Operation Procedure
With CONSULT-II
NOTE:
Before perform Idle Air Volume Learning, make sure that Accelerator Pedal Released Position Learning and Throttle Valve Closed Position Learning are completed.
If not, perform ACCELERATOR PEDAL RELEASED POSITION LEARNING and THROTTLE VALVE CLOSED POSITION LEARNING .
- Start engine and warm it up to normal operating temperature.
- Check that all items listed under the topic PREPARATION (previously mentioned) are in good order.
- Select IDLE AIR VOL LEARN in WORK SUPPORT mode.
- Touch START and wait 20 seconds.
- Make sure that CMPLT is displayed on CONSULT-II screen. If CMPLT is not displayed, Idle Air Volume Learning will not be carried out successfully. In this case, find the cause of the incident by referring to the Diagnostic Procedure in Fig 4 .
- Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.
Without CONSULT-II
NOTE:
- It is better to count the time accurately with a clock.
- It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit has a malfunction.
NOTE:
Before perform Idle Air Volume Learning, make sure that Accelerator Pedal Released Position Learning and Throttle Valve Closed Position Learning are completed.
If not, perform ACCELERATOR PEDAL RELEASED POSITION LEARNING and THROTTLE VALVE CLOSED POSITION LEARNING .
- Start engine and warm it up to normal operating temperature.
- Check that all items listed under the topic PREPARATION (previously mentioned) are in good order.
- Turn ignition switch OFF and wait at least 10 seconds.
- Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
- Repeat the following procedure quickly five times within 5 seconds.
- Fully depress the accelerator pedal.
- Fully release the accelerator pedal.
- Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops blinking and turns ON.
- Fully release the accelerator pedal within 3 seconds after the MIL turns ON.
- Start engine and let it idle.
- Wait 20 seconds.
- Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.
- If idle speed and ignition timing are not within the specification, Idle Air Volume Learning will not be carried out successfully. In this case, find the cause of the incident by referring to the Diagnostic Procedure below.
