Exhaust Valve Timing Control Learning is an operation to learn the characteristic of exhaust valve timing con-
trol magnet retarder by comparing the target angle of exhaust camshaft with the actual retarded angle of
exhaust camshaft. It must be performed each time exhaust valve timing control magnet retarder is discon-
nected or replaced, or ECM is replaced.

OPERATION PROCEDURE

 With CONSULT-II

1.

Start engine and warm it up to normal operation temperature.

2.

Set shift lever in neutral position and confirm that following electrical or mechanical loads are not applied.

–

Headlamp switch is OFF

–

Air conditioner switch is OFF

–

Rear defogger switch is OFF

–

Steering wheel is in the straight-ahead position, etc

3.

Keep the engine speed between 1,800 and 2,000 rpm.

4.

Select “EXH V/T CONTROL LEARN” in “WORK SUPPORT”
mode with CONSULT-II.

5.

Touch “START” and wait 20 seconds.

6.

Make sure that “CMPLT” is displayed on CONSULT-II screen.

 Without CONSULT-II

1.

Start engine and warm it up to normal operation temperature.

2.

Set shift lever in neutral position and confirm that following electrical or mechanical loads are not applied.

–

Headlamp switch is OFF

Accelerator Pedal Released Position Learning

NBS006SP

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 and wait at least 10 seconds.

4.

Turn ignition switch ON and wait at least 2 seconds.

5.

Turn ignition switch OFF and wait at least 10 seconds.

Throttle Valve Closed Position Learning

NBS006SQ

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 and wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.

Idle Air Volume Learning

NBS006SR

DESCRIPTION

Idle Air Volume Learning is an operation to learn the idle air volume that keeps each engine within the specific
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 - 100

°

C (158 - 212

°

F)

●

Park/neutral position (PNP) switch: ON

●

Electric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine
is started, the headlamp will not be illuminated.

●

dent by referring to the DIAGNOSTIC PROCEDURE below.

8.

Rev up the engine two or three times and make sure that idle
speed and ignition timing are within the specifications.

 Without CONSULT-II

NOTE:

●

It is better to count the time accurately with a clock.

●

It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit
has a malfunction.
