BASIC INSPECTION : Special Repair Requirement".
Do you have CONSULT-III?
YES >> GO TO 7.
NO >> GO TO 9.
7.PERFORM SPEC IN DATA MONITOR MODE
With CONSULT-III
Make sure that “MAS A/F SE-B1”, “B/FUEL SCHDL” and “A/F ALPHA-B1” are within the SP value using
“SPEC” of “DATA MONITOR” mode with CONSULT-III. Refer to EC-114, "
Component Function Check".
Are they within the SP value?
YES >> GO TO 9.
NO >> GO TO 8.
8.DETECT MALFUNCTIONING PART BY TROUBLE DIAGNOSIS - SPECIFICATION VALUE
Detect malfunctioning part according to EC-115, "
Diagnosis Procedure".
Is malfunctioning part detected?
YES >> GO TO 11.
NO >> GO TO 9.
9.DETECT MALFUNCTIONING SY STEM BY SYMPTOM TABLE
Detect malfunctioning system according to EC-488, "
Symptom Table" based on the confirmed symptom in
step 4, and determine the trouble diagnosis or der based on possible causes and symptom.
>> GO TO 10.
10.DETECT MALFUNCTIONING PART BY DIAGNOSIS PROCEDURE
Inspect according to Diagnosis Procedure of the system.
NOTE:
The Diagnosis Procedure in EC section described based on open circuit inspection. A short circuit inspection
is also required for the circuit check in the Diagnosis Procedure. For details, refer to “Circuit Inspection” in GI-
25, "How to Perform Efficient Diagnosis for an Electrical Incident".
Is malfunctioning part detected?
YES >> GO TO 11.
NO >> Monitor input data from related sensors or c heck the voltage of related ECM terminals using CON-
SULT-III. Refer to EC-464, "
Reference Value".
11 .REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnosis Procedure again after repair and replace-
ment.
3. Check DTC. If DTC is displayed, erase it.
>> GO TO 12.
12.FINAL CHECK
When DTC was detected in step 2, perform DTC CO NFIRMATION PROCEDURE or Component Function
Check again, and then make sure that the malfunction have been repaired securely.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and make sure
that the symptom is not detected.
Is DTC detected and does symptom remain?
YES-1 >> DTC is detected: GO TO 10.
YES-2 >> Symptom remains: GO TO 6.

2. Rev engine (2,000 to 3,000 rpm) two or three times under no
load, then run engine at idle speed for about 1 minute.
3. Check idle speed.
For procedure, refer to EC-24, "
IDLE SPEED : Special Repair
Requirement". For specification, refer to EC-503, "Idle Speed".
Is the inspection result normal?
YES >> GO TO 10.
NO >> GO TO 4.
4.PERFORM ACCELERATOR PEDAL RE LEASED POSITION LEARNING
1. Stop engine.
2. Perform EC-25, "
ACCELERATOR PEDAL RELEASED POSITION LEARNING : Special Repair Require-
ment".
>> GO TO 5.
5.PERFORM THROTTLE VALVE CL OSED POSITION LEARNING
Perform EC-25, "
THROTTLE VALVE CLOSED POSITION LEARNING : Special Repair Requirement".
>> GO TO 6.
6.PERFORM IDLE AIR VOLUME LEARNING
Perform EC-26, "
IDLE AIR VOLUME LEARNING : Special Repair Requirement".
Is Idle Air Volume Learning carried out successfully?
YES >> GO TO 7.
NO >> Follow the instruction of Idle Air Volume Learning. Then GO TO 4.
7.CHECK IDLE SPEED AGAIN
1. Start engine and warm it up to normal operating temperature.
2. Check idle speed. For procedure, refer to EC-24, "
IDLE SPEED : Special Repair Requirement".
For specification, refer to EC-503, "
Idle Speed".

DTC Logic".
• Check crankshaft position sensor (POS) and circuit. Refer to EC-267, "
DTC Logic".
Is the inspection result normal?
YES >> GO TO 9.
NO >> Repair or replace. Then GO TO 4.
9.CHECK ECM FUNCTION
1. Substitute another known-good ECM to check ECM f unction. (ECM may be the cause of an incident, but
this is rare.)
2. Perform initialization of NVIS (NATS) system and registration of all NVIS (NATS) ignition key IDs. Refer to BL-247, "
ECM Re-communicating Function".
>> GO TO 4.
