caulking Kit.
