DSC HU/Cm Removal/Installation: Notes

WARNING:
  • If the DSC HU/CM configuration is not completed, it could result in an unexpected accident due to the DSC being inoperative. If the DSC HU/CM is replaced, always use the automatic configuration function so that the DSC operation conditions are correct.
  • If the DSC related parts sensor initialization procedure is not completed, the DSC will not operate properly and it might cause an unexpected accident. Therefore, after replacing or removing the DSC HU/CM, make sure to perform the DSC related parts sensor initialization procedure to insure proper DSC operation.
CAUTION:
  • The internal parts of the DSC HU/CM could be damaged if dropped. Be careful not to drop the DSC HU/CM. Replace the DSC HU/CM if it is subjected to an impact.
NOTE:
  • When the ignition is switched to ON or the engine is started after the DSC HU/CM have been replaced, the DSC CM reads data from the instrument cluster via CAN communication to perform automatic configuration.
  • The DSC HU/CM prior to replacement stores the vehicle specification information.
  • A new DSC HU/CM does not store any vehicle specification information.
