CONSULT-II Reference Value in Data MonitorEBS00BMS
Remarks:
lSpecification data are reference values. MODE 4 CLEAR DIAG INFOThis mode can clear all emission-related diagnostic information. This includes:
lClear number of diagnostic trouble codes (MODE 1)
lClear diagnostic trouble codes (MODE 3)
lClear trouble code for freeze frame data (MODE 1)
lClear freeze frame data (MODE 2)
lReset status of system monitoring test (MODE 1)
lClear on board monitoring test results (MODE 6 and 7)
MODE 6 (ON BOARD TESTS)This mode accesses the results of on board diagnostic monitoring tests of specific com-
ponents/systems that are not continuously monitored.
MODE 7 (ON BOARD TESTS)This mode enables the off board test drive to obtain test results for emission-related pow-
ertrain components/systems that are continuously monitored during normal driving condi-
tions.
MODE 8 — This mode is not applicable on this vehicle.
MODE 9 (CALIBRATION ID)This mode enables the off-board test device to request specific vehicle information such
as Vehicle Identification Number (VIN) and Calibration IDs. Diagnostic test mode Function

TROUBLE DIAGNOSIS
lSpecification data are output/input values which are detected or supplied by the ECM at the connector.
* Specification data may not be directly related to their components signals/values/operations.
i.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the specification data in
spite of the ignition timing not being adjusted to the specification data. This IGN TIMING monitors the data calculated by the ECM
according to the signals input from the camshaft position sensor and other ignition timing related sensors.
lIf the real-time diagnosis results are NG and the on board diagnostic system results are OK when diagnosing the mass air flow sen-
sor, first check to see if the fuel pump control circuit is normal.

DescriptionEBS00B1J
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:
lB/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board cor-
rection)
lA/F ALPHA-B1 (The mean value of air-fuel ratio feedback correction factor per cycle)
lMAS A/F SE-B1 (The signal voltage of the mass air flow sensor)
Testing ConditionEBS00B1K
lVehicle driven distance: More than 5,000 km (3,017 miles)
lBarometric pressure: 98.3 - 104.3 kPa (0.983 - 1.043 bar, 1.003 - 1.064 kg/cm2, 14.25 - 15.12 psi)
lAtmospheric temperature: 20 - 30°C(68-86°F)
lEngine coolant temperature: 75 - 95°C (167 - 203°F)
lTransmission: Warmed-up*1
lElectrical load: Not applied*2
lEngine speed: Idle
*1: For A/T models with CONSULT-II, 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).
For A/T models without CONSUT-II and M/T models, after the engine is warmed up to normal operating tem-
perature, drive vehicle for 5 minutes.
*2: Rear window defogger switch, air conditioner switch, lighting switch are “OFF”. Steering wheel is straight
ahead.
Inspection ProcedureEBS00B1L
NOTE:
Perform “DATA MONITOR (SPEC)” mode in maximum scale display.
1. PerformEC-412, "
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 toEC-104, "
Diagnostic Procedure".
