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 the AIRBAG warning lamp with the SDM ground wire. This turns on the AIRBAG lamp.

To prevent deployment during servicing, additional shorting bars are located in the following locations:
- The clockspring electrical connector at the lower steering column.
- The passenger airbag electrical connector.
- The driver airbag module.

The shorting bars are only a backup safety device. Always disable the Supplemental Inflatable Restraints (SIR) system before beginning any service procedure.
