DIAGNOSIS SYSTEM
1. DESCRIPTION
(a) When troubleshooting OBD II vehicles, the only
difference from the usual troubleshooting procedure
is to connect an OBD II scan tool complying with
SAE J1987 or a intelligent tester to the vehicle, and
read off various data output from the vehicle's ECM.
(b) OBD II regulations require that the vehicle's on-
board computer illuminate the Malfunction Indicator
Lamp (MIL) on the instrument panel when the
computer detects a malfunction in the computer
itself or in the drive system components whic h affect
the vehicle emissions. In addition to illuminating the
MIL when a malfunction is detected, the applicable
DTCs prescribed by SAE J2012 are recorded in the
ECM memory (See page AX-35).
If the malfunction does not occur in 3 consecutive
trips, the MIL goes off but the DTCs remain in the
ECM memory.
(c) To check the DTCs, connect the OBD II scan tool or
intelligent tester to the DLC3 of the vehicle. The
OBD II scan tool or intelligent tester also enables
you to erase the DTCs and check freeze frame data
and various forms of engine data (For operating
instructions, see the instruction book).
(d) The DTCs include SAE controlled codes and
Manufacturer controlled codes. SAE controlled
codes must be set as prescribed by the SAE, while
Manufacturer controlled codes can be set freely by
a manufacturer within the prescribed limits (See
page AX-35).
(e) The diagnosis system operates in "normal mode"
during the normal vehicle use. In normal mode, "2-
trip detection logic" is used to ensure accurate
detection of malfunction. "Check mode" is also
available to technicians as an option. In check
mode, "1-trip detection logic" is used for simulating
malfunction symptoms and increasing the system's
ability to detect malfunctions, including intermittent
malfunction.
(f) *2 trip detection logic: When a malfunction is first
detected, the malfunction is temporarily stored in
the ECM memory (1st trip). If the ignition switch is
turned off and then turned to the ON position again,
and same malfunction is detected again, the MIL will
illuminate.

(g) Freeze frame data records the engine conditions
(fuel system, calculated load, engine coolant
temperature, fuel trim, engine speed, vehicle speed,
etc.) when a malfunction is detected. When
troubleshooting, freeze frame data can help
determine if the vehicle was running or stopped, if
the engine was warmed up or not, if the air/fuel ratio
was Lean or Rich, and other data from the time the
malfunction occurred.
(h) The intelligent tester records freeze frame data in
five different instance: 1) 3 times before the DTC is
set, 2) once when the DTC is set, and 3) once after
the DTC is set. These data can be used to simulate
the vehicle's condition around the time when the
malfunction occurred. The data may help find the
cause of the malfunction, or judge if the DTC is
being caused by temporary malfunction or not.
2. INSPECT THE DLC3
(a) The vehicle's ECM uses ISO 15765-4 for
communication. The terminal arrangement of the
DLC3 complies with SAE J1962 and matches the
ISO 15765-4 format.
Terminals of DLC3
CAUTION:
*: Before measuring the resistance, leave the
vehicle as is for at least 1 minute and do not
operate the ignition switch, any other switches
or the doors.

HINT:
If your display shows UNABLE TO CONNECT TO
VEHICLE when you have connected the cable of
the OBD II scan tool or intelligent tester to the
DLC3, turned the ignition switch to the ON position
and operated the scan tool, there is a problem on
the vehicle side or tool side.
• If the communication is normal when the tool is
connected to another vehicle, inspect the DLC3
on the original vehicle.
• If the communication is still impossible when the
tool is connected to another vehicle, the problem
is probably in the tool itself, so consult the
Service Department listed in the tool's instruction
manual.
3. CHECK BATTERY VOLTAGE
(a) Measure the battery voltage.
Battery voltage:
11 to 14 V
If voltage is below 11 V, replace the battery before
proceeding.
4. CHECK MIL
(a) The MIL comes on when the ignition switch is
turned to the ON position and the engine is not
running.
HINT:
If the MIL does not light up, troubleshoot the
combination meter.
(b) When the engine is started, the MIL should go off. If
the lamp remains on, it means that the diagnosis
system has detected a malfunction or abnormality in
the system.
