REMOVAL AND INSTALLATION



warning
  • Never connect the negative battery terminal when the SRS-ECU is not installed securely. If you fail to follow this instruction, the air bag may deploy unintentionally, possibly causing a serious injury.
caution
  • Disconnect the negative (-) battery terminal and wait for 60 seconds or more before starting work. Insulate the disconnected (-) terminal by wrapping the tape (Refer to the item 5 of Service Precautions ).
  • Never attempt to disassemble or repair SRS-ECU. If damaged, replace with a new SRS-ECU.
  • Do not drop or subject SRS-ECU to impact or vibration. If denting, cracking, deformation, or rust is discovered in SRS-ECU, replace it with a new one.
  • After deployment of the air bags, replace SRS-ECU with a new one.
  • When the SRS-ECU is replaced, chassis number writing and coding must be performed. Perform the coding when SRS-ECU sets diagnosis code No. U1195 (coding incomplete). Refer to the "M.U.T.-III operation manual" and perform coding.
Pre-removal operation
  • Turn the ignition switch to the LOCK (OFF) position.
  • Disconnect the negative (-) battery terminal.
