CAUTION: When performing service on or around SIR components or SIR wiring, follow the procedures listed below to temporarily disable the SIR system. Failure to follow procedures could result In possible air bag deployment, personal Injury, or otherwise unneeded SIR system repairs.
CAUTION: The SDM can maintain sufficient voltage to cause a deployment for up to 10 seconds after the ignition switch Is turned "OFF", the battery Is disconnected, or the fuse powering the 5DM is removed. Many of the service procedures require removal of the "AIR BAG #1" fuse and disconnection of the deployment loops to avoid an accidental deployment.
Important: Before doing any service procedures in this section, disabling the SIR system and removal of Inflator Module and Steering Wheel is needed. Columns equipped with Supplemental Inflatable Restraint (SIR) and Redundant Steering Wheel Control (RSWC) will have Inflatable Restraint coils with two wire leads. (SIR) wire leads are yellow with a yellow connector shroud. (RSWC) wire leads are grey with black connectors.
