DSC HU/Cm Removal/Installation: Notes

CAUTION:
  • Always use the adapter that comes with a new DSC HU or DSC CM when separating the DSC HU or DSC CM. Otherwise, the pump motor may come off the DSC HU and be damaged. Therefore, do not separate the DSC HU and DSC CM unless replacing them. When replacing them with new ones, always perform procedures according to the instructions included with the new parts.
  • 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.
  • 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 or DSC CM is replaced, always use the automatic configuration function so that the DSC operation conditions are correct.
  • If the DSC 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 sensor initialization procedure to insure proper DSC operation.
NOTE:
  • When the ignition is switched to ON or the engine is started after the DSC HU/CM or DSC CM has been replaced, the DSC CM reads data from the instrument cluster via CAN communication to perform automatic configuration.
  1. Remove the installation nut for the cooler hose (LO) bracket and set the cooler hose (LO) aside. (See REFRIGERANT LINE REMOVAL/INSTALLATION .)
  2. Remove in the order indicated in the table.
  3. Install in the reverse order of removal.
  4. Add brake fluid, bleed the brakes, and inspect for leakage after the installation has been completed. (See BRAKE FLUID AIR BLEEDING .)
  5. Switch the ignition to ON or start the engine, and maintain this condition for approx. 30 s  to allow the DSC HU/CM automatic configuration to be performed.
