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.

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 below.
Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.

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.
1. Fully depress the accelerator pedal.
2. 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 turned ON.
Start engine and let it idle.
Wait 20 seconds.
