ABS, EBD SYSTEM
If ABS malfunction electrically, ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp will turn on. If
EBD malfunction electrically, brake warning lamp, ABS warning lamp, VDC OFF indicator lamp and SLIP indi-
cator lamp will turn on. Simultaneously, the VDC/TCS/ABS become one of the following conditions of the fail-
safe function.

ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)
 For malfunction of ABS, only the EBD is activated and the condition of vehicle is the same condition of vehi-
cles without TCS/ABS system.
NOTE:
ABS self-diagnosis sound may be heard. That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.
 For malfunction of EBD, EBD and ABS become inoperative, and the condition of vehicle is the same as the
condition of vehicles without TCS/ABS, EBD system.
VDC/TCS
If VDC/TCS/ABS system malfunction electrically, VDC OFF indicator lamp, SLIP indicator lamp are turned on,
and the condition of vehicle is the same as the condition of vehicles without VDC/TCS control.
CAUTION:
If the Fail-Safe function is activated, then perform self-diagnosis for VDC/TCS/ABS control system.

 To remove brake tube, use a flare nut wrench to prevent flare nuts and brake tube from being dam-
aged. To install, use flare nut crowfoot and torque wrench.
 Do not apply excessive impact to ABS actuator and electric unit (control unit), such as dropping it.
 Do not remove and install actuator by holding harness.
 After work is completed, bleed air from brake tube. Refer to BR-10, "
Bleeding Brake System".
 After installing harness connector in the ABS actuator and electric unit (control unit), make sure
connector is securely locked.
 When replacing ABS actuator and electric unit (control unit), make sure to adjust neutral position of
steering angle sensor. Refer to BRC-66, "
ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL
POSITION : Description".
Install ABS actuator and electric unit (control unit) as per the follow-
ing steps.
1. Temporarily tighten mounting bolt (1) because the bracket (2) is
temporarily being hold.
2. Tighten mounting bolt (3) while holding the bracket.
3. Tighten mounting bolts to the specified torque in the order of (4),
(1).

RADIATOR
WARNING:
Never remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine
coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to
release built-up pressure. Carefully remove radiator cap by turning it all the way.
1. Remove the following parts:
 Engine under cover.
 Air duct (inlet): Refer to EM-26, "
Exploded View".
 Horn: Refer to HRN-6, "
Exploded View".
 Hood lock: Refer to DLK-220, "
Exploded View".
2. Drain engine coolant from radiator. Refer to CO-8, "
Draining".
CAUTION:
 Perform this step when the engine is cold.
 Never spill engine coolant on drive belt.
3. Disconnect reservoir tank hose from radiator pipe (upper).
4. Disconnect CVT fluid cooler hoses from radiator.
 Install blind plug to avoid leakage of CVT fluid.
5. Disconnect Low-pressure flexible hose from lower pressure pipe, and then move it to aside. Refer to HA-
38, "Exploded View".
6. Remove radiator cap adapter and radiator hoses (upper) and radiator pipe (upper) assembly.
CAUTION:
Be careful not to allow engine coolant to contact drive belt.
7. Disconnect radiator hose (lower) from radiator.
8. Remove condenser. Refer to HA-46, "
Exploded View".
CAUTION:
Be careful not to damage condenser core.
9. Remove radiator upper clip (2) by pulling the tabs (A) outside to
release the lock (B) and then remove mounting rubbers (upper)
(1).
CAUTION:
Never pull the tabs outside excessively to prevent it from
damping.
10. Lift up and remove radiator from front of radiator core support.
CAUTION:
Be careful not to damage or scratch on radiator core.
INSTALLATION
Note the following, and installation is the reverse order of removal.
Radiator Upper Clip
Install radiator upper clip on radiator core connection as follows:
1. Install mounting rubbers (upper) (1) on mounting pins (A) of radi-
ator.
2. Align radiator upper clip (2) with radiator core connection (B),
then insert radiator upper clip straight into radiator core connec-
tions until a click is heard.
3. After connecting radiator upper clip, use the following method to
check it is fully connected.
 Visually confirm that two radiator upper clips are connected to
radiator core connections.
 Move radiator upper clip and the radiator forward and backward to check they are securely connected.
