Inflatable Restraint Sensing And Diagnostic Module: Notes
WARNING:
Deactivate air bag system before performing any service operation involving steering column components. See appropriate AIR BAG RESTRAINT SYSTEMS article. Do not apply electrical power to any component on steering column without first deactivating air bag system. Air bag may deploy.
CAUTION:
If any water enters vehicle's interior up to level of carpet or higher and soaks carpet, Sensing And Diagnostic Module (SDM) and SDM harness connector may need to be replaced. SDM could be activated when powered, which could cause deployment of air bag(s) and result in personal injury. Before attempting these procedures, air bag system must be disabled. See appropriate AIR BAG RESTRAINT SYSTEMS article. Turn ignition switch to LOCK position, inspect SDM mounting area, including carpet. If any significant soaking or evidence of significant soaking is detected, perform following task. Remove all water. Repair water damage. Replace SDM harness connector. Replace SDM. Failure to follow these tasks could result in possible air bag deployment, personal injury, or otherwise unneeded air bag system repairs.
NOTE:
Air bag system may also be referred to as Supplemental Inflatable Restraint (SIR) or Sensing And Diagnostic Module (SDM) system.
