HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION
How to Erase DTC
With CONSULT-III
The emission related diagnostic information in the ECM can be erased by selecting “ALL Erase” in the
“Description” of “FINAL CHECK” mode with CONSULT-III.
With GST
The emission related diagnostic information in the ECM can be erased by selecting Service $04 with GST.
1.
If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10
seconds and then turn it ON (engine stopped) again.
2.

2.
TM-34, "OBD-II Diagnostic Trouble Code (DTC)"
. (The DTC in TCM will be erased.)
3.
Change the diagnostic test mode from Mode II to Mode I by depressing the accelerator pedal. Refer to
EC-65, "Malfunction Indicator Lamp (MIL)"
• If the battery is disconnected, the emission-related diagnostic information will be lost within 24
hours.
• The following data are cleared when the ECM memory is erased.
- Diagnostic trouble codes
- 1st trip diagnostic trouble codes
- Freeze frame data
- 1st trip freeze frame data
- System readiness test (SRT) codes
- Test values
Actual work procedures are explained using a DTC as an example. Be careful so that not only the DTC, but all
of the data listed above, are cleared from the ECM memory during work procedures.

Fuel Cut Control (at No Load and High Engine Speed)
INFOID:0000000004297665
INPUT/OUTPUT SIGNAL CHART
*: This signal is sent to the ECM through CAN communication line.
SYSTEM DESCRIPTION
If the engine speed is above 1,800 rpm under no load (for example, the shift position is neutral and engine
speed is over 1,800 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies
based on engine speed.
Fuel cut will be operated until the engine speed reaches 1,500 rpm, then fuel cut will be cancelled.
NOTE:
This function is different from deceleration control listed under
.
