Checking Brake Fluid Level
lCheck fluid level in reservoir tank. It should be between Max.
and Min. lines on reservoir tank.
lIf fluid level is extremely low, check brake system for leaks.
lIf brake warning lamp comes on and fluid level is above
ªMINº mark, check brake fluid level switch and parking brake
switch.
Checking Brake Line
CAUTION:
If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.
1. Check brake lines (tubes and hoses) for cracks, deterioration
or other damage. Replace any damaged parts.
2. Check for oil leakage by fully depressing brake pedal while
engine is running.
Changing Brake Fluid
CAUTION:
lRefill with new brake fluid ªDOT 4º.
lAlways keep fluid level higher than minimum line on
reservoir tank.
lNever reuse drained brake fluid.
lBe careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately.
1. Clean inside of reservoir tank, and refill with new brake fluid.
2. Connect a vinyl tube to each air bleeder valve.
3. Drain brake fluid from each air bleeder valve by depressing
brake pedal while keeping reservoir level higher than mini-
mum line by adding new brake fluid.
4. Repeat until new brake fluid comes out of each air bleeder
valve.
Use same procedure as in bleeding hydraulic system to refill
brake fluid. Refer to ªBleeding Brake Systemº, BR-8.
Brake Burnishing Procedure
Burnish the brake contact surfaces according to the following
procedure after refinishing or replacing rotors, after replacing
pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Only perform this procedure under safe road and traffic con-
ditions. Use extreme caution.
1. Drive the vehicle on a straight smooth road at 50 km/h (31
MPH).

CAUTION:
Do not use any sharp tools or cleaning agents which con-
tains mineral oil. Damage to the installation can occur.
10. Clean the cylinder body and guide grooves in the torque
member.
11. Check the dust cover and guide sleeves for damage.
12. Measure the amount of wear on the brake pad
Standard pad thickness:
11 mm (0.43 in)
Pad wear limit:
2.0 mm (0.079 in)
14. Press the piston fully back with a suitable tool.
CAUTION:
Carefully monitor brake fluid level to avoid brake fluid from
returning to the reservoir when pushing back the piston.
Installation
1. Install the brake pad with a three-pronged retaining spring
into the piston.
2. Place the second brake pad into the guide groove of the
torque member on the outer side of the brake disc.
3. Place the cylinder body with the installed brake pad over the
brake disc and the second brake pad.
4. Tighten the guide pins witha7-mmAllen key.
5. Press back the protective caps into the guides sleeve.

The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, air con-

OFF]. This system indirectly relates to diagnostic trouble code 28 (Overheat).
Operation
ON-BOARD DIAGNOSIS LOGIC
This diagnosis continuously monitors the engine coolant temperature.
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.

CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the MA
section (ªChanging Engine Coolantº, ªENGINE MAINTENANCEº). Also, replace the engine oil.
a. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure
to use coolant with the proper mixture ratio. Refer to MA section (ªAnti-freeze Coolant Mixture
Ratioº, ªRECOMMENDED FLUIDS AND LUBRICANTSº).
b. After refilling coolant, run engine to ensure that no water-flow noise is emitted.

This system automatically controls engine idle speed to a specified
level. Idle speed is controlled through fine adjustment of the
amount of air which by-passes the throttle valve via IACV-AAC
valve. The IACV-AAC valve changes the opening of the air by-pass
passage to control the amount of auxiliary air. This valve is actu-
ated by a step motor built into the valve, which moves the valve in
the axial direction in steps corresponding to the ECM output sig-
nals. One step of IACV-AAC valve movement causes the respec-
tive opening of the air by-pass passage. (i.e. when the step
advances, the opening is enlarged.) The opening of the valve is
varied to allow for optimum control of the engine idling speed. The
crankshaft position sensor (POS) detects the actual engine speed
and sends a signal to the ECM. The ECM then controls the step
position of the IACV-AAC valve so that engine speed coincides with
the target value memorized in ECM. The target engine speed is the
lowest speed at which the engine can operate steadily. The opti-
mum value stored in the ECM is determined by taking into consid-
eration various engine conditions, such as during warm up,
deceleration, and engine load (air conditioner, power steering, cool-
ing fan operation and electrical load).
COMPONENT DESCRIPTIONNCEC0279S02The IACV-AAC valve is operated by a step motor for centralized
control of auxiliary air supply. This motor has four winding phases
and is actuated by the output signals of ECM which turns ON and
OFF two windings each in sequence. Each time the IACV-AAC
valve opens or closes to change the auxiliary air quantity, the ECM
sends a pulse signal to the step motor. When no change in the
auxiliary air quantity is needed, the ECM does not issue the pulse
signal. A certain voltage signal is issued so that the valve remains
at that particular opening.
