5A-60 Automatic Transmission/Transaxle:
Inspection of TCM and Its Circuits
S6RW0C5104039
TCM and its circuits can be checked at TCM wiring connectors by measuring voltage and resistance.
CAUTION
!
TCM cannot be checked by itself, it is strictly prohibited to connect voltmeter or ohmmeter to TCM with
connector disconnected from it.
Inspection
1) Remove TCM (1) from vehicle referring to “Transmission Control Module (TCM) Removal and Installation”.
2) Connect TCM connectors (2) to TCM.
3) Check voltage and/or pulse signal at each terminal of connectors connected using voltmeter (3) and oscilloscope
(4).
NOTE
• As each terminal voltage is affected by battery voltage, confirm that it is 11 V or more when ignition
switch is ON.
• Voltage with asterisk (*) cannot be measured by voltmeter because it is pulse signal. Check it with
oscilloscope if necessary.
