2 CHECK SYMPTOM
1. Apply brake.
2. Start engine.
Does the symptom appear only when engine is started?
Ye s©Carry out self-diagnosis. Refer to BR-56, BR-58.
No©GO TO 3.
3 RECHECK SYMPTOM
Does the symptom appear when electrical equipment switches (such as headlamp) are operated?
Ye s©GO TO 4.
No©Go to“3. CHECK WARNING LAMP INDICATION”in“2. Unexpected Pedal Action”,
BR-82.
4 CHECK WHEEL SENSOR
Check wheel sensor shield ground. For location of shield ground, refer to wiring diagram and“HARNESS LAYOUT”in EL
section.
Is wheel sensor shield grounded properly?
Ye s©Check ABS actuator and electric unit pin terminals for damage or the connection of ABS
actuator and electric unit harness connector. Reconnect ABS actuator and electric unit
harness connector. Then retest.
No©Repair.
NOTE:
ABS may operate and cause vibration under any of the following
conditions.
+Applying brake gradually when shifting or operating clutch.
+Low friction (slippery) road.
+High speed cornering.
+Driving over bumps and pot holes.
+Engine speed is over 5,000 rpm with vehicle stopped.

Removal and InstallationNLBT0004+When removing or installing hood, place a cloth or other padding on hood. This prevents vehicle body from
being scratched.
+Bumper fascia is made of plastic. Do not use excessive force and be sure to keep oil away from it.
+Hood adjustment: Adjust at hinge portion.
+Hood lock adjustment: After adjusting, check hood lock control operation. Apply a coat of grease to hood
locks engaging mechanism.
+Hood opener: Do not attempt to bend cable forcibly. Doing so increases effort required to unlock hood.

Idle Air Volume LearningNLEC0562DESCRIPTIONNLEC0562S01ªIdle 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:
+Each time IACV-AAC valve, throttle body or ECM is replaced.
+Idle speed or ignition timing is out of specification.
PRE-CONDITIONINGNLEC0562S02Before 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.
+Battery voltage: More than 12.9V (At idle)
+Engine coolant temperature: 70 - 99ÉC (158 - 210ÉF)
+PNP switch: ON
+Electric 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.
+Cooling fan motor: Not operating
+Steering wheel: Neutral (Straight-ahead position)
+Vehicle speed: Stopped
+Transmission: Warmed-up
M/T models, drive vehicle for 10 minutes.
OPERATION PROCEDURENLEC0562S03With CONSULT-IINLEC0562S03011. Start engine and warm it up to normal operating temperature.
2. Check that all items listed under the topic ªPRE-CONDITION-
INGº (previously mentioned) are in good order.
3. Turn ignition switch ªOFFº and wait at least 9 seconds.
4. Start the engine and let it idle for at least 28 seconds.
5. Select ªIDLE AIR VOL LEARNº in ªWORK SUPPORTº mode.
6. Touch ªSTARTº and wait 20 seconds.
7. Make sure that ªCMPLTº is displayed on CONSULT-II screen.
If ªINCMPº is displayed, ªIdle Air Volume Learningº will not be
carried out successfully. In this case, find the cause of the
problem by referring to the NOTE below.
8. Rev up the engine two or three times. Make sure that idle
speed and ignition timing are within specifications.
