With GST
CONSULT-II or GST (Generic Scan Tool): Examples: P0117, P0335, P1260, etc.
These numbers are prescribed by ISO 15031-6.
(CONSULT-II also displays the malfunctioning parts and systems.)
A sample of CONSULT-II display for DTC and 1st/2nd trip DTC is
shown in the figure. DTC and 1st/2nd trip DTC are displayed in the
“SELF-DIAG RESULTS” mode of CONSULT-II.
“TIME” data shows how many times the vehicle was driven after the
last detection of DTC or 1st/2nd trip DTC. When DTC or 1st/2nd trip
DTC has been detected currently, “TIME” becomes “0”.
● CONSULT-II displays for DTC and 1st/2nd trip DTC become the
same.
● The output of a DTC indicates a malfunction. However, GST
does not indicate whether the malfunction is still occurring or
has occurred in the past and has returned to normal. CONSULT-
II can identify the malfunction status. Therefore the use of CON-
SULT-II (If available) is recommended.
FREEZE FRAME DATA
ECM records driving conditions such as calculated load value, engine coolant temperature, engine speed,
vehicle speed, and intake manifold pressure at the moment a malfunction is detected.
The data stored together with DTC is called Freeze Frame Data, and is displayed on CONSULT-II or GST.
When 1st/2nd trip DTC is detected, Freeze Frame Data is not recorded.
Only a set of Freeze Frame Data can be stored in the ECM memory. When ECM records Freeze Frame Data,
and another Freeze Frame Data is generated after that, the first (original) Freeze Frame Data is not updated in
ECM and it remains.
When the DTC is erased from ECM memory, Freeze Frame Data is erased with DTC. The procedure for eras-
ing DTC is described in EC-895, "
How to Erase DTC" .
HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION
How to Erase DTC
With CONSULT-II
The emission related diagnostic information in the ECM can be erased by selecting “ERASE” in the “SELF-
DIAG RESULTS” mode with CONSULT-II.
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 5
seconds and then turn it ON (engine stopped) again.
2. Touch “ENGINE”.
3. Touch “SELF-DIAG RESULTS”.
4. Touch “ERASE”. (The DTC in the ECM will be erased.)
