警告
Make sure 12V/LV power has been disconnected for at least 1 minute before disconnecting the electrical harness from Supplementary Restraint System (SRS) components, such as Restraint Control Module, sensors, airbags, etc. Disconnect the 12V/LV battery and the First Responder Loop. Failure to do so can result in unintended safety system behaviors. For more information on SRS precautions, see 气囊和辅助约束系统 (SRS) 预防措施.
