2. Remove the battery tray bracket as shown in the 

figure.

3. Remove in the order indicated in the table.
4. Install in the reverse order of removal.
5. After installation, add brake fluid, bleed the air, 

and inspect for fluid leakage. (See 04-11-3 AIR 
BLEEDING.)

6. After installation, perform the combined sensor 

initialization procedure. (See 04-15-17 
COMBINED SENSOR INITIALIZATION 
PROCEDURE.)

7. After installation, perform the steering angle 

sensor initialization procedure. (See 09-40-8 
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.

DSC HU/CM Installation Note

1. Install the rubber mount on DSC HU/CM section 

A to the bracket as shown in the figure.

2. Install DSC HU/CM section B to the bracket.
3. Install the nuts to DSC HU/CM section A and 

tighten them.

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 SST (49 0259 770B) and the 
commercially available flare nut wrench.
