Removal and InstallationINFOID:0000000003811202
REMOVAL
Remove the vacuum hose and tube.
INSTALLATION
Note the following, install the vacuum hose and tube.
 Because vacuum hose contains a check valve, it must be installed in the correct position. Refer to the stamp
to confirm correct installation. Brake booster will not operate normally if the hose is installed in the wrong
direction.
 When installing vacuum hose, insert it until its tip reaches the
back-end of length (A) or further as shown in the figure.
- Face the marking side up when assembling of vacuum hose. (For
both side of vacuum hose of intake manifold side.)
- Face the marking side vehicle front when assembling of vacuum
hose. (For both side of vacuum hose of brake booster side)
CAUTION:
Never use lubricating oil during assembly.

VACUUM LINES
 Use a handy vacuum pump (A) to check.
 Replace vacuum hose assembly if vacuum hose and check valve
are malfunctioning.When connected to the brake booster side (B)
: Vacuum should decrease within 1.3 kPa (10 mmHg,
0.39 inHg, 0.013 bar) for 15 seconds under a vacuum
of −66.7 kPa (−500 mmHg, −19.70 inHg, −0.667 bar).
When connected to the engine side (C):
: Vacuum should not exist.

COMPONENT DIAGNOSIS
C1101, C1102, C1103, C1104 WHEEL SENSOR
DescriptionINFOID:0000000003766731
When the sensor rotor rotates, the magnetic field changes. Wheel sensor converts the magnetic field changes
to current signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).

DTC CONFIRMATION PROCEDURE
1.DTC REPRODUCTION PROCEDURE
1. Start the engine and drive the vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
2. Perform ABS actuator and electric unit (control unit) self-diagnosis.
Is DTC
“C1101”, “C1102”, “C1103” or “C1104” detected?
YES >> Proceed to diagnosis. Refer to BRC-16, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003766733
CAUTION:
Do not check between wheel sensor terminals.

YES >> GO TO 2.
NO >> Repair or replace damaged parts.
2.CHECK SENSOR AND SENSOR ROTOR
 Check sensor rotor for damage.
 Check wheel sensor for damage, disconnection or looseness.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair wheel sensor mount or replace sensor rotor. Then perform the self-diagnosis.
3.CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) connector.
3. Disconnect malfunctioning wheel sensor connector.
4. Check terminal to see if it is deformed, disconnected, looseness, etc.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace damaged parts.
