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.

1. Disconnect the DSC HU/CM connector. (See 04-15-6 DSC HU/CM REMOVAL/INSTALLATION.)
2. Connect the negative battery cable. (See 01-17-2 BATTERY REMOVAL/INSTALLATION[L3 WITH TC].)
3. Attach the tester lead to the DSC HU/CM harness side connector, then inspect voltage, continuity or resistance

according to the standard (reference value) on the table.
