DIAGNOSIS SYSTEM (ECM)
MAS A/F SE-B1
VThe signal voltage of the mass air flow sensor is dis-
played. • When the engine is stopped, a certain
value is indicated.
• When engine is running, specification range is indica ted in “SPEC”.
B/FUEL SCHDL ms“Base fuel schedule” indicates the fuel injection
pulse width programmed into ECM, prior to any
learned on board correction. When engine is running, specification
range is indicated in “SPEC”.
A/F ALPHA-B1 %The mean value of the air-fuel ratio feedback cor-
rection factor per cycle is indicated. • When the engine is stopped, a certain
value is indicated.
• When engine is running, specification
range is indica ted in “SPEC”.
• This data also includes the data for the air-fuel ratio learning control.
COOLAN TEMP/S °C or °F The engine coolant temperature (determined by the
signal voltage of the engine coolant temperature
sensor) is displayed. When the engine coolant temperature
sensor is open or short-circuited, ECM
enters fail-safe mode. The engine cool-
ant temperature determined by the ECM
is displayed.
A/F SEN1 (B1) VThe A/F signal computed from the input signal of
the air fuel ratio (A/F) sensor 1 is displayed.
HO2S2 (B1) VThe signal voltage of the heated oxygen sensor 2 is
displayed.
HO2S2 MNTR(B1) RICH/LEAN • Display of heated oxygen sensor 2 signal.
- RICH: means the amount of oxygen after three
way catalyst is relatively small.
- LEAN: means the amount of oxygen after three
way catalyst is relatively large. When the engine is stopped, a certain
value is indicated.
VHCL SPEED SE km/h or mph The vehicle speed computed from the vehicle
speed signal sent from combination meter is dis-
played.
BATTERY VOLT V The power supply voltage of ECM is displayed.
ACCEL SEN 1 VThe accelerator pedal position sensor signal volt-
age is displayed. ACCEL SEN 2 signal is converted by
ECM internally. Thus, it differs from
ECM terminal voltage signal.
ACCEL SEN 2
TP SEN 1-B1
VThe throttle position sensor signal voltage is dis-
played. TP SEN 2-B1 signal is converted by
ECM internally. Thus, it differs from
ECM terminal voltage signal.
TP SEN 2-B1
FUEL T/TMP SE
°C or °F The fuel temperature (determined by the signal volt-
age of the fuel tank temperature sensor) is dis-
played.
EVAP SYS PRES VThe signal voltage of EVAP control system pres-
sure sensor is displayed.
FUEL LEVEL SE VThe signal voltage of the fuel level sensor is dis-
played.
START SIGNAL ON/OFF Indicates start signal status [ON/OFF] computed by
the ECM according to the signals of engine speed
and battery voltage. After starting the engine, [OFF] is dis-
played regardless of the starter signal.
CLSD THL POS ON/OFF Indicates idle position [ON/OFF] computed by ECM
according to the accelerator pedal position sensor
signal.
AIR COND SIG ON/OFF Indicates [ON/OFF] condition of the air conditioner
switch as determined by the air conditioner signal.
PW/ST SIGNAL ON/OFF [ON/OFF] condition of the power steering system
(determined by the signal sent from EPS control
unit) is indicated.

NOTE:
If DTC P0340 is displayed with DTC P0643, first pe
rform the trouble diagnosis for DTC P0643. Refer to
EC-356, "
DTC Logic".
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5 V with igni-
tion switch ON.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE-I
1. Start engine and let it idle for at least 5 seconds. If engine does not start, crank engine for at least 2 seconds.
2. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Go to EC-282, "Diagnosis Procedure".
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE-II
1. Keep engine speed at more than 800 rpm for at least 5 seconds.
2. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Go to EC-282, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000012431485
1.CHECK STARTING SYSTEM
Turn ignition switch to START position.
Does the engine turn over? Does the starter motor operate?
YES >> GO TO 2.
NO >> Check starting system.
2.CHECK GROUND CONNECTION
1. Turn ignition switch OFF.
DTC No. Trouble diagnosis content DTC detecting condition Possible cause
