    Important: 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 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:

    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 SRS system repairs.

  1. If the floor carpet is wet, refer to Floor Carpet Drying in Interior Trim.
  2. Remove the trim moldings or the headlining assembly in order to repair the leak, if needed. Refer to Section 8 Interior Trim, for appropriate procedures.
  3. Determine the source of water entry.
  4. If water is leaking at the edge of the windscreen, reseal the windscreen using a Holden approved Urethane Adhesive Caulking Kit
  5. If water leaks into the vehicle at the sides of the stationary windows, reseal the window using a Holden approved Urethane Adhesive Caulking Kit.
