3.CHECK TARGET IDLE SPEED
1. Run engine at about 2,000 rpm for about 2 minutes under no load.
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-801, "Inspection".

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 function. (ECM may be the
cause of an incident, but
this is a rare case.)
2. Perform initialization and registration of all NATS ignition key IDs. Refer
to SEC-50, "BCM : Special Repair
Requirement" (With intelligent key system), SEC-190, "BCM : Work Procedure"
(Without intelligent key
system).
>> GO TO 4.
10.CHECK IGNITION TIMING
1. Run engine at idle.
2. Check ignition timing with a timing light.
For procedure, refer to EC-802, "Inspection".
For specification, refer to EC-807, "Ignition Timing".
- Timing indicator (1) Is the inspection result normal? YES >> GO TO 19.
NO >> GO TO 11.
11.PERFORM ACCELERATOR PEDAL RELEASED POSITION LEARNING
1. Stop engine.
2. Perform EC-542, "Work Procedure".
>> GO TO 12.
12.PERFORM THROTTLE VALVE CLOSED POSITION LEARNING
Perform EC-543, "Work Procedure".
>> GO TO 13.
13.PERFORM IDLE AIR VOLUME LEARNING
Perform EC-544, "Work Procedure".
Is idle air volume learning carried out successfully? YES >> GO TO 14.
NO >> Follow the instruction of IDLE AIR VOLUME LEARNING. Then GO TO 4.
14.CHECK TARGET IDLE SPEED AGAIN
1. Start engine and warm it up to normal operating temperature.
2. Check idle speed.
For procedure, refer to EC-801, "Inspection".
For specification, refer to EC-807, "Idle Speed".
Is the inspection result normal? YES >> GO TO 15.
NO >> GO TO 17.
15.CHECK IGNITION TIMING AGAIN
1. Run engine at idle.
2. Check ignition timing with a timing light.
For procedure, refer to EC-802, "Inspection".
For specification, refer to EC-807, "Ignition Timing".
- Timing indicator (1)
Is the inspection result normal? YES >> GO TO 19.
NO >> GO TO 16.
16.CHECK TIMING CHAIN INSTALLATION
Check timing chain installation. Refer to EM-181, "Exploded View".
Is the inspection result normal? YES >> GO TO 17.
NO >> Repair the timing chain installation. Then GO TO 4.
17.DETECT MALFUNCTIONING PART
