DSC HU/CM REMOVAL/INSTALLATION [R.H.D.]

id0415008010b5

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.

•  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.

Note

•  When the ignition switch is turned to the ON position 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 battery, battery tray and battery tray bracket. (ZJ, ZY) (See BATTERY REMOVAL/INSTALLATION [ZJ, ZY].)

2.  Remove the battery and battery tray. (MZ-CD 1.6 (Y6)) (See BATTERY REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6)].)

3.  Remove in the order indicated in the table.

4.  Install in the reverse order of removal.

5.  Add brake fluid, bleed the brakes, and inspect for leakage after the installation has been completed. (See AIR BLEEDING.)

6.  Turn the ignition switch to the ON position or start the engine, and maintain this condition for approx. 30 s to allow the DSC HU/CM automatic configuration to be performed.

7.  Perform the initialization procedures for the combined sensor, brake fluid pressure sensor. (See DSC SENSOR INITIALIZATION PROCEDURE.)

8.  Perform the DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)

2.  Pull the connector toward the vehicle front and remove it.

Caution

•  If sand or other particles get into the connector cover, it may be difficult to remove. In order not to damage the connector, be careful not to use excessive force removing the cover.

Brake Pipe Removal Note

1.  Place an alignment mark on the brake pipe and DSC HU/CM.

2.  Affix protective tape to the connector to prevent brake fluid from entering.

3.  Remove the brake pipe.

4.  Adhere protective tape to the installation area of the DSC HU/CM brake pipe to prevent foreign material penetration.

Brake Pipe Installation Note

1.  Align the marks made before removal and install the brake pipe into the DSC HU/CM referring to the figure.
