CONSULT-II Reference Value in Data Monitor
Mode
NEEC0042Remarks:
+Specification data are reference values.
+Specification 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. Specification data might be displayed even when igni-
tion timing is not adjusted to specification. This IGN TIMING monitors the data calculated by the ECM according to the input signals
from the camshaft position sensor and other ignition timing related sensors.)

DTC Confirmation ProcedureNEEC0184NOTE:
If ªDTC Confirmation Procedureº has been previously conducted,
always turn ignition switch OFF and wait at least 5 seconds before
conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that bat-
tery voltage is in between 10.5V at idle.
SEF175Y
With CONSULT-II
1) Turn ignition switch ON and select ªDATA MONITORº mode
with CONSULT-II.
2) Start engine and drive vehicle at a speed of more than 70 km/h
(43 MPH) for 2 consecutive minutes.
3) If 1st trip DTC is detected, go to ªDiagnostic Procedureº,
EC-3141.
With GST
1) Start engine.
2) Drive vehicle at a speed of more than 70 km/h (43 MPH) for 2
consecutive minutes.
3) Stop vehicle and let engine idle for at least 6 seconds.
4) Turn ignition switch OFF and wait at least 10 seconds.
5) Start engine.
6) Drive vehicle at a speed of more than 70 km/h (43 MPH) for 2
consecutive minutes
7) Stop vehicle and let engine idle for at least 6 seconds.
8) Select ªMODE 3º with GST.
9) If DTC is detected, go to ªDiagnostic Procedureº, EC-3141.
When using GST, ªDTC Confirmation Procedureº should be
performed twice as much as when using CONSULT-II because
GST cannot display MODE 7 (1st trip DTC) concerning this
diagnosis. Therefore, using CONSULT-II is recommended.

PROCEDURE FOR MALFUNCTION BNEEC0054S04With CONSULT-II
1) Turn ignition switch ON.
2) Start engine and warm it up to normal operating temperature.
If engine cannot be started, go to ªDiagnostic Procedureº,
EC-3147.
3) Select ªDATA MONITORº mode with CONSULT-II.
4) Check the voltage of ªMAS A/F SE-B1º with ªDATA MONITORº.
5) Increases engine speed to about 4,000 rpm.
6) Monitor the linear voltage rise in response to engine speed
increases.
If NG, go to ªDiagnostic Procedureº, EC-3147.
If OK, go to following step.
7) Maintain the following conditions for at least 10 consecutive
seconds.
ENG SPEED More than 2,000 rpm
THRTL POS SEN More than 3V
Selector lever Suitable position
Driving location Driving vehicle uphill (Increased engine load)
will help maintain the driving conditions
required for this test.

Overall Function CheckNEEC0055Use this procedure to check the overall function of the mass air flow
sensor circuit. During this check, a 1st trip DTC might not be con-
firmed.
PROCEDURE FOR MALFUNCTION BNEEC0055S01With GST
1) Turn ignition switch ON.
2) Start engine and warm it up to normal operating temperature.
3) Select ªMODE 1º with GST.
4) Check the mass air flow sensor signal with ªMODE 1º.
5) Check for linear mass air flow rise in response to increases to
about 4,000 rpm in engine speed.
6) If NG, go to ªDiagnostic Procedureº, EC-3147.
