ADDITIONAL SERVICE WHEN REPLACING ECM

Description

INFOID:0000000011277895

When replacing ECM, the following procedure must be performed. (For details, refer to 

EC-139, "Work Proce-

dure"

.)

PROGRAMMING OPERATION

NOTE:

After replacing with a blank ECM, programming is required to write ECM information. Be sure to follow the pro-

cedure to perform the programming.

Work Procedure

INFOID:0000000011277896

1.

SAVE ECM DATA

With CONSULT

1. Turn ignition switch OFF.

2. Reconnect all harness connectors disconnected.

3. Turn ignition switch ON.

4. Select “SAVING DATA FOR REPLC CPU” in “WORK SUPPORT” mode of “ENGINE” using CONSULT.

5. Follow the instruction of CONSULT display.

NOTE:

• Necessary data in ECM is copied and saved to CONSULT.

• Go to Step 2 regardless of with or without success in saving data.

>> GO TO 2.

2.

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 part number when ordering ECM or the one included in the label on the container box.
Is the ECM a blank ECM?

YES

>> GO TO 3.

NO

>> GO TO 5.

3.

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 4.

>> GO TO 4.

4.

PERFORM ECM PROGRAMMING

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

NOTE:

• Refer to 

EC-502, "Removal and Installation"

 for replacement of ECM.

• 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 6.
