TROUBLE DIAGNOSIS - SPECIFICATION VALUE

TROUBLE DIAGNOSIS - SPECIFICATION VALUEPFP:00031
DescriptionBBS004YI
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
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 cor-
rection)

A/F ALPHA-B1/B2 (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 ConditionBBS004YJ

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/cm2 , 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” (A/T fluid temperature sensor signal) indicates more than 60°C (140°F).
–CVT models: After the engine is warmed up to normal operating temperature, drive vehicle until “ATF
TEMP SEN” (CVT fluid temperature sensor signal) indicates more than 60°C (140°F).

Electrical load: Not applied
–Rear window defogger switch, air conditioner switch, lighting switch are OFF. Steering wheel is straight
ahead.

Engine speed: Idle
Inspection ProcedureBBS004YK
NOTE:
Perform “DATA MONITOR (SPEC)” mode in maximum scale display.
1. Perform EC-381, "
Basic Inspection" .
2. Confirm that the testing conditions indicated above are met.
3. Select “B/FUEL SCHDL”, “A/F ALPHA-B1”, “A/F ALPHA-B2”
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-441, "

REPAIRING PROCEDURE
1. Wipe broken heat wire and its surrounding area with a cloth
dampened in alcohol to clean.
2. Apply a small amount of conductive silver composition to tip of
drawing pen.
Shake silver composition container before use.
3. Place ruler on glass along broken line. Deposit conductive silver
composition on break with drawing pen. Slightly overlap existing
heat wire on both sides [preferably 5 mm (0.20 in)] of the break.
4. After repair has been completed, check repaired wire for conti-
nuity. This check should be performed 10 minutes after silver
composition is deposited.
Do not touch repaired area while test is being conducted.
5. Apply a constant stream of hot air directly to the repaired area
for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area and
hot air outlet.
If a heat gun is not available, let the repaired area dry for 24
hours.
