Accelerator Pedal Released Position Learning

ABS004AI

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 OFFand wait at least 10 seconds.

Throttle Valve Closed Position Learning

ABS004AJ

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.

Idle Air Volume Learning

ABS004AK

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.

Select “IDLE AIR VOL LEARN” in “WORK SUPPORT” mode.

6.

Touch “START” and wait 20 seconds.

7.

Make sure that “CMPLT” is displayed on CONSULT-II screen. If
“CMPLT” is not displayed, Idle Air Volume Learning will not be
carried out successfully. In this case, find the cause of the inci-
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.

  .

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.

Turn ignition switch OFF and wait at least 10 seconds.

6.

Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.

7.

Repeat the following procedure quickly five times within 5 seconds.

a.

Fully depress the accelerator pedal.

b.

Fully release the accelerator pedal.

8.

Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops
blinking and turned ON.

9.

Fully release the accelerator pedal within 3 seconds after the MIL turned ON.

10. Start engine and let it idle.

11. Wait 20 seconds.

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

specifications.

13. If idle speed and ignition timing are not within the specification, Idle Air Volume Learning will not be carried

out successfully. In this case, find the cause of the incident by referring to the DIAGNOSTIC PROCE-
DURE below.

DIAGNOSTIC PROCEDURE

If idle air volume learning cannot be performed successfully, proceed as follows:

1.

Check that throttle valve is fully closed.

2.

Check PCV valve operation.

3.

Check that downstream of throttle valve is free from air leakage.

4.

When the above three items check out OK, engine component parts and their installation condi-
tion are questionable. Check and eliminate the cause of the incident. 
It is useful to perform 

EC-126, "TROUBLE DIAGNOSIS - SPECIFICATION VALUE"

  .

5.

If any of the following conditions occur after the engine has started, eliminate the cause of the
incident and perform “Idle air volume learning” all over again:

●

Engine stalls.

●

Erroneous idle.

BASIC SERVICE PROCEDURE

Revision: 2004 November

2.

Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT”
mode with CONSULT-II.

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-II

1.

Remove fuel pump fuse located in IPDM E/R.

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 pressure from fuel line to eliminate danger.

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 Z50 models do not have fuel return system.
Use Fuel Pressure Gauge Kit (J-44321) to check fuel pressure.

1.

Release fuel pressure to zero. Refer to 

EC-45, "FUEL PRESSURE RELEASE"

  .

2.

Install the inline fuel quick disconnected fitting between fuel
damper and injector tube.

3.

Connect the fuel pressure test gauge (quick connector adapter
hose) to the inline fuel quick disconnected fitting.

4.

Turn ignition switch ON and check for fuel leakage.

5.

Start engine and check for fuel leakage.

6.

Read the indication of fuel pressure gauge.

7.

If result is unsatisfactory, go to next step.

8.

Check the following.

●

Fuel hoses and fuel tubes for clogging

●

Fuel filter for clogging

●

Fuel pump

●

Fuel pressure regulator for clogging

If OK, replace fuel pressure regulator.
If NG, repair or replace.
