With Hard DTCs/ Lamp Fault Codes

Most air bag Supplemental Restraint System (SRS) diagnostic procedures will require deactivation and reactivation of the SRS. Deactivation and reactivation require the installation and removal of restraint system diagnostic tools. These procedures require the disconnection of the driver and passenger front and, if equipped, driver and passenger side air bag modules, and the disconnection of the driver and passenger safety belt pretensioners. 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 for the diagnosis and testing of the 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.
