WORK ITEM CONDITION USAGE
IDLE AIR VOL LEARN The idle air volume that keeps the engine within the specified range is memorized in ecm. When learning the idle air volume
EVAP SYSTEM CLOSE Close the EVAP canister vent control valve in order to make
EVAP system close under the following conditions.
• Ignition switch ON
• Engine not running
• Ambient temperature is above 0 °C (32 °F).
• No vacuum and no high pressure in EVAP system
• Fuel tank temperature is more than 0 °C (32 °F).
• Within 10 minutes after starting “EVAP SYSTEM CLOSE”
• When trying to execute “EVAP SYSTEM CLOSE” under
the condition except above, CONSULT will discontinue it
and display appropriate instruction.
NOTE:
When starting engine, CONSULT may display “BAT-
TERY VOLTAGE IS LOW. CHARGE BATTERY”, even in
using charged battery. When detecting EVAP vapor leak-
age in the EVAP system
FUEL PRESSURE RELEASE Fuel pu mp will stop by touching “START” during idling.
crank a few times after engine stalls. When releasing fuel pressure from
fuel line
SELF-LEARNING CONT The coefficient of self-learning control mixture ratio returns to the original coefficient. When clearing mixture ratio self-
learning value
TARGET IGN TIM ADJ* Idle condition When adjusting target ignition tim- ing
TARGET IDLE RPM ADJ* Idle condition When setting target idle speed
VIN REGISTRATION In this mode, VIN is registered in ECM When registering VIN in ECM
CLSD THL POS LEARN Ignition on and engine stopped. When learning the throttle valve
closed position
SAVING DATA FOR REPLC CPU In this mode, save data that is in ECM. When ECM replaced.
WRITING DATA FOR REPLC CPU In this mode, write data stored by “SAVING DATA FOR RE-
PLC CPU” in work support mode to ECM. When ECM replaced.
TEST ITEM CONDITION JUDGMENT CHECK ITEM (REMEDY)
FUEL INJEC-
TION • Engine: Return to the original
non-standard condition
• Change the amount of fuel injec- tion using CONSULT. If malfunctioning symptom disap-
pears, see CHECK ITEM. • Harness and connectors

VALUES ON THE DIAGNOSIS TOOL
NOTE:
• The following table includes information (items) inapplicable to this vehicle. For information (items) applica- ble to this vehicle, refer to CONSULT display items.
• Numerical values in the following table are reference values.
• These values are input/output values that ECM receiv es/transmits and may differ from actual operations.
Example: The ignition timing shown by the timing light may differ from the ignition timing displayed on the
data monitor.
This occurs because the timing light shows a value calculated by ECM according to signals received from
the camshaft position sensor and other sensors related to ignition timing.
• For outlines of following items, refer to EC-601, "CONSULT Function"
.

*1: Accelerator pedal position sensor 2 signal and throttle
position sensor 2 signal are converted by ECM inter-
nally. Thus, they differ from ECM terminals voltage signal.
*2: Before measuring the terminal voltage, confir m that the battery is fully charged. Refer to PG-4, "How to
Handle Battery".
*3: The item is indicated, but not used.
