IDLE SPEED : Description
This describes how to check the idle speed. For the actual procedure, follow the instructions in "BASIC INSPECTION".
IDLE SPEED : Special Repair Requirement
1.CHECK IDLE SPEED
With CONSULT
Check idle speed in "DATA MONITOR" mode with CONSULT.
With GST
Check idle speed with Service $01 of GST.
IGNITION TIMING
IGNITION TIMING : Description
This describes how to check the ignition timing. For the actual procedure, follow the instructions in "BASIC INSPECTION".
IGNITION TIMING : Special Repair Requirement
1.CHECK IGNITION TIMING
1. Attach timing light to loop wires as shown.
VIN REGISTRATION
VIN REGISTRATION : Description
VIN Registration is an operation to register VIN in ECM. It must be performed each time ECM is replaced.
NOTE: Accurate VIN which is registered in ECM may be required for Inspection & Maintenance (I/M).
VIN REGISTRATION : Special Repair Requirement
1.CHECK VIN
Check the VIN of the vehicle and note it.
2.PERFORM VIN REGISTRATION
With CONSULT
ACCELERATOR PEDAL RELEASED POSITION LEARNING
ACCELERATOR PEDAL RELEASED POSITION LEARNING : Description
Accelerator Pedal Released Position Learning is an operation 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.
ACCELERATOR PEDAL RELEASED POSITION LEARNING : Special Repair Requirement
1.START
THROTTLE VALVE CLOSED POSITION LEARNING
THROTTLE VALVE CLOSED POSITION LEARNING : Description
Throttle Valve Closed Position Learning is an operation to learn the fully closed position of the throttle valve by monitoring the throttle position sensor output signal. It must be performed each time harness connector of electric throttle control actuator or ECM is disconnected or electric throttle control actuator is cleaned.
THROTTLE VALVE CLOSED POSITION LEARNING : Special Repair Requirement
1.START
WITH CONSULT
Check that throttle valve moves during the above 10 seconds by confirming the operating sound.
WITHOUT CONSULT
Check that throttle valve moves during the above 10 seconds by confirming the operating sound.
IDLE AIR VOLUME LEARNING
IDLE AIR VOLUME LEARNING : Description
Idle Air Volume Learning is a function of ECM to learn the idle air volume that keeps engine idle speed within the specific range. It must be performed under the following conditions:
IDLE AIR VOLUME LEARNING : Special Repair Requirement
1.PRECONDITIONING
Before performing Idle Air Volume Learning, check that all of the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are missed for even a moment.
2.PERFORM IDLE AIR VOLUME LEARNING
With CONSULT
3.PERFORM IDLE AIR VOLUME LEARNING
Without CONSULT
NOTE:
4.CHECK IDLE SPEED AND IGNITION TIMING
Rev up the engine two or three times and check that idle speed and ignition timing are within the specifications
5.DETECT MALFUNCTIONING PART-I
Check the following
6.DETECT MALFUNCTIONING PART-II
When the above three items check out OK, engine component parts and their installation condition are questionable.
Check and eliminate the cause of the incident.
It is useful to perform "TROUBLE DIAGNOSIS - SPECIFICATION VALUE". Refer to EC-149, "Description".
If any of the following conditions occur after the engine has started, eliminate the cause of the incident and perform Idle Air Volume Learning again:
EXHAUST VALVE TIMING CONTROL LEARNING
EXHAUST VALVE TIMING CONTROL LEARNING : Description
Exhaust Valve Timing Control Learning is a function of ECM to learn the characteristic of exhaust valve timing control magnet retarder by comparing the target angle of exhaust camshaft with the actual retarded angle of exhaust camshaft. It must be performed each time exhaust valve timing control magnet retarder is disconnected or replaced, or ECM is replaced.
