With Hard DTCs/ Lamp Fault Codes

DIAGNOSING CUSTOMER CONCERNS WITH HARD DTCs

All Supplemental Restraint System (SRS) diagnostic procedures will require deactivation and reactivation of the system. Deactivation and reactivation require the disconnection of most SRS components and the installation of restraint system diagnostic tools. This reduces the risk of inadvertent deployment of SRS components while diagnostic procedures 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.
