System DescriptionNCEC0560The malfunction information related to CVT is transferred through the line (circuit) from TCM (Transmission
Control Module) to ECM. Therefore, be sure to erase the malfunction information such as DTC not only in TCM
(Transmission Control Module) but also ECM after the CVT related repair.
ECM Terminals and Reference ValueNCEC0561Specification data are reference values and are measured between each terminal and 48 (ECM ground).

seconds before conducting the next test.
With CONSULT-II
1) Turn ignition switch ªONº.
2) Select ªDATA MONITORº mode with CONSULT-II.
3) Start engine and let it idle for at least 40 seconds.
4) If 1st trip DTC is detected, go to ªDiagnostic Procedureº, EC-
SR-297.

5) If 1st trip DTC is detected, go to ªDiagnostic Procedureº, EC-
SR-301.
Overall Function CheckNCEC0429Use this procedure to check the overall function of the park/neutral
position switch circuit. During this check, a 1st trip DTC might not
be confirmed.
Without CONSULT-II
1) Turn ignition switch ªONº.
2) Check voltage between ECM terminal 42 (PNP switch signal)
and body ground under the following conditions.
Condition (Gear position) Voltage (V) (Known good data)
ªPº (CVT only) and ªNº position Approx. 0
Except the above position BATTERY VOLTAGE (11 - 14V)
