TROUBLE DIAGNOSIS - SPECIFICATION VALUE
Description
INFOID:0000000001693221
The specification (SP) value indicates the tolerance of the value that is displayed in “SPEC” of “DATA MONI-
TOR” mode of CONSULT-III during normal operation of the Engine Control System. When the value in “SPEC”
of “DATA MONITOR” mode is within the SP value, the Engine Control System is confirmed OK. When the
value in “SPEC” of “DATA MONITOR” mode is NOT within the SP value, the Engine Control System may have
one or more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not light the
MI.
The SP value will be displayed for the following three items:
• B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board correc-
tion)
• A/F ALPHA-B1 (The mean value of air-fuel ratio feedback correction factor per cycle)
• MAS A/F SE-B1 (The signal voltage of the mass air flow sensor)
Component Function Check

1.
START
Make sure that all of the following conditions are satisfied.
• Vehicle driven distance: More than 5,000 km (3,107 miles)
• Barometric pressure: 98.3 - 104.3 kPa (0.983 - 1.043 bar, 1.003 - 1.064 kg/cm
2
, 14.25 - 15.12 psi)
• Atmospheric temperature: 20 - 30
°
C (68 - 86
°
F)
• Engine coolant temperature: 75 - 95
°
C (167 - 203
°
F)
• Transmission: Warmed-up
- A/T models: After the engine is warmed up to normal operating temperature, drive vehicle until “FLUID
TEMP SE” fluid temperature sensor signal) indicates more than 60
°
C (140
°
F).
- M/T models: After the engine is warmed up to normal operating temperature, drive vehicle for 5 minutes.
• Electrical load: Not applied*
• Engine speed: Idle
*: Rear window defogger switch, air conditioner switch, lighting switch are OFF. Steering wheel is straight
ahead.

2.
PERFORM “SPEC” OF “DATA MONITOR” MODE
With CONSULT-III
NOTE:
Perform “SPEC” in “DATA MONITOR” mode in maximum scale display.
1.
EC-385, "BASIC INSPECTION : Special Repair Requirement"
.
2.
Select “B/FUEL SCHDL”, “A/F ALPHA-B1” and “MAS A/F SE-B1” in “SPEC” of “DATA MONITOR” mode
with CONSULT-III.
3.
Make sure that monitor items are within the SP value.
