(Initialization fault)

SDM internal fault

Notice

• Use only the scan tool to check the airbag module and the sensing and diagnostic module (SDM). Never

measure the resistance of an airbag module with an ohmmeter. An ohmmeter’s battery can deploy the
airbag and cause injury.

• Before testing, disconnect the negative battery cable. Wait 1 minute for the SDM capacitor to discharge. The

capacitor supplies reserve power to deploy the airbags, even if the battery is disconnected. Unintentional
deployment of the airbags can cause injury.

• Do not attempt to repair the supplemental inflatable restraints (SIR) wiring harness. An SIR repair can create a

high-resistance connection which can keep the airbags from deploying when needed, resulting in injury.
