TCM terminal data are reference values, measured between each terminal and ground.
Diagnostic ProcedureUCS005ZH
1. CHECK CVT FLUID TEMPERATURE SENSOR SIGNAL
With CONSULT-II
1. Start engine.
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.
3. Read out the value of “ATF TEMP SEN”.
Without CONSULT-II
1. Start engine.
2. Check voltage between TCM connector terminals.
3. Turn ignition switch OFF.
4. Disconnect TCM connector.
5. Check if there is continuity between connector terminal and
ground.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
2. CHECK CVT FLUID TEMPERATURE SENSOR CIRCUIT
