Description

INFOID:0000000004211350

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

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)

Component Function Check

INFOID:0000000004211351

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 (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 (After the engine is warmed up to normal operating temperature, drive vehicle for

5 minutes.)

• Engine speed: Idle

>> GO TO 2.

2.

PERFORM “SPEC” OF “DATA MONITOR” MODE

With CONSULT-III

NOTE:

Perform “SPEC” in “DATA MONITOR” mode in maximum scale display.

1. Lift up the vehicle.

2. Perform 

EC-11, "BASIC INSPECTION : Special Repair Requirement"

.

3. Turn ignition switch ON (READY).

4. Depressed the accelerator pedal and keep it.

5. Shift the selector lever to N position with engine running.

CAUTION:

Never leave the selector lever in the N position for a long period of time. In the N position, the

engine operates but electricity cannot be generated.

6. Select “B/FUEL SCHDL”, “A/F ALPHA-B1” and “MAS A/F SE-B1” in “SPEC” of “DATA MONITOR” mode

with CONSULT-III.

7. Make sure that monitor items are within the SP value.

8. Shift the selector lever to P position.
Is the inspection result normal?

YES

>> END

NO
