- HINT:
- Each TCM terminal's standard voltage is shown in the table below.
- In the table, first follow the information under "Condition". Look under "Symbols (Terminal No.)" for the terminals to be inspected. The standard voltage between the terminals is shown under "Specific Condition".
- Use the illustration above as a reference for the TCM terminals.
