Battery Disconnect/Connect Procedures

WARNING: The backup power supply energy must be depleted before any supplementary restraint system repairs are carried out. To deplete the backup supply energy, first disconnect the battery ground cable, then disconnect the battery positive cable and wait ten minutes to avoid accidental deployment and personal injury. Failure to follow this instruction may result in personal injury.

CAUTION: Disconnecting the battery cables will cause all of the electronic control modules to lose all stored data/fault codes.
