1.DIAGNOSIS SYSTEM
(a)Description for Euro±OBD

When troubleshooting Euro±OBD vehicles, the
only difference from the usual troubleshooting pro-
cedure is that you connect an OBD scan tool com-
plying with ISO 15031±4 or a hand±held tester to
the vehicle, and read the various data output from
the vehicle's ECM.

Euro±OBD regulations require that the vehicle's
on±board computer illuminates the check engine
warning light (CHK ENG) on the instrument panel
when the computer detects a malfunction in the
emission control system / components or in the
power train control components which affect vehicle
emissions, or a malfunction in the computer. In addi-
tion to an illumination of the CHK ENG when a mal-
function is detected, the applicable Diagnostic
Trouble Codes (DTCs) prescribed by ISO 15031±4
are recorded in the ECM memory (See page
05±544). If the malfunction does not reoccur in 3
consecutive trips, the CHK ENG goes off automati-
cally but the DTCs remain recorded in the ECM
memory.

To check the DTCs, connect the OBD scan tool or
hand±held tester to Data Link Connector 3 (DLC3)
on the vehicle. The OBD scan tool or hand±held
tester also enables you to erase the DTCs and
check the freeze frame data and various forms of
engine data. (For operating instructions, see the
OBD scan tool's instruction book.)

DTCs include ISO controlled codes and manufac-
turer controlled codes. ISO controlled codes must
be set as prescribed by the ISO, while manufacturer
controlled codes can be set freely by the manufac-
turer within the prescribed limits (See DTC chart on
page 05±544).

The diagnosis system operates in the normal mode
during normal vehicle use. It also has a check (test)
mode for technicians to simulate malfunction symp-
toms and troubleshoot. Most DTCs use 2 trip detec-
tion logic* to prevent erroneous detection, and to
ensure a thorough malfunction detection. By
switching the ECM to the check mode using hand±
held tester when troubleshooting, a technician can
cause the CHK ENG to illuminate for a malfunction
that is only detected once or momentarily (Hand±
held tester only) (See step 3).

* 2 trip detection logic
When a logic malfunction is first detected, the pend-
ing fault code is stored in the ECM memory (1st trip).
If the same malfunction is detected again during the
second drive test, this second detection causes the
CHK ENG to illuminate (2nd trip) (However, the igni-
tion switch must be turned OFF between the 1st trip
and 2nd trip).

Freeze frame data:
The freeze frame data records the engine condi-
tions (fuel system, calculator load, engine coolant
temperature, engine speed, vehicle speed, etc.)
when the malfunction is detected. When trouble-
shooting, it is useful for determining whether the ve-
hicle was running or stopped, the engine was
warmed up or not, etc. at the time of the malfunc-
tion.

Priorities for troubleshooting:
If troubleshooting priorities for multiple DTCs are
given in the applicable DTC chart, these should be
followed.
(b) Check the DLC3.
The vehicle's ECM uses the ISO 9141±2(Euro±OBD)
communication protocol. The terminal arrangement of
the DLC3 complies with ISO 15031±03 and matches the
ISO 9141±2 format.

HINT:
If the display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of the hand±held tester to
the DLC3, turned the ignition switch ON and operated the
hand±held tester, there is a problem on the vehicle side or tool
side.

If communication is normal when the tool is connected to
another vehicle, inspect the DLC3 on the original vehicle.

If communication is still impossible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Deparment listed in the
tool's instruction manual.
