IDLE AIR VOLUME LEARNING
DescriptionINFOID:0000000009462138
Idle Air Volume Learning is a function of ECM to lear
n the idle air volume that keeps each engine idle speed
within the specific range. It must be per formed under any of the following conditions:
• Each time electric throttle control actuator or ECM is replaced.
• Idle speed or ignition timing is out of specification.
Work ProcedureINFOID:0000000009462139
1.PRECONDITIONING
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 12.9 V (At idle)
• Engine coolant temperature: 70 - 100 °C (158 - 212 °F)
• Selector lever : P or N
• Electric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime running light systems, set lighting switch to the 1st position to
light only small lamps.
• Steering wheel: Neutral (Straight-ahead position)
• Vehicle speed: Stopped
• Transmission: Warmed-up
- With CONSULT Drive vehicle until “ATF TENP SEN” in “DATA MONITO R” mode of “CVT” system indicates less than 0.9 V.
- Without CONSULT Drive vehicle for 10 minutes.
Do you have CONSULT?
YES >> GO TO 2.
NO >> GO TO 3.
2.IDLE AIR VOLUME LEARNING
With CONSULT
1. Perform Accelerator Pedal Released Position Learning. Refer to EC-177, "Work Procedure"
.
2. Perform Throttle Valve Closed Position Learning. Refer to EC-178, "Work Procedure"
.
3. Start engine and warm it up to normal operating temperature.
4. Select “IDLE AIR VOL LEARN” in “WORK SUPPORT” mode of “ENGINE”.
5. Touch “START” and wait 20 seconds.
Is
“CMPLT” displayed on CONSULT screen?
YES >> GO TO 4.
NO >> GO TO 5.
3.IDLE AIR VOLUME LEARNING
Without CONSULT
NOTE:
• It is better to count the time accurately with a clock.
• It is impossible to switch the di agnostic mode when an accelerator pedal position sensor circuit has
a malfunction.
1. Perform Accelerator Pedal Released Position Learning. Refer to EC-177, "Work Procedure"
.
2. Perform Throttle Valve Closed Position Learning. Refer to EC-178, "Work Procedure"
.
3. Start engine and warm it up to normal operating temperature.
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 quick ly five times within 5 seconds.
- Fully depress the accelerator pedal.
- Fully release the accelerator pedal.
7. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops
blinking and turned ON.

FUEL PRESSURE RELEASE
1.FUEL PRESSURE RELEASE
With CONSULT
1. Turn ignition switch ON.
2. Perform “FUEL PRESSURE RELEA SE” in “WORK SUPPORT” mode of “ENGINE” using CONSULT.
3. Start engine.
4. After engine stalls, crank it two or three times to release all fuel pressure.
5. Turn ignition switch OFF.
Without CONSULT
1. Remove fuel pump fuse located in IPDM E/R. For the fuse number, refer to EC-117, "Wiring Diagram"
. For
the fuse arrangement, refer to PG-72, "Fuse, Connector and Terminal Arrangement"
.
2. Start engine.
3. After engine stalls, crank it two or three times to release all fuel pressure.
4. Turn ignition switch OFF.
5. Reinstall fuel pump fuse after servicing fuel system.

FUEL PRESSURE CHECK
CAUTION:
Before disconnecting fuel line, release fuel pr essure from fuel line to eliminate danger.
NOTE:
• Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel
pressure cannot be completely released because th is models do not have fuel return system.
• Use Fuel Pressure Gauge Kit [SST: (J-44321)] to check fuel pressure.
1.FUEL PRESSURE CHECK
1. Release fuel pressure to zero.
2. Connect fuel tube adapter [SST:KV10120000] (B) to quick con-
nector.
3. Turn ignition switch ON and check for fuel leakage.
4. Start engine and check for fuel leakage.
5. Read the indication of fuel pressure gauge.
Is the inspection result normal?
YES >> INSPECTION END
NO >> GO TO 2.
2.CHECK FUEL HOSES AND FUEL TUBES
Check fuel hoses and fuel tubes for clogging.
Is the inspection result normal?
YES >> Replace “fuel filter and fuel pump assembly”. Refer to FL-6, "Removal and Installation".
NO >> Repair or replace error-detected parts.
A : Fuel pressure gauge
C : Fuel feed hose
: Vehicle front
At idling : Approximately 350 kPa (3.57 kg/cm2, 51 psi)
