With Hard Diagnostic Trouble Codes (DTC)/Lamp Fault Codes (LFC)

Most air bag Supplemental Restraint System (SRS) diagnostic procedures will require the use of the deactivation and reactivation procedures.

The deactivation and reactivation require the installation and removal of restraint system diagnostic tools. These procedures require removal of driver air bag module, and the disconnection of the passenger air bag module, driver side air bag module, passenger side air bag module, driver safety belt retractor pretensioner, and passenger safety belt retractor pretensioner. This reduces the risk of deployment of air bag modules and safety belt pretensioners while diagnostics are being carried out.

Restraint system diagnostic tools are required to carry out diagnosis and testing of the Supplemental Restraint System (SRS). It is not acceptable to short-circuit the air bag module connections with a jumper wire. If a jumper wire is used to short-circuit the air bag module connections, a Lamp Fault Code (LFC) will be displayed.
