DSC HU/Cm Removal/Installation: Notes
CAUTION:
- 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.
- 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.
- Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [LF, L3] .) (See BATTERY REMOVAL/INSTALLATION [L3 WITH TC] .)
- Remove the reserve hose (MTX vehicles). (See MASTER CYLINDER REMOVAL/INSTALLATION [L3 WITH TC] .) (See CLUTCH MASTER CYLINDER REMOVAL/INSTALLATION .)
- Remove in the order indicated in the table.
- Install in the reverse order of removal.
- Configurate the DSC HU/CM (only when replacing it). (See DSC CONFIGURATION ).
- Perform the initialization procedures for the combined sensor, brake fluid pressure sensor. (See COMBINED SENSOR INITIALIZATION PROCEDURE ). (See BRAKE FLUID PRESSURE SENSOR INITIALIZATION PROCEDURE ).
- Clear the DTCs from the memory. (See
ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)]
.)NOTE:
- Even if the initialization procedure is performed after replacing the DSC HU/CM, DTCs B2141 and C2785 are stored in the memory as past malfunctions.
