GENERAL PROCEDURES (BRAKE)

id041000800100

Wheel and Tire Installation

1. When installing the wheels and tires, tighten the

wheel nuts in a criss-cross pattern to the following
tightening torque.

Tightening torque

88.2— 117.6 N·m {9.00— 11.99 Kgf·m,

65.06— 86.73 ft·lbf}

Brake Lines Disconnection

1. If any brake line has been disconnected during the procedures, add brake fluid, bleed the brakes, and inspect

for leakage after the procedure has been completed.

Caution

• Brake fluid will damage painted surfaces. Be careful not to spill any on painted surfaces. If it is

spilled, wipe it off immediately.

Brake Pipe Flare Nut Tightening

1. Tighten the brake pipe flare nut using the SST (49 0259 770B) or any commercially available flare nut wrench.

Connector Disconnection

1. Disconnect the negative battery cable before performing any work that requires handling of connectors. (See

01-17-2 BATTERY REMOVAL/INSTALLATION[L3 WITH TC].)

DSC Related Parts

1. Make sure that there are no DTCs in the DSC memory after working on DSC related parts. If there are any

DTCs in the memory, clear them. (See 04-02-3 ON-BOARD DIAGNOSIS.)

DSC Related Part Sensor Initialization Procedure

Warning

• If the initialization procedure is not completed, the DSC will not operate properly and it might

cause an unexpected accident. Therefore, when replacing or removing the following parts, make
sure to perform the initialization procedure to insure proper DSC operation.

1. When replacing or removing the following parts, perform the initialization procedure. (See 04-15-17

COMBINED SENSOR INITIALIZATION PROCEDURE.)

• DSC HU/CM

• Combined sensor

GENERAL PROCEDURES

04-10–2

Steering Angle Sensor Initialization Procedure

Warning

• Unless the initialization procedure of the steering angle sensor is completed, the DSC will not

operate, causing an unexpected accident. Therefore, always perform the initialization procedure to
ensure DSC operation if the power supply to the BCM has been cut off due to disconnection of the
BCM connector or negative battery cable, or any other cause.

Caution

• The steering angle sensor initialization value of the BCM is stored using the battery power supply.

Therefore, the battery power supply of the BCM is cut and the stored steering angle initialization
value is cleared when any of the following items are performed.

— Negative battery cable disconnection

— BCM connector disconnection

— Steering angle sensor connector disconnection

— Fuse (ROOM) removal

— Wiring harness disconnection between battery, BCM connector, steering angle sensor

connector

• If the initialization procedure for the steering angle sensor has not been performed, when the

ignition switch is turned to the ON position, the DSC indicator light illuminates and the TCS OFF
light flashes to warn of a malfunction.

1. When replacing or removing the following parts, perform the initialization procedure. (See 09-40-8 STEERING

ANGLE SENSOR INITIALIZATION PROCEDURE.)

• Negative battery cable disconnection

• BCM connector disconnection

• Steering angle sensor connector disconnection

• Fuse (ROOM) removal

• Wiring harness disconnection between battery, BCM connector, steering angle sensor connector
