DIAGNOSIS SYSTEM
1. DESCRIPTION for EURO −OBD (European spec.)
S When troubleshooting Euro −OBD vehicles, the only dif-
ference from the usual troubleshooting procedure is that
you c onnect an O BD scan t ool com plying wit h I SO
1 503 1− 4 or a hand −held tester to the vehicle, and read
the various data output from the vehicle’s ECM.
S Eur o −O BD r egulat ions r equir e t hat t he v ehicle’s on −
board computer illuminates the check engine warning
light (CHK ENG (MIL)) on the instrument panel when the
computer detects a malfunction in: 1) the emission control
system / components, or 2) the powertrain control compo-
nents (which affect vehicle emissions), or 3) the comput-
er. In addition, the applicable Diagnostic Trouble Codes
(DTCs) prescribed by ISO 1503 1− 4 are recorded in the
ECM memory (see page 05 −564).
If the malfunction does not reoccur in 3 consecutive trips, the
CHK ENG (MIL) goes off automatically but the DTCs remain re-
corded in the ECM memory.
S To check the DTCs, connect the OBD scan tool or hand −
held tester to Data Link Connector 3 (DLC3) on the ve-
hicle. The OBD scan tool or hand −held tester also en-
ables you to erase the DTCs and check the freeze frame
data and various forms of engine data. (See the instruc-
tion manual for the OBD scan tool or the hand −held tes-
ter).
S DTCs include ISO controlled codes and manufacturer
controlled codes. ISO controlled codes must be set ac-
cording to the ISO, while manufacturer controlled codes
can be set by a manufacturer within certain restrictions
(see the DTC chart on page 05 −564).
S The diagnosis system operates in normal mode during
normal vehicle use. In ”normal mode”, 2 trip detection log-
ic* is used to ensure accurate detection of malfunctions.
A ”check mode”, is also available to technicians as an op-
tion. In ”check mode”, 1 trip detection logic is used for sim-
ulating malfunction symptoms and increasing the sys-
tem’s ability to detect malfunctions, including intermittent
malfunctions (hand −held tester only)
(see page 05 −557).
S*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 ON again, and the
same malfunction is detected again, the CHK ENG (MIL)
will illuminate (2nd trip).

S Freeze frame data:
The freeze frame data records the engine conditions (fuel
system, calculated load, engine coolant temperature, fuel
trim, engine speed, vehicle speed, etc.) when a malfunc-
tion 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 malfunc-
tion occurred.
2. DESCRIPTION for M −OBD (Except European spec.)
S When troubleshoot Multiplex OBD (M −OBD) vehicles, the
only difference from the usual troubleshooting procedure
is that you connect the hand −held tester to the vehicle,
and read the various data output from the vehicle’s ECM.
S The vehicle’s on −board computer illuminates the check
engine warning lamp (CHK ENG (MIL)) on the instrument
panel when the computer detects a malfunction in the
computer itself or in drive system components. In addi-
tion, the applicable Diagnostic Trouble Codes (DTCs) are
recorded in the ECM memory (see page 05 −564).
If the malfunction does not recur, the CHK ENG (MIL) goes off
be disappeared by turning the ignition switch to OFF, but the re-
corded DTCs remain in the ECM memory.
S To check the DTCs, connect the hand −held tester to the
Data Link Connector 3 (DLC3) on the vehicle or connect
terminals TC and CG on the DLC3(DTCs will be displayd
on the multi −information display).
S The diagnosis system operates in normal mode during
normal vehicle use. In ”normal mode”, 2 trip detection log-
ic* is used to ensure accurate detection of malfunctions.
A ”check mode”, is also available to technicians as an op-
tion. In ”check mode”, 1 trip detection logic is used for sim-
ulating malfunction symptoms and increasing the sys-
tem’s ability to detect malfunctions, including intermittent
malfunctions (hand −held tester only)
(see page 05 −558).
S*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 ON again, and the
same malfunction is detected again, the CHK ENG (MIL)
will illuminate (2nd trip).

If the operation is not as specified, check the accelerator pedal
position sensor (see page 10 −22), wiring and ECM.
(d) Inspect the air assist system.
(1) Start the engine, then check that the check engine warning light does not light up.
(2) Allow the engine to warm up to the normal operating
temperature.
(3) Turn the A/C compressor ON to OFF, then check the
idle speed (see page 14 −87).
Idle speed (transmission in neutral): 800 á50 rpm
If the result is not as specified, check the wiring and ECM.
NOTICE:
Perform the inspection under condition without electrical
load.
(e) After taking the above steps (b) to (c), perform the driving test.
(f) Check that there is no sense of incongruity.

(a) Turn the ignition switch ON. Check that the charge warning light comes on.
(b) Start the engine, then check that the light goes off.
HINT:
If the light does not operate as specified, troubleshoot the charge warning light circuit.
7. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) If a tester is not available, connect a voltmeter to the
charging circuit as follows:
(1) Disconnect the wire from terminal B of the genera-
tor, then connect it to the negative (−) lead of the
ammeter.
(2) Connect the positive (+) lead of the ammeter to ter-
minal B of the generator.
(3) Connect the positive (+) lead of the voltmeter to ter-
minal B of the generator.
(4) Ground the negative (−) lead of the voltmeter.
(b) Check the charging circuit.
(1) Keep the engine speed at 2,000 rpm, then check
the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 12.9 to 14.9 V
8. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn the high beam headlights ON and turn the heater blower
switch to the ”HI” position.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
SIf the ammeter reading is less than the standard amperage, repair the generator.
SIf the battery is fully charged, the indication will sometimes be less than the standard amperage.
