ECM Terminals and Reference Value (Cont’d)
EC-140
Description
NLEC1271
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 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 Condition
NLEC1272
+
Vehicle driven distance: More than 5,000 km (3,100 miles)
+
Barometric pressure: 101.3 kPa (760.0 mmHg, 29.92 inHg)
±
3 kPa (22.5 mmHg, 0.89 inHg)
+
Atmospheric temperature: 20 - 30°C (68 - 86°F)
+
Engine coolant temperature: 75 - 95°C (167 - 203°F)
+
Transmission: Warmed-up*1
+
Electrical load: Not applied*2
+
Engine speed: Idle
*1: For M/T models, drive vehicle for 5 minutes after the engine is warmed up to normal operating tempera-
ture.
*2: Rear window defogger switch, air conditioner switch, lighting switch are “OFF”. Cooling fans are not oper-
ating. Steering wheel is straight ahead.

Inspection Procedure
NLEC1273
NOTE:
Perform “DATA MONITOR (SPEC)” mode in maximum scale dis-
play.
1.
Perform “Basic Inspection”, EC-99.
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 “Diagnostic Procedure”, EC-142.

Description
NLEC0045
Intermittent incidents (I/I) may occur. In many cases, the problem resolves itself (the part or circuit function
returns to normal without intervention). It is important to realize that the symptoms described in the custom-
er’s complaint often do not recur on DTC (1st trip) visits. Realize also that the most frequent cause of I/I
occurrences is poor electrical connections. Because of this, the conditions under which the incident occurred
may not be clear. Therefore, circuit checks made as part of the standard diagnostic procedure may not indi-
cate the specific problem area.
COMMON I/I REPORT SITUATIONS

Situation
II
The CONSULT-II is used. The SELF-DIAG RESULTS screen shows time data other than “0” or
“1t”.
III
The symptom described by the customer does not recur.
IV
(1st trip) DTC data does not appear during the DTC Confirmation Procedure.
VI
The Diagnostic Procedure for PXXXX does not indicate the problem area.

ECM TERMINALS AND REFERENCE VALUE
NLEC0048
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM’s transistor. Use a ground other than ECM terminals, such as the ground.
