REMOVAL SERVICE POINT

.

<<A>> HYDRAULIC UNIT (ASC-ECU) REMOVAL

CAUTION

• Be careful when removing the hydraulic unit because it 

is heavy.

• Never loosen the nuts and the bolts because the 

hydraulic unit cannot be disassembled.

• Do not drop or shock the hydraulic unit.
• Do not turn the hydraulic unit upside down or lay down 

the unit because the inner air becomes difficult to be 
bled.

INSTALLATION SERVICE POINT

.

>>A<< BRAKE TUBE CONNECTION

Install the brake pipe to the hydraulic unit as shown in the fig-
ure.

1. From master cylinder (primary) <Marking color: Blue>
2. To front brake (RH) 

<Marking color: Orange>

3. To front brake (LH)

<Marking color: Red>

WHEEL SPEED SENSOR

REMOVAL AND INSTALLATION

M1355005300612

<FRONT WHEEL SPEED SENSOR>

Refer to GROUP 35B, Wheel Speed Sensor 

P.35B-189

.

<REAR WHEEL SPEED SENSOR: FWD>

Refer to GROUP 35B, Wheel Speed Sensor 

P.35B-189

.

<REAR WHEEL SPEED SENSOR: AWD>

CAUTION

The vehicle speed detection encoder collects any 
metallic particle easily, because it is magnetized. 
Make sure that the encoder should not collect 
any metallic particle. Check that there is not any 
trouble prior to reassembling it.

<Vehicles with 7 seating capacity>

Refer to GROUP 35B, Wheel Speed Sensor
