5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.
WorkINFOID:0000000003795060
 After removing and installing the opening/closing parts, be sure to carry out fitting adjustments to check their
operational.
 Check the lubrication level, damage, and wear of each part. If necessary, grease or replace it.

1.INSPECTION START
1. Check service records for any recent repairs that may indicate a related malfunction, or a current need for
scheduled maintenance.
2. Open engine hood and check the following:
- Harness connectors for improper connections
- Wiring harness for improper connections, pinches and cut
- Vacuum hoses for splits, kinks and improper connections
- Hoses and ducts for leaks
- Air cleaner clogging
- Gasket
3. Confirm that electrical or mechanical loads are not applied.
- Head lamp switch is OFF.
- Air conditioner switch is OFF.
- Rear window defogger switch is OFF.
- Steering wheel is in the straight-ahead position, etc.
4. Start engine and warm it up until engine coolant temperature
indicator points the middle of gauge.
Ensure engine stays below 1,000 rpm.
5. Run engine at about 2,000 rpm for about 2 minutes under no
load.
6. Check that no DTC is displayed with CONSULT-III or GST.
Are any DTCs detected?
YES >> GO TO 2.

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

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.
