Wait at least one minute after disconnecting the battery ground cable(s) before commencing any repair or adjustment to the supplemental restraint system (SRS), or any component(s) adjacent to the SRS sensors. Failure to follow these instructions may result in personal injury. NOTE:Following the pinpoint tests when a diagnostic trouble code/lamp fault code (DTC/LFC) is not present, or the air bag warning indicator is not permanently illuminated, will result in needless replacement of air bag system components and repeat repairs. Speak with the customer to determine if a particular set of conditions must be met in order for a fault to occur. If a LFC is reported by the customer but is not present when the vehicle comes in for repair, pinpoint test diagnostics cannot be used. Instruct the customer on how to count an LFC. Diagnosing Customer Concerns with Hard DTCs/LFCs WARNING:Do not use substitute air bag simulators when working on the SRS. Use only the appropriate tool. Failure to follow this instruction may result in personal injury. Most air bag system diagnostic procedures require the use of system deactivation and system reactivation procedures. These procedures require the air bag module(s) and safety belt pretensioners to be disconnected from the SRS, thereby removing the risk of an air bag deployment while diagnostics are carried out. Air bag simulators are required to carry out diagnosis and testing of the air bag system. The simulator contains a resistor, used to simulate an air bag module connection to the system. It is not acceptable to short-circuit the air bag module connections with a 0 ohm jumper wire. If a 0 ohm jumper wire is used to short-circuit the air bag module connections, a LFC will be displayed and a DTC logged by the air bag control module. Deactivation WARNING:To avoid accidental deployment, the air bag control module back up power supply must be depleted. Wait at least one minute after disconnecting the battery ground cable(s) before commencing any repair or adjustment to the SRS, or any component(s) adjacent to the SRS sensors. Failure to follow these instructions may result in personal injury. - Disconnect the battery ground cable.
REFER to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures). - Wait at least one minute for the backup power supply in the air bag control module to deplete its stored energy.
WARNING:Place the air bag module(s) on a ground wired bench, with the trim cover facing up to avoid accidental deployment. Failure to follow this instruction may result in personal injury. -
