Diagnostic Procedure (Cont'd)
EC-927

System DescriptionNLEC1641The 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 ValueNLEC1642Specification 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.

DTC Confirmation ProcedureNLEC1644NOTE:
If ªDTC CONFIRMATION PROCEDUREº has been previously
conducted, always turn ignition switch ªOFFº and wait at least 10
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-930.
With GST
Follow the procedure ªWith CONSULT-IIº above.
