Correction
Caution:
In order to avoid deploying the air bag when troubleshooting the SIR system, use only the equipment specified in this bulletin and the instructions
given in this bulletin. 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.
Caution:
If any water has entered the vehicle's interior up to the level of the carpet or higher and soaks the carpet, the sensing and diagnostic module (8DM)
and the 8DM harness connector may need to be replaced. The 8DM 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.
Important:
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 steps:
1.
Determine the reason, and repair if needed, the path that allowed the water to enter the vehicle.
2.
Remove all water.
3.
Repair any water damage.
4.
Replace the SDM harness connector terminals if corrosion is evident.
5.
Replace the SDM.
Failure to follow these steps could result in possible air bag deployment, personal injury, or otherwise unneeded SIR system repairs.
