“Fuel injection system status” at the moment a malfunction is detected is displayed.
One mode in the following is displayed.
Mode2: Open loop due to detected system malfunction
Mode3: Open loop due to driving conditions (power enrichment, deceleration enleanment)
Mode4: Closed loop - using oxygen sensor(s) as feedback for fuel control
Mode5: Open loop - has not yet satisfied condition to go to closed loop FUEL SYS-B2
CAL/LD VALUE [%]

COOLANT TEMP
[°C] or [°F]
The engine coolant temperature at the moment a malfunction is detected is displayed.
L-FUEL TRM-B1 [%]
“Long-term fuel trim” at the moment a malfunction is detected is displayed.
The long-term fuel trim indicates much more gradual feedback compensation to the base fuel schedule
than short-term fuel trim. L-FUEL TRM-B2 [%]
S-FUEL TRM-B1 [%]
“Short-term fuel trim” at the moment a malfunction is detected is displayed.
The short-term fuel trim indicates dynamic or instantaneous feedback compensation to the base fuel
schedule. S-FUEL TRM-B2 [%]

played.
When the engine is stopped, a certain value is
indicated.
When engine is running specification range is
indicated in “SPEC”. MAS A/F SE-B2 [V]
B/FUEL SCHDL [msec]
“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 correc-
tion factor per cycle is indicated.
When the engine is stopped, a certain value is
indicated.

ratio learning control.
When engine is running specification range is
indicated in “SPEC”. A/F ALPHA-B2 [%]
COOLAN TEMP/S [°C]
or [°F]
The engine coolant temperature (determined by the
signal voltage of the engine coolant temperature sen-
sor) is displayed.When the engine coolant temperature sensor
is open or short-circuited, ECM enters fail-safe
mode. The engine coolant temperature deter-
mined by the ECM is displayed.
A/F SEN1 (B1) [V]

HO2S2 (B1) [V]
The signal voltage of the heated oxygen sensor 2 is
displayed.
HO2S2 (B2) [V]
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.
HO2S2 MNTR(B2)
[RICH/LEAN]
VHCL SPEED SE [km/
h] or [mph]
The vehicle speed computed from the vehicle speed
signal sent from combination meter is displayed.
BATTERY VOLT [V]
The power supply voltage of ECM is displayed.
ACCEL SEN 1 [V]
The accelerator pedal position sensor signal voltage is
displayed.ACCEL SEN 2 signal is converted by ECM
internally. Thus, it differs from ECM terminal
voltage signal. ACCEL SEN 2 [V]
