Technician Safety Information
CAUTION: When you are performing service on or near the SIR components or the SIR wiring, you must disable the SIR system. Refer to Disabling the SIR System under Air Bag(s) Arming and Disarming. Failure to follow the correct procedure could cause air bag deployment, personal injury, or unnecessary SIR system repairs.The Inflatable Restraint Sensing And Diagnostic Module (SDM) maintains a reserved energy supply. The reserved energy supply provides deployment power for the air bags. Deployment power is available for as much as 1 minute after disconnecting the vehicle power. Disabling the SIR system prevents deployment of the air bags from the reserved energy supply.
CAUTION:
^ In order to avoid deploying the air bag when troubleshooting the SIR system, use only the equipment specified and the instructions given in these procedures. Failure to use the specified equipment as instructed could cause air bag deployment, personal injury to you or someone else, or unnecessary SIR system repairs.
^ It 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 under Air Bag(s) Arming and Disarming.
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 SIR system repairs.
