id041500801000

Warning
•  When replacing the DSC HU/CM, the configuration procedure must be done before removing the DSC HU/CM. If the configuration is not completed before removing the DSC HU/CM, DSC will not work properly after installation of the DSC HU/CM.
•  If the DSC sensor initialization for a MTX vehicle is not completed, the Hill Launch Assist (HLA) will not operate properly and could cause an accident. Therefore, after replacing or removing the DSC HU/CM or SAS control module, make sure to perform the DSC sensor initialization to assure proper Hill Launch Assist (HLA) 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.

1.  Remove in the order indicated in the table.

2.  Install in the reverse order of removal.

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

4.  Configurate the DSC HU/CM (only when replacing it). (See DSC CONFIGURATION.)

5.  Perform the initialization procedures for the low-G (XY) sensor. (MTX) (See DSC SENSOR INITIALIZATION PROCEDURE.)

6.  Clear the DTCs from the memory. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
