(f) Repeat the above procedure to bleed the air out of the
brake line for each wheel.
4. BLEED BRAKE ACTUATOR ASSY (W/ VSC)
NOTICE:
After performing the usual air bleeding in the brake system,
if the height or feel of the brake pedal cannot be obtained,
perform air bleeding in the brake actuator assy with a
hand-held tester by following procedures below.
(a) Depress the brake pedal more than 20 times with the en-
gine off.
(b) Connect the hand-held tester to the DLC3, then turn the
ignition switch to the ON position.
NOTICE:
Do not start the engine.
(c) Select ºAIR BLEEDINGº on the hand-held tester.
HINT:
Please refer to the Hand-Held Tester Operator's Manual for fur-
ther details.
(d) Bleed the air out of the regular brake line in ºStep1: In-
creaseº on the hand-held tester display.
NOTICE:
Perform the air bleeding by following the steps dis-
played on the hand-held tester.
Make sure that the brake fluid in the master cylinder
reservoir tank does not become empty.
(1) Connect the vinyl tube to either one of the bleeder
plugs.
(2) Depress the brake pedal several times, then loosen
the bleeder plug of one of the above wheels with the
pedal depressed.
(3) When fluid stops coming out, tighten the bleeder
plug, then release the brake pedal.
(4) Repeat (2) and (3) until all air in the fluid is complete-
ly bled out.
(5) Tighten the bleeder plug certainly.
Torque: 8.3 NVm (85 kgfVcm, 73 in.Vlbf)
(6) Repeat the above procedure to bleed the air out of
the brake line for each wheel.
(e) Bleed the air out of the suction line in ºStep2: Inhalationº
on the hand-held tester display.
NOTICE:
Perform the air bleeding by following the steps dis-
played on the hand-held tester.
Make sure that the brake fluid in the master cylinder
reservoir tank does not become empty.

(1) Connect the vinyl tube to the bleeder plug at the
right front wheel or the right rear wheel and loosen
the bleeder plug.
(2) Operate the brake actuator assy using the hand-
held tester to bleed the air.
NOTICE:
The operation stops automatically in 4 seconds.
At this time, be sure to release the brake pedal.
(3) Check that the operation has stopped, by referring
to the hand-held tester display.
(4) Repeat (2) and (3) until all the air in the fluid is com-
pletely bled out.
(5) Tighten the bleeder plug certainly.
Torque: 8.3 NVm (85 kgfVcm, 73 in.Vlbf)
(6) For the rest of the wheels, bleed the air in the same
way as stated in the above procedure.
(f) Bleed the air out of the pressure reduction line in ºStep3:
Decreaseº on the hand-held tester display.
NOTICE:
Perform air bleeding by following the steps displayed
on the hand-held tester.
Make sure that the brake fluid in the master cylinder
reservoir tank does not become empty.
(1) Connect a vinyl tube to either one of the bleeder
plugs.
(2) Loosen the bleeder plug.
(3) Using the hand-held tester, operate the brake ac-
tuator assy using hand-held tester, completely de-
press the brake pedal and keep it.
NOTICE:
The operation stops automatically in 4 seconds.
When performing this procedure continuously, an in-
terval of at least 20 seconds is required.
When the operation is completed, the brake pedal
slightly goes down. This is a normal phenomenon
caused when the solenoid opens.
During this procedure, the pedal seems heavy, but
completely depress it so that the brake fluid comes
out from the bleeder plug.
Be sure to keep depressing the brake pedal. Never
depress and release the pedal repeatedly.
(4) Tighten the bleeder plug, then release the brake
pedal.
(5) Repeat (2) to (4) until all the air in the fluid is com-
pletely bled out.
(6) Tighten the bleeder plug certainly.
Torque: 8.3 NVm (85 kgfVcm, 73 in.Vlbf)
(7) Repeat the above procedure to bleed the air out of
the brake line for each wheel.

(g) Bleed the air out of the regular brake line again in ºStep4:
Increaseº on the hand-held tester display.
NOTICE:
Perform air bleeding by following the steps displayed
on the hand-held tester.
Make sure that the brake fluid in the master cylinder
reservoir tank does not become empty.
(1) Connect the vinyl tube to either one of the bleeder
plug.
(2) Depress the brake pedal several times, then loosen
the bleeder plug of one of the above wheels with the
pedal depressed.
(3) When fluid stops coming out, tighten the bleeder
plug, then release the brake pedal.
(4) Repeat (2) and (3) until all the air in the fluid is com-
pletely bled out.
(5) Tighten the bleeder plug certainty.
Torque: 8.3 NVm (85 kgfVcm, 73 in.Vlbf)
(6) Repeat the above procedure to bleed the air out of
the brake line for each wheel.
5. CHECK FLUID LEVEL IN RESERVOIR
(a) Check the fluid level and add fluid if necessary.
Fluid: SAE J1703 or FMVSS No. 116 DOT3

ON-VEHICLE INSPECTION
1. INSPECT AIR FUEL RATIO COMPENSATION SYSTEM
(a) Inspect the voltage.
(1) Turn the ignition switch ON.
(2) Using a voltmeter, measure the voltage between
the terminals of the ECM.
Standard:
Tester ConnectionSpecified Condition
A1A+ (E9-22) - E1 (E8-1)3.3 V
A1A- (E9-30) - E1 (E8-1)3.0 V
A2A+ (E9-23) - E1 (E8-1)3.3 V
A2A- (E9-31) - E1 (E8-1)3.0 V
CAUTION:
Connect the test leads from the back side of the ECM con-
nector to the terminals.
HINT:
The voltage between the terminals of the ECM is constant re-
gardless of the voltage output from the air fuel ratio sensor (A/F
sensor).
(b) Check the operation.
(1) Connect the hand-held tester to the DLC3.
(2) Enter ºDIAGNOSIS/ENHANCED OBD II/DATA
LISTº, then select ºAFS B1 S1º and ºAFS B2 S1º to
display the monitor.
(3) Warm up the A/F sensor with the engine speed at
2,500 rpm for approximately 2 minutes.
(4) Keep the engine speed at 2,500 rpm, then confirm
that the waveform of ºAFS B1 S1º and ºAFS B2 S1º
are similar as shown in the illustration.
HINT:
The waveform in the illustration is a sample.
Only the hand-held tester displays the waveform of the
A/F sensor.
(c) Confirm that the display of ºDATA LISTº - ºO2S B1 S2º
and ºO2S B2 S2º fluctuates up and down between 0 V
and 1 V with the engine speed at 2,500 rpm.
