DIAGNOSIS SYSTEM (ECM)
*: Leaving cooling fan OFF with CONSULT while engine is running may cause the engine to overheat.
DTC & SRT CONFIRMATION MODE
SRT STATUS Mode
• For items whose SRT codes are set, “CMPLT” is displayed on the CONSULT screen; for items whose SRT
codes are not set, “INCMP” is displayed.
• “SRT STATUS” provides the presence or absence of permanent DTCs stored in ECM memory.
PERMANENT DTC STATUS Mode
How to display permanent DTC status
1.
Turn ignition switch OFF and wait at least 10 seconds.
2.
Turn ignition switch ON.
3.
Turn ignition switch OFF and wait at least 10 seconds.
4.
Turn ignition switch ON.
5.
Select “PERMANENT DTC STATUS” in “DTC & SRT CONFIRMATION” mode with CONSULT.
NOTE:
Permanent DTCs stored in ECM memory are displayed on the CONSULT screen to show if a driving pat-
tern required for erasing permanent DTCs is complete (CMPLT) or incomplete (INCMP).
CAUTION:
Since the “PERMANENT DTC STATUS” screen displays the previous trip information, repeat the
following twice to update the information: “Ignition switch OFF”, “Wait for more than 10 seconds”
and “Ignition switch ON”.
NOTE:
This mode is not used in regions that permanent DTCs are not regulated by law.
SRT WORK SUPPORT Mode
This mode enables a technician to drive a vehicle to set the SRT while monitoring the SRT status.
PERMANENT DTC WORK SUPPORT Mode
This mode enables a technician to drive a vehicle to complete the driving pattern that is required for erasing
permanent DTC.
NOTE:
ALTERNATOR DUTY
• Ignition switch: ON
• Change duty ratio using CON-
SULT.
Battery voltage changes.
• Harness and connectors
• Alternator
• IPDM E/R
POWER BALANCE
• Engine: After warming up, idle
the engine.
• A/C switch OFF
• Shift lever: P or N (CVT), Neutral
(M/T)
• Cut off each fuel injector signal
one at a time using CONSULT.
Engine runs rough or dies.
• Harness and connectors
• Compression
• Fuel injector
• Power transistor
• Spark plug
• Ignition coil

VALUES ON THE DIAGNOSIS TOOL
Remarks:
z
Specification data are reference values.
z
Specification data are output/input values which are detected or supplied by the ECM at the connector.
* Specification data may not be directly related to their components signals/values/operations.
I.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the specification data in spite of the
ignition timing not being adjusted to the specification data. this IGN TIMING monitors the data calculated by the ECM according to the signals
input from the camshaft position sensor and other ignition timing related sensors.

*1: Accelerator pedal position sensor 2 signal and throttle position sensor 2 signal are converted by ECM internally. Thus, they differ
from ECM terminals voltage signal.
*2: Before measuring the terminal voltage, confirm that the battery is fully charged. Refer to

NOTE:
• ECM is located in the engine room left side near battery.
• Connect a break-out box (EG17550000) and harness adapter (EG17550400) between the ECM and ECM
harness connector.
- Use extreme care not to 2 pins at one time.
- Data is for comparison and may not be exact.
• Specification data are reference values and are measured between each terminal and ground.
• Pulse signal is measured by CONSULT.
