  Caution

  • The DSC may not function normally immediately after the DSC HU/CM is replaced. After installation, always perform the initialization procedures for the combined sensor, brake fluid pressure sensor.
  • 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.

1. Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [ZJ, Z6].) (See BATTERY REMOVAL/INSTALLATION [LF].)

2. For L.H.D., remove the reserve hose (MTX vehicles). (See Reserve Hose Removal Note.) (See Clutch Pipe and Clutch Reserve Hose Removal Note.) (See Reserve Hose Installation Note.) (See Clutch Pipe and Clutch Reserve Hose Installation Note.)
