*1: This item includes 1st trip DTCs.
*2: This mode includes 1st trip freeze frame data or freeze frame data. The items appear on CONSULT-II screen in freeze frame data
mode only if a 1st trip DTC or DTC is detected. For details, refer to EC-61, EC-71.

FUNCTIONNLEC0034S03
Diagnostic test mode Function
Work supportThis mode enables a technician to adjust some devices faster and more accurately by following the
indications on the CONSULT-II unit.
Self-diagnostic resultsSelf-diagnostic results such as 1st trip DTC, DTCs and 1st trip freeze frame data or freeze frame
data can be read and erased quickly.*1
Data monitor Input/Output data in the ECM can be read.
Data monitor (spec)Input/Output specifications of the basic fuel schedule, AFM, A/F feedback control value and the
other data monitor items can be read.
Active testDiagnostic Test Mode in which CONSULT-II drives some actuators apart from the ECMs and also
shifts some parameters in a specified range.
DTC and SRT confirmation The status of system monitoring tests and the self-diagnosis status/result can be confirmed.
ECM part number ECM part numbers can be read.
*1 The following emission-related diagnostic information is cleared when the ECM memory is erased.

DIAG TROUBLE
CODE
[PXXXX]+Engine Control component part/control system has a trouble code, it is displayed as ªPXXXXº. (Refer
to ªAlphabetical & P No. Index for DTCº, EC-16.)
FUEL SYS-B1+ªFuel injection system statusº at the moment a malfunction is detected is displayed.
+One mode in the following is displayed.
ªMODE 2º: Open loop due to detected system malfunction
ªMODE 3º: Open loop due to driving conditions (power enrichment, deceleration enrichment)
ªMODE 4º: Closed loop - using oxygen sensor(s) as feedback for fuel control
ªMODE 5º: Open loop - has not yet satisfied condition to go to closed loop
CAL/LD VALUE [%]+The calculated load value at the moment a malfunction is detected is displayed.
COOLANT TEMP [ÉC]
or [ÉF]+The engine coolant temperature at the moment a malfunction is detected is displayed.
L-FUEL TRIM-B1 [%]+ªLong-term fuel trimº at the moment a malfunction is detected is displayed.
+The long-term fuel trim indicates much more gradual feedback compensation to the base fuel sched-
ule than short-term fuel trim.

signalsMain
signalsDescription Remarks
ENG SPEED [rpm]jj+Indicates the engine speed computed from
the POS signal of the crankshaft position
sensor.+Accuracy becomes poor if engine
speed drops below the idle rpm.
+If the signal is interrupted while the
engine is running, an abnormal
value may be indicated.
MAS A/F SE-B1 [V]jj+The signal voltage of the mass air flow sen-
sor is displayed.+When the engine is stopped, a cer-
tain value is indicated.
B/FUEL SCHDL
[msec]+ªBase fuel scheduleº indicates the fuel injec-
tion pulse width programmed into ECM, prior
to any learned on board correction.
A/F ALPHA-B1 [%]j+Indicates the mean value of the air-fuel ratio
feedback correction factor per cycle.+When the engine is stopped, a cer-
tain value is indicated.
+This data also includes the data for
the air-fuel ratio learning control.
COOLAN TEMP/S
[ÉC] or [ÉF]jj+The engine coolant temperature (determined
by the signal voltage of the engine coolant
temperature sensor) is displayed.+When the engine coolant tempera-
ture sensor is open or short-
circuited, ECM enters fail-safe
mode. The engine coolant tempera-
ture determined by the ECM is dis-
played.
HO2S1 (B1) [V]jj+The signal voltage of the heated oxygen sen-
sor 1 (front) is displayed.
HO2S2 (B1) [V]j+The signal voltage of the heated oxygen sen-
sor 2 (rear) is displayed.
HO2S1 MNTR (B1)
[RICH/LEAN]j+Display of heated oxygen sensor 1 (front)
signal during air-fuel ratio feedback control:
RICH ... means the mixture became ªrichº,
and control is being affected toward a leaner
mixture.
LEAN ... means the mixture became ªleanº,
and control is being affected toward a rich
mixture.+After turning ON the ignition switch,
ªRICHº is displayed until air-fuel mix-
ture ratio feedback control begins.
+When the air-fuel ratio feedback is
clamped, the value just before the
clamping is displayed continuously.
