Wiring Harness Connectors
If the sensing and diagnostic module (SDM) electrical connector is not attached properly, a built in shorting bar will connect the wire from airbag warning lamp with the SDM ground wire. This turns on the airbag indicator. To prevent deployment during servicing, additional shorting bars are located in following locations:
- The clock spring electrical connector at the lower steering column.
- The passenger airbag module.
- The driver airbag module.
- The seat belt pretensioners.
The shorting bar is only a backup safety device. Always disable the supplemental inflatable restraints (SIR) before beginning any service procedure.
