IDLE AIR VOLUME LEARNING
DescriptionINFOID:0000000009462557
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 the electric throttle c ontrol actuator or ECM is replaced.
• Idle speed or ignition timing is out of the specification.
Work ProcedureINFOID:0000000009462558
1.PRECONDITIONING
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 position: P or N
• Electric load switch: OFF
(Air conditioner, head lamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine is
started the head lamp will not illuminate.
• Steering wheel: Neutral (Straight-ahead position)
• Vehicle speed: Stopped
• Transmission: Warmed-up
- With CONSULT: Drive vehicle until “ATF TEMP SEN” in “DATA MONITOR” mode of “CVT” system indicates
less than 0.9 V.
- Without CONSULT: Drive vehicle for 10 minutes.

4. Turn ignition switch OFF and wait at least 10 seconds.
5. Confirm that accelerator pedal is fully releas ed, turn ignition switch ON and wait 3 seconds.
6. Repeat the following procedure quickly 5 times within 5 seconds.
- Fully depress the accelerator pedal.
- Fully release the accelerator pedal.
7. Wait 7 seconds, fully depress the accelerator pedal for approx. 20 seconds until the MIL stops blinking
and turns ON.

9. Start engine and let it idle.
10. Wait 20 seconds.
>> GO TO 4.
4.CHECK IDLE SPEED AND IGNITION TIMING
Rev up the engine 2 or 3 times and check that idle s peed and ignition timing are within the specifications.
For procedure, refer to EC-992, "Work Procedure"
and EC-993, "Work Procedure".
For specifications, refer to EC-998, "Idle Speed"
and EC-998, "Ignition Timing".
Is the inspection result normal?
YES >> INSPECTION END
NO >> GO TO 5.
5.DETECT MALFUNCTIONING PART-I
Check the following
• Check that throttle valve is fully closed.
• Check PCV valve operation.
• Check that downstream of throttle valve is free from air leakage.
Is the inspection result normal?
YES >> GO TO 6.
NO >> Repair or replace malfunctioning part.
6.DETECT MALFUNCTIONING PART-II
Engine component parts and their installation condition are questionable. Check and eliminate the cause of
the incident.
It is useful to perform “TROUBLE DIAGNOSIS - SPECIFICATION VALUE”. Refer to EC-701, "Description"
.
If any of the following conditions occur after the engi ne has started, eliminate the cause of the incident and
perform Idle Air Volume Learning again:
• Engine stalls.
• Incorrect idle.

FUEL PRESSURE CHECK
CAUTION:
• The fuel hose connection method used when taki ng fuel pressure check must not be used for other
purposes.
• Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
• Be careful not to scratch or get the fuel hose conn ection area dirty when servicing, so that the quick
connector o-ring ma intains seal ability.
• Use Fuel Pressure Gauge Kit [SST: — (J-44321)] an d Fuel Pressure Adapter [SST: — (J-44321-6)] to
check fuel pressure.
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because th is models do not have fuel return system.
1.FUEL PRESSURE CHECK
1. Release fuel pressure to zero.
2. Remove fuel hose using Quick Connector Release [SST: — (J-45488)]. CAUTION:
• Do not twist or kink fuel hose because it is plastic hose.
• Do not remove fuel hose from quick connector.
• Keep fuel hose connections clean.
3. Install Fuel Pressure Adapter [SST: — (J-44321-6)] (B) and Fuel Pressure Gauge kit [SST: — (J44321)] (A) as shown in figure.
CAUTION:
• Do not distort or bend fuel rail tube when installing fuel
pressure gauge adapter.
• When reconnecting fuel hose, check the original fuel hose
(1) for damage and abnormality.
4. Turn ignition switch ON (reactivate fuel pump) and check for fuel leakage.
5. Start engine and check for fuel leakage.
6. Read the indication of fuel pressure gauge kit [SST: — (J- 44321)].
CAUTION:
• During fuel pressure check, check for fuel leakage from fuel connection every 3 minutes.
Is the inspection result normal?

OUTLINE
In order to set all SRTs, the self-diagnoses as in
the “SRT ITEM” table must have been performed at least
once. Each diagnosis may require actual driving for a long period of time under various conditions.
SRT ITEM
The table below shows required self-diagnostic items to set the SRT to “CMPLT”.
*1: Though displayed on the CONSULT screen, “HO2S HTR” is not SRT item.
*2: If completion of several SRTs is required, perfo rm driving patterns (DTC confirmation procedure), one by
one based on the priority for models with CONSULT.
