Description
When replacing ECM, the following procedure must be performed. (For details, refer to EC-136, "Work Procedure".)
PROGRAMMING OPERATION
NOTE: After replacing with a blank ECM, programming is required to write ECM information. Be sure to follow the procedure to perform the programming.
Work Procedure
1.SAVE ECM DATA
With CONSULT
NOTE:
>> GO TO 2.
2.CHECK ECM PART NUMBER
Check ECM part number to see whether it is blank ECM or not.
NOTE:
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:
>> GO TO 4.
4.PERFORM ECM PROGRAMMING
After replacing ECM, perform the ECM programming. Refer to CONSULT Operation Manual.
NOTE:
>> GO TO 6.
5.REPLACE ECM
Replace ECM. Refer to EC-499, "Removal and Installation".
>> GO TO 6.
6.PERFORM INITIALIZATION OF IVIS (NATS) SYSTEM AND REGISTRATION OF ALL IVIS (NATS) IGNITION KEY IDS
Refer to SEC-62, "Work Flow" (with intelligent key system) or SEC-150, "Work Flow" (without intelligent key system).
>> 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
NOTE: The data saved by “SAVING DATA FOR REPLC CPU” is written to ECM.
>> GO TO 10.
9.PERFORM VIN REGISTRATION
Refer to EC-138, "Work Procedure".
>> GO TO 10.
10.PERFORM ACCELERATOR PEDAL RELEASED POSITION LEARNING
Perform Accelerator Pedal Released Position Learning. Refer to EC-139, "Work Procedure".
>> GO TO 11.
11.PERFORM THROTTLE VALVE CLOSED POSITION LEARNING
Perform Throttle Valve Closed Position Learning. Refer to EC-140, "Work Procedure".
>> GO TO 12.
12.PERFORM IDLE AIR VOLUME LEARNING
Perform Idle Air Volume Learning. Refer to EC-141, "Work Procedure".
>> END
