This function allows to read if ECM has completed
the self-diagnoses of major emission control systems and
components. For SRT, refer to EC-596, "DIAGNOSIS DESCRIPTION : System Readiness Test (SRT) Code"
.
Operation Procedure
1. Turn ignition switch ON and wait 20 seconds.
2. SRT status is indicated as shown blow. • ECM continues to illuminate MIL if all SRT codes are set.
• ECM blinks MIL for about 10 seconds if all SRT codes are not set.
MALFUNCTION WARNING MODE
Description
In this function ECM turns on or blinks MIL when it detects a malfunction in the emission control system com-
ponents and/or the powertrain control components (which affe ct vehicle emissions) to inform the driver that a
malfunction has been detected.
Operation Procedure
1. Turn ignition switch ON.
2. Check that MIL illuminates. If it remains OFF, check MIL circuit. Refer to EC-973, "Diagnosis Procedure"
.
3. Start engine and let it idle. • For two trip detection logic diagnoses, ECM turns on MIL when it detects the same malfunction twice in
the two consecutive driving cycles.
• For 1st trip detection logic diagnoses, ECM turns on MIL when it detects a malfunction in one driving
cycle.
• ECM blinks MIL when it detects a malfunction t hat may damage the three way catalyst (misfire).
SELF-DIAGNOSTIC RESULTS MODE
Description
This function allows to indicate DTCs or 1st trip DTCs stored in ECM according to the number of times MIL is
blinking.
How to Set Self-diagnostic Results Mode
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 mal- function.
• After ignition switch is turned off, ECM is a lways released from the “self-diagnostic results” mode.
1. Confirm that accelerator pedal is fully releas ed, turn ignition switch ON and wait 3 seconds.
2. Repeat the following procedure quick ly five times within 5 seconds.
• Fully depress the accelerator pedal.
• Fully release the accelerator pedal.

IDLE AIR VOLUME LEARNING
DescriptionINFOID:0000000009462557
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:
• Each time the electric throttle c ontrol actuator or ECM is replaced.
• Idle speed or ignition timing is out of the specification.
Work ProcedureINFOID:0000000009462558
1.PRECONDITIONING
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.
• Battery voltage: More than 12.9 V (At idle)
• Engine coolant temperature: 70 - 100 °C (158 - 212 °F)
• Selector lever position: P or N
• Electric load switch: OFF
(Air conditioner, head lamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine is
started the head lamp will not illuminate.
• Steering wheel: Neutral (Straight-ahead position)
• Vehicle speed: Stopped
• Transmission: Warmed-up
- With CONSULT: Drive vehicle until “ATF TEMP SEN” in “DATA MONITOR” mode of “CVT” system indicates
less than 0.9 V.
- Without CONSULT: Drive vehicle for 10 minutes.
Will CONSULT be used?
YES >> GO TO 2.
NO >> GO TO 3.
2.PERFORM IDLE AIR VOLUME LEARNING
With CONSULT
1. Perform Accelerator Pedal Released Position Learning. Refer to EC-681, "Work Procedure"
.
2. Perform Throttle Valve Closed Position Learning. Refer to EC-682, "Work Procedure"
.
3. Start engine and warm it up to normal operating temperature.
4. Select “IDLE AIR VOL LEA RN” in “WORK SUPPORT” mode.
5. Touch “START” and wait 20 seconds.
Is
“CMPLT” displayed on CONSULT screen?
YES >> GO TO 4.
NO >> GO TO 5.
3.PERFORM IDLE AIR VOLUME LEARNING
Without CONSULT
NOTE:
• It is better to count the time accurately with a clock.
• It is impossible to switch the di agnostic mode when an accelerator pedal position sensor circuit has
a malfunction.
1. Perform Accelerator Pedal Released Position Learning. Refer to EC-681, "Work Procedure"
.
2. Perform Throttle Valve Closed Position Learning. Refer to EC-682, "Work Procedure"
.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch OFF and wait at least 10 seconds.
5. Confirm that accelerator pedal is fully releas ed, turn ignition switch ON and wait 3 seconds.
6. Repeat the following procedure quickly 5 times within 5 seconds.
- Fully depress the accelerator pedal.
- Fully release the accelerator pedal.
7. Wait 7 seconds, fully depress the accelerator pedal for approx. 20 seconds until the MIL stops blinking
and turns ON.
8. Fully release the accelerator pedal within 3 seconds after the MIL turns ON.
