ADDITIONAL SERVICE WHEN REPLACING ECM
Description
INFOID:0000000009178073
When replacing ECM, the following procedure must be performed. (For details, refer to
.)
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.
BEFORE REPLACEMENT
When replacing ECM, perform “SAVING DATA FOR REPLC CPU” in “WORK SUPPORT” of “ENGINE” by
using CONSULT to save current ECM data before replacement.
AFTER REPLACEMENT
After replacing ECM, the following items must be performed:
• Write data after replace CPU
• Accelerator pedal released position learning
• Throttle valve closed position learning
• Idle air volume learning
Work Procedure
INFOID:0000000009178074
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-466, "Removal and Installation"
for replacement of ECM.

ADDITIONAL SERVICE WHEN REPLACING 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.
5.
REPLACE ECM
Replace ECM. Refer to
EC-466, "Removal and Installation"
>> GO TO 6.
6.
PERFORM INITIALIZATION OF IVIS (NATS) SYSTEM AND REGISTRATION OF ALL IVIS (NATS) IGNI-
TION KEY IDS
Refer to
SEC-74, "ECM : Work Procedure"
.
>> GO TO 7.
7.
CHECK ECM DATA STATUS
Check if the data is successfully copied from the ECM at Step 1 (before replacement) and saved in CONSULT.
Is the data saved successfully?
YES
>> GO TO 8.
NO
>> GO TO 9.
8.
WRITE ECM DATA
With CONSULT
1. Select “WRITING DATA FOR REPLC CPU” in “WORK SUPPORT” mode of “ENGINE” using CONSULT.
2. Follow the instruction of CONSULT display.
NOTE:
The data saved by “SAVING DATA FOR REPLC CPU” is written to ECM.
>> GO TO 10.
9.
PERFORM VIN REGISTRATION
>> GO TO 10.
10.
PERFORM ACCELERATOR PEDAL RELEASED POSITION LEARNING
>> GO TO 11.
11.
PERFORM THROTTLE VALVE CLOSED POSITION LEARNING
>> GO TO 12.
12.
PERFORM IDLE AIR VOLUME LEARNING
>> END

ACCELERATOR PEDAL RELEASED POSITION LEARNING
Description
INFOID:0000000009178075
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 the harness connector of the accelerator pedal position sensor or ECM is disconnected.
Work Procedure
INFOID:0000000009178076
1.
START
1. Check 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.
