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:
This mode is not used in regions that permanent DTCs are not regulated by law.

VALUES ON THE DIAGNOSIS TOOL
NOTE:
The following table includes information (items) inapplicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.
z
Numerical values in the following table are reference values.
z
These values are input/output values that ECM receives/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
cam shaft position sensor and other sensors related to ignition timing.
For outlines of following items, refer to

*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

PHYSICAL VALUES
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.
