ADDITIONAL SERVICE WHEN REPLACING ECM

Description

INFOID:0000000009022480

When replacing ECM, perform additional service.

NOTE:

After replacing with a blank ECM, programming is required to write ECM information. To perform the opera-

tion, always follow the work instructions. Refer to 

EC-111, "Work Procedure"

.

Work Procedure

INFOID:0000000009022481

1.

CHECK ECM PART NUMBER

Check ECM part number to see whether it is blank ECM or not.

NOTE:

• Part number of blank ECM is 23703 - 

×××××.

• Check the part number when ordering ECM or with delivered package label.
Is the ECM a blank ECM?

YES

>> GO TO 2.

NO

>> GO TO 4.

2.

SAVE ECM PART NUMBER

Read out the part number from the old ECM and save the number, following the programming instructions.

Refer to “CONSULT Operation Manual”.

NOTE:

• The ECM part number is saved in CONSULT.

• Even when ECM part number is not saved in CONSULT, go to 3.

>> GO TO 3.

3.

PERFORM ECM PROGRAMMING

After replacing ECM, perform the ECM programming. Refer to “CONSULT Operation Manual”.

NOTE:

• During programming, maintain the following conditions:

- Ignition switch: ON

- Electric load: OFF

- Brake pedal: Not depressed

- Battery voltage: 12 - 13.5 V (Be sure to check the value of battery voltage by selecting “BATTERY VOLT” in

“Data monitor” of CONSULT.)

>> GO TO 5.

4.

ACCELERATOR PEDAL RELEASED POSITION LEARNING

Description

INFOID:0000000009022482

Accelerator Pedal Released Position Learning is a function of ECM to learn the fully released position of the

accelerator 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.

Work Procedure

INFOID:0000000009022483

1.

START

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

THROTTLE VALVE CLOSED POSITION LEARNING

Description

INFOID:0000000009022484

Throttle Valve Closed Position Learning is a function of ECM 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 connec-

tor of electric throttle control actuator or ECM is disconnected or electric throttle control actuator inside is

cleaned.

Work Procedure

INFOID:0000000009022485

1.

START

With CONSULT

1. Turn ignition switch ON.

2. Select “CLSD THL POS LEARN” in “WORK SUPPORT” mode.

3. Follow the instructions on the CONSULT display.

4. Turn ignition switch OFF and wait at least 10 seconds.

Check that throttle valve moves during the above 10 seconds by confirming the operating sound.

Without CONSULT

1. Start the engine.

NOTE:

Engine coolant temperature is 25

°C (77°F) or less before engine starts.

2. Warm up the engine.

NOTE:

Raise engine coolant temperature until it reaches 65

°C (149°F) or more.

3. Turn ignition switch OFF and wait at least 10 seconds.

Check that throttle valve moves during the above 10 seconds by confirming the operating sound.
