TROUBLE DIAGNOSIS - SPECIFICATION VALUE
DescriptionINFOID:0000000001702599
The specification (SP) value indicates the tolerance of the value that is displayed in “DATA MONITOR (SPEC)”
mode of CONSULT-II during normal operation of the Engine Control System. When the value in “DATA MONI-
TOR (SPEC)” mode is within the SP value, the Engine Control System is confirmed OK. When the value in
“DATA MONITOR (SPEC)” 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
MIL.
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)
Testing ConditionINFOID:0000000001702600
• Vehicle driven distance: More than 5,000 km (3,107 miles)
• Barometric pressure: 98.3 - 104.3 kPa (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 and CVT models: After the engine is warmed up to normal operating temperature, drive vehicle until
“FLUID TEMP SE” (A/T or CVT) 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
- Rear window defogger switch, air conditioner switch, lighting switch are OFF. Steering wheel is straight
ahead.
• Engine speed: Idle
Inspection ProcedureINFOID:0000000001702601
NOTE:
Perform “DATA MONITOR (SPEC)” mode in maximum scale display.
1. Perform EC-69, "
Basic Inspection".
2. Confirm that the testing conditions indicated above are met.
3. Select “B/FUEL SCHDL”, “A/F ALPHA-B1” and “MAS A/F SE-
B1” in “DATA MONITOR (SPEC)” mode with CONSULT-II.
4. Make sure that monitor items are within the SP value.
5. If NG, go to EC-127, "
Diagnosis Procedure".

2. Attach probe circuit tester (in Volt range) to middle portion of
each filament.
3. If a filament is burned out, circuit tester registers 0 or battery
voltage.
4. To locate burned out point, move probe to left and right along fil-
ament. Test needle will swing abruptly when probe passes the
point.
Filament RepairINFOID:0000000001704180
REPAIR EQUIPMENT
• Conductive silver composition (DuPont No. 4817 or equivalent)
• Ruler 30 cm (11.8 in) long
• Drawing pen
• Heat gun
• Alcohol
• Cloth
REPAIRING PROCEDURE
1. Wipe broken heat wire and its surrounding area clean with a
cloth dampened in alcohol.
2. Apply a small amount of conductive silver composition to tip of
drawing pen.
