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 air bag warning lamp with the SDM ground wire. This turns on the air bag 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 air bag module
• The driver air bag 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.
