ON BOARD DIAGNOSTIC (OBD) SYSTEM
The DTC and 1st trip DTC are displayed at the same time. If the MI does not illuminate in diagnostic test mode
I (Malfunction warning), all displayed items are 1st trip DTCs. If only one code is displayed when the MI illumi-
nates in diagnostic test mode II (SELF-DIAGNOSTIC RESULTS), it is a DTC; if two or more codes are dis-
played, they may be either DTCs or 1st trip DTCs. DTC No. is same as that of 1st trip DTC. These unidentified
codes can be identified by using the CONSULT-II. A DTC will be used as an example for how to read a code.
A particular trouble code can be identified by the number of four-digit numeral flashes. The “zero” is indicated
by the number of ten flashes. The length of time the 1,000th-digit numeral flashes on and off is 1.2 seconds
consisting of an ON (0.6-second) - OFF (0.6-second) cycle.
The 100th-digit numeral and lower digit numerals consist of a 0.3-second ON and 0.3-second OFF cycle.
A change from one digit numeral to another occurs at an interval of 1.0-second OFF. In other words, the later
numeral appears on the display 1.3 seconds after the former numeral has disappeared.
A change from one trouble code to another occurs at an interval of 1.8-second OFF.
In this way, all the detected malfunctions are classified by their DTC numbers. The DTC “0000” refers to no
malfunction. (SeeEC-379, "
INDEX FOR DTC")
How to Erase Diagnostic Test Mode II (Self-diagnostic Results)
The DTC can be erased from the back up memory in the ECM by depressing accelerator pedal. Refer toEC-
405, "HOW TO SWITCH DIAGNOSTIC TEST MODE".
lIf the battery is disconnected, the DTC will be lost from the backup memory after approx 24 hours.
lBe careful not to erase the stored memory before starting trouble diagnoses.
DIAGNOSTIC TEST MODE II — HEATED OXYGEN SENSOR 1 MONITOR
In this mode, the MI displays the condition of the fuel mixture (lean or rich) which is monitored by the heated
oxygen sensor 1.
*: Maintains conditions just before switching to open loop.
To check the heated oxygen sensor 1 function, start engine in the Diagnostic Test Mode II and warm it up until
engine coolant temperature indicator points to the middle of the gauge.
Next run engine at about 2,000 rpm for about 2 minutes under no-load conditions. Then make sure that the MI
comes ON more than 5 times within 10 seconds with engine running at 2,000 rpm under no-load.

REAL TIME DIAGNOSIS IN DATA MONITOR MODE (RECORDING VEHICLE DATA)
Description
CONSULT-II has two kinds of triggers and they can be selected by
touching “SETTING” in “DATA MONITOR” mode.
1. “AUTO TRIG” (Automatic trigger):
–The malfunction will be identified on the CONSULT-II screen in
real time.
In other words, DTC/1st trip DTC and malfunction item will be
displayed if the malfunction is detected by ECM.
At the moment a malfunction is detected by ECM, “MONITOR”
in “DATA MONITOR” screen is changed to “Recording Data ...
xx%” as shown at right, and the data after the malfunction detec-
tion is recorded. Then when the percentage reached 100%,

“REAL-TIME DIAG” screen is displayed. If “STOP” is touched on the screen during “Recording Data ...

The recording time after the malfunction detection and the recording speed can be changed by “TRIG-
GER POINT” and “Recording Speed”. Refer to CONSULT-II OPERATION MANUAL.
2. “MANU TRIG” (Manual trigger):
–DTC/1st trip DTC and malfunction item will not be displayed automatically on CONSULT-II screen even
though a malfunction is detected by ECM.
DATA MONITOR can be performed continuously even though a malfunction is detected.
Operation
1. “AUTO TRIG”
–While trying to detect the DTC/1st trip DTC by performing the “DTC Confirmation Procedure”, be sure to
select to “DATA MONITOR (AUTO TRIG)” mode. You can confirm the malfunction at the moment it is
detected.
–While narrowing down the possible causes, CONSULT-II should be set in “DATA MONITOR (AUTO
TRIG)” mode, especially in case the incident is intermittent.
When you are inspecting the circuit by gently shaking (or twisting) the suspicious connectors, components
and harness in the “DTC Confirmation Procedure”, the moment a malfunction is found the DTC/1st trip
DTC will be displayed. (Refer to “Incident Simulation Tests” inGI-24, "
How to Perform Efficient Diagnosis
for an Electrical Incident".)
2. “MANU TRIG”
–If the malfunction is displayed as soon as “DATA MONITOR” is selected, reset CONSULT-II to “MANU
TRIG”. By selecting “MANU TRIG” you can monitor and store the data. The data can be utilized for further
diagnosis, such as a comparison with the value for the normal operating condition.

TROUBLE DIAGNOSIS
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.
lIf the real-time diagnosis results are NG and the on board diagnostic system results are OK when diagnosing the mass air flow sen-
sor, first check to see if the fuel pump control circuit is normal.

DTC P0117, P0118 ECT SENSOR
PFP:22630
Component DescriptionEBS00BGA
The engine coolant temperature sensor is used to detect the engine
coolant temperature. The sensor modifies a voltage signal from the
ECM. The modified signal returns to the ECM as the engine coolant
temperature input. The sensor uses a thermistor which is sensitive to
the change in temperature. The electrical resistance of the ther-
mistor decreases as temperature increases.

*: These data are reference values and are measured between ECM terminal 93
(Engine coolant temperature sensor) and body ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Component DescriptionEBS00BGZ
The heated oxygen sensor 1 is placed into the front tube. It detects
the amount of oxygen in the exhaust gas compared to the outside
air. The heated oxygen sensor 1 has a closed-end tube made of
ceramic zirconia. The zirconia generates voltage from approximately
1V in richer conditions to 0V in leaner conditions. The heated oxygen
sensor 1 signal is sent to the ECM. The ECM adjusts the injection
pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel
ratio occurs near the radical change from 1V to 0V.
