Diagnostic ProcedureNCEC0332
1 RETIGHTEN GROUND SCREWS
1. Turn ignition switch ªOFFº.
2. Loosen and retighten engine ground screws.
©GO TO 2.
2 CHECK INPUT SIGNAL CIRCUIT
1. Disconnect crankshaft position sensor (OBD) and ECM harness connectors.
SEF226X2. Check continuity between ECM terminal 65 and crankshaft position sensor (OBD) harness connector terminal 1.
Refer to wiring diagram.
Continuity should exist.
3. Also check harness for short to ground and short to power.
OK or NG
OK©GO TO 4.

Page 1095 of 2267

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).

DTC Confirmation ProcedureNCEC0563NOTE:
If ªDTC CONFIRMATION PROCEDUREº has been previously
conducted, always turn ignition switch ªOFFº and wait at least 9
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.
With GST
Follow the procedure ªWith CONSULT-IIº above.
