Does the ABS warning lamp activate?
No
EYe s
Carry out self-diagnosis.
Refer to BR-67.
Go toin Diagnostic Procedure 7,
BR-86.
Note: ABS does not work when vehicle speed is under 10
km/h (6 MPH).
Diagnostic Procedure 10 (Pedal vibration and
noise)
INSPECTION START
1. Apply brake.
2. Start engine.
3. Does the symptom appear only
when engine is started?
No
EYe s
Carry out self-diagnosis.
Refer to BR-67.
CHECK IF SYMPTOM APPEARS.
Does the symptom appear when elec-
trical equipment switches (such as
headlamp) are operated?
Ye s
ENo
Go toin Diagnostic
Procedure 7, BR-86.
CHECK WHEEL SENSOR.
Check wheel sensor shield ground. For
location of shield ground, refer to wiring
diagram and ªHARNESS LAYOUTº in
EL section.
OK
ENG
Repair wheel sensor.
CHECK HARNESS CONNECTOR.
Check ABS actuator and electric unit
pin terminals for damage or the con-
nection of ABS actuator and electric
unit harness connector.
Reconnect ABS actuator and electric
unit harness connector. Then retest.
Note: ABS may operate and cause vibration under any of
the following conditions.

TROUBLE DIAGNOSES FOR SYMPTOMS
BR-87

Basic Inspection
Precaution:
Perform Basic Inspection without electrical or mechanical
loads applied;
lHeadlamp switch is off,
lAir Conditioner switch is off,
lRear defogger switch is off,
lSteering wheel is in the straight-ahead position, etc.
BEFORE STARTING
1. Check service records for any
recent repairs that may indicate a
related problem, or the current need
for scheduled maintenance.
2. Open engine hood and check the
following:
lHarness connectors for faulty con-
nections
lVacuum hoses for splits, kinks, or
faulty connections
lWiring for faulty connections,
pinches, or cuts
3. Using priming pump, bleed air from
fuel system. Refer to ªFuel Filter
Checkº in MA section.
CONNECT CONSULT-II TO THE
VEHICLE.
Connect ªCONSULT-IIº to the data link
connector for CONSULT-II and select
ªENGINEº from the menu. Refer to EC-
CD-27.
DOES ENGINE START?
Ye s
ENo
Turn ignition switch to
the ªLOCKº position, wait
5 seconds and then start
engine. If engine fails to
start, check malfunction
item.
Run engine for 10 minutes.
CHECK IDLE SPEED.
Read engine idle speed in
ªDATA MONITORº mode with
CONSULT-II.
825 rpm   25 (in N position)
---------------------------------------------------------------------------------------------------------------------------------OR---------------------------------------------------------------------------------------------------------------------------------
Check idle speed using tachom-
eter tester.

Idle Air Volume LearningNCEC0541DESCRIPTIONNCEC0541S01ªIdle Air Volume Learningº is an operation to learn the idle air vol-
ume that keeps each engine within the specific range. It must be
performed under any of the following conditions:
IEach time IACV-AAC valve, throttle body or ECM is replaced.
IIdle speed or ignition timing is out of specification.
PRE-CONDITIONINGNCEC0541S04Before performing ªIdle Air Volume Learningº, make sure that all of
the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are
missed for even a moment.
IBattery voltage: More than 12.9V (At idle)
IEngine coolant temperature: 70 - 99ÉC (158 - 210ÉF)
IPNP switch: ON
IElectric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, set lighting
switch to the 1st position to light only small lamps.
ICooling fan motor: Not operating
ISteering wheel: Neutral (Straight-ahead position)
IVehicle speed: Stopped
ITransmission: warmed-up (Drive vehicle for 10 minutes.)
OPERATION PROCEDURENCEC0541S02With CONSULT-IINCEC0541S02011. Turn ignition switch ªONº and wait at least 1 second.
2. Turn ignition switch ªOFFº and wait at least 9 seconds.
3. Start the engine and warm it up to normal operating tempera-
ture.
4. Check that all items listed under the topic ªPRE-CONDITION-
INGº (previously mentioned) are in good order.
