With Hard DTCs/ Lamp Fault Codes
DIAGNOSING CUSTOMER CONCERNS WITH HARD DIAGNOSTIC TROUBLE CODESMost air bag supplemental restraint system (SRS) diagnostic procedures will require the use of the deactivation and reactivation procedures. These procedures require the removal of the driver air bag module and disconnection of the passenger air bag module and the installation of restraint system diagnostic tools. This reduces the risk of inadvertent deployment of the SRS components while diagnostic procedures are carried out.
Restraint system diagnostic tools are required to carry out 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.
