Restraint System Diagnostic Tool WarningWARNING: This tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.
Diagnosing Customer Concerns With Hard Diagnostic Trouble Codes (DTCS)
The deactivation procedure requires the disconnection of the air bag sliding contact, the passenger air bag and the side air bag floor connectors (if equipped). Restraint system diagnostic tools are attached to the vehicle harness at the air bag sliding contact and at the electrical connectors for the passenger air bag and the two side air bags (if equipped). This procedure removes the risk of air bag deployment while diagnostics are carried out. Restraint system diagnostic tools are required to carry out diagnosis and testing of the supplemental restraint system (SRS). The restraint system diagnostic tool is used to simulate air bag module connections to the system. It is not acceptable to short-circuit the air bag module connections with a zero-Ohm jumper wire. If a zero-Ohm jumper wire is used to short-circuit the air bag module connections, a lamp fault code (LFC) will be displayed.
Most supplemental restraint system (SRS) diagnostic procedures will require the use of the deactivation and reactivation procedures in this section.
WARNING: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.
The reactivation procedure requires the removal of any restraint system diagnostic tools installed and the reconnection of any air bag modules disconnected.
