To avoid deployment when servicing the SIR system or components in the immediate area, do not use electrical test equipment such as battery or A.C. powered voltmeters, ohmmeters, etc. or any type of tester other than specified. Do not use a non-powered probe tester. To avoid personal injury, all precautions must be strictly adhered to.
Never disconnect any electrical connection with the ignition switch
unless instructed to do so in a test.
Before disconnecting the negative battery cable, make a record of the contents memorized by each memory system like the clock, audio, etc. When service or repairs are completed, make certain to reset these memory systems.
Always wear a grounded wrist static strap when servicing any control module or component labeled with a Electrostatic Discharge (ESD) sensitive device symbol.
Avoid touching module connector pins.
Leave new components and modules in the shipping package until ready to install them.
Always touch a vehicle ground after sliding across a vehicle seat or walking across vinyl or carpeted floors to avoid static charge damage.
The DERM can maintain sufficient voltage to cause a deployment for up to 10 minutes, even if the battery is disconnected.
Never strike or jar a sensor, or deployment could happen.
Never power up the SIR system when any sensor is not rigidly attached to the vehicle.
Always carry an inflator module with the trim cover pointed away.
Always place an inflator module on the workbench with the trim cover up, away from loose objects.
The inflator module is to be stored and shipped under DOT flammable solid regulations.
The inflator module must be deployed before it is scrapped.
After deployment, the air bag surface may contain sodium hydroxide dust. Always wear gloves and safety glasses when handling the assembly. Wash hands with mild soap and water afterwards.
Any visible damage to the sensors requires component replacement.
Wire and connector repair must be performed using kit J-38125, or equivalent. Use special crimping tools, heat torch and seals.
Absolutely no wire connector, or terminal repair is to be attempted on the arming sensor, passenger compartment discriminating sensor, forward discriminating sensor, inflator module or SIR coil assembly.
Never bake dry paint on vehicle or allow to exceed temperatures over 300°F, without disabling the SIR system and removing the inflator module.
Do not interchange sensors between models or years.
Do not install used SIR system parts from another vehicle.
Make certain when installing the SIR wiring harness, the wires are not pinched or interfering with any of the other vehicle parts.
Make certain all SIR grounds are clean and securely fastened for maximum metal-to-metal contact.
Orange color double-lock type connectors are used. When disconnecting the connectors, unlock them at both inside and outside. When installing, insert the connector completely and lock at the outside.
Never allow welding cables to lay on, near or across any vehicle electrical wiring.
