Idle Speed and Ignition Timing Check
EBS00QUW
IDLE SPEED
With CONSULT-II
Check idle speed in “DATA MONITOR” mode with CONSULT-II.
Without CONSULT-II
Check the idle speed by installing the pulse type tachometer clamp on the loop wire or on suitable high-tension
wire which is installed between No. 1 ignition coil and No. 1 spark plug.
NOTE:
For the method of installing the tachometer, refer to
.
IGNITION TIMING
Any of following two methods may be used.
Method A
1.
Slide the harness protector of ignition coil No. to clear the wires.
2.
Attach timing light to the wires as shown.
3.
Check ignition timing.
Method B
1.
Remove No. 1 ignition coil.

Connect No. 1 ignition coil and No. 1 spark plug with suitable
high-tension wire as shown, and attach timing light clamp to this
wire.
3.
Check ignition timing.
Accelerator Pedal Released Position Learning
EBS00QUX
DESCRIPTION
“Accelerator Pedal Released Position Learning” is an operation to learn the fully released position of the accel-
erator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time
harness connector of accelerator pedal position sensor or ECM is disconnected.
OPERATION PROCEDURE
1.
Make sure that accelerator pedal is fully released.
2.
Turn ignition switch “ON” and wait at least 2 seconds.
3.
Turn ignition switch “OFF” wait at least 10 seconds.
4.
Turn ignition switch “ON” and wait at least 2 seconds.
5.
Turn ignition switch “OFF” wait at least 10 seconds.
Throttle Valve Closed Position Learning
EBS00QUY
DESCRIPTION
“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.
OPERATION PROCEDURE
1.
Make sure that accelerator pedal is fully released.
2.
Turn ignition switch “ON”.
3.
Turn ignition switch “OFF” wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.
Idle Air Volume Learning
EBS00QUZ
DESCRIPTION
“Idle Air Volume Learning” is an operation to learn the idle air volume that keeps each engine within the spe-
cific range. It must be performed 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.

PREPARATION
Before performing “Idle Air Volume Learning”, 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 - 95
°
C (158 - 203
°
F)
●
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.
●
Steering wheel: Neutral (Straight-ahead position)
●
Vehicle speed: Stopped
●
Transmission: Warmed-up
For models with CONSULT-II, drive vehicle until “FLUID TEMP SE” in “DATA MONITOR” mode of “A/T”
system indicates less than 0.9V.
For models without CONSULT-II, drive vehicle for 10 minutes.
OPERATION PROCEDURE
With CONSULT-II
1.
Perform
EC-576, "Accelerator Pedal Released Position Learning"
.
2.
Perform
EC-576, "Throttle Valve Closed Position Learning"
.
3.
Start engine and warm it up to normal operating temperature.
4.
Check that all items listed under the topic “PREPARATION” (previously mentioned) are in good order.
5.
Select “IDLE AIR VOL LEARN” in “WORK SUPPORT” mode.
6.
Touch “START” and wait 20 seconds.
