Hydraulic Assembly: Service and Repair

DSC HU/CM REMOVAL/INSTALLATION

Caution
^ When replacing the DSC HU/CM with a new one, configuration procedure must be performed before removing the DSC HU/CM. If configuration is not completed before removing the DSC HU/ CM, DTC B2477 will be detected.
^ The DSC may not function normally when the DSC HU/CM is replaced. After installation, always perform the initialization procedures for the DSC HU/CM, combined sensor and the steering angle sensor. (See COMBINED SENSOR INITIALIZATION PROCEDURE.) (See STEERING ANGLE SENSOR INITIALIZATION PROCEDURE.) (See STEERING ANGLE SIGNAL INITIALIZATION PROCEDURE.) Programming and Relearning Steering Angle Signal Initialization Procedure Steering Angle Sensor Initialization Procedure
^ 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. Perform DSC configuration. (See DSC CONFIGURATION.) DSC Configuration
2. Remove in the order indicated in the table.
3. Install in the reverse order of removal.
4. After installation, perform the combined sensor initialization procedure. (See COMBINED SENSOR INITIALIZATION PROCEDURE.) Steering Angle Sensor Initialization Procedure
5. After installation, perform the steering angle sensor initialization procedure. (See STEERING ANGLE SENSOR INITIALIZATION PROCEDURE.) Steering Angle Signal Initialization Procedure
6. After installation, perform the steering angle signal initialization procedure. (See STEERING ANGLE SIGNAL INITIALIZATION PROCEDURE.) Steering Angle Sensor Initialization Procedure





DSC HU/CM Connector Removal Note





1. Pull the lock lever up in the direction of the arrow.
2. Pull the connector toward the vehicle rear and remove it.

Brake Pipe Removal Note





1. Place an alignment mark on the brake pipe and DSC HU/CM
2. Apply protective tape to the connector to prevent brake fluid from entering.
3. Remove the brake pipe.

Brake Pipe (DSC HU/CM-brake pipe joint) Installation Note
1. Align with the mark made before removing the brake pipe and temporarily install the brake pipe to the DSC HU/ CM.

Caution
^ If the brake pipe is tightened to the specified torque, it may be difficult to install it to the vehicle. Therefore, only temporarily tighten the brake pipe so that it can still be moved.

Brake Pipe Installation Note





1. Align the marks made before removal and install the brake pipe to the DSC HU/CM and brake pipe joint referring to the figure.
2. Tighten the brake pipe to the specified torque using the commercially available flare nut wrench.

DSC HU/CM Connector Installation Note





1. After connecting the connector, verify that the lock lever is completely pushed in.
