CAUTION:
Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly
depressed (just place a foot on it). However, this is normal.
When shifting gears
When driving on slippery road
During cornering at high speed
When passing over bumps or grooves [at approximately 50 mm (1.97 in) or more]
When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher]
1.SYMPTOM CHECK 1
Check that there are pedal vibrations when the engine is started.
Do vibrations occur?
YES >> GO TO 2.
NO >> Inspect the brake pedal.
2.SYMPTOM CHECK 2
Check that there are ABS operation noises when the engine is started.
Do the operation noises occur?
YES >> GO TO 3.
NO >> Perform self-diagnosis.
3.SYMPTOM CHECK 3

INSPECTION AND ADJUSTMENT
THROTTLE VALVE CLOSED POSITION LEARNING
THROTTLE VALVE CLOSED POSITION LEARNING : DescriptionINFOID:0000000003856455
Throttle Valve Closed Position Learning is an operation to learn the fully closed position of the throttle valve by
monitoring the throttle position sensor output signal. It must be performed each time harness connector of
electric throttle control actuator or ECM is disconnected.
THROTTLE VALVE CLOSED POSITION LEARNING : Special Repair Requirement
INFOID:0000000003856456
1.START
1. Check that accelerator pedal is fully released.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
Check that throttle valve moves during above 10 seconds by confirming the operating sound.

IDLE AIR VOLUME LEARNING
IDLE AIR VOLUME LEARNING : DescriptionINFOID:0000000003856457
Idle Air Volume Learning is a function of ECM to learn the idle air volume that keeps engine idle speed within
the specific range. It must be performed under the following conditions:
Each time electric throttle control actuator or ECM is replaced.
Idle speed or ignition timing is out of specification.
IDLE AIR VOLUME LEARNING : Special Repair RequirementINFOID:0000000003856458
1.PRECONDITIONING
Before performing Idle Air Volume Learning, check 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 12.9 V (At idle)
Engine coolant temperature: 70 - 100°C (158 - 212°F)
Selector lever: P or N
Electric load switch: OFF
(Air conditioner, head lamp, rear window defogger)
-For vehicle equipped with daytime light systems, perform one of the following procedures before
starting engine not to illuminate headlamps.
Apply parking brake
Set lighting switch to the 1st position
Steering wheel: Neutral (Straight-ahead position)
Vehicle speed: Stopped
Transmission: Warmed-up
- With CONSULT-III: Drive vehicle until “ATF TEMP SEN” in “DATA MONITOR” mode of “CVT” system indi-
cates less than 0.9 V.
- Without CONSULT-III: Drive vehicle for 10 minutes.
Will CONSULT-III be used?
YES >> GO TO 2.
NO >> GO TO 3.
2.PERFORM IDLE AIR VOLUME LEARNING
With CONSULT-III
1. Perform EC-15, "
ACCELERATOR PEDAL RELEASED POSITION LEARNING : Special Repair Require-
ment".
2. Perform EC-16, "
THROTTLE VALVE CLOSED POSITION LEARNING : Special Repair Requirement".
3. Start engine and warm it up to normal operating temperature.
4. Select “IDLE AIR VOL LEARN” in “WORK SUPPORT” mode.
5. Touch “START” and wait 20 seconds.
