AUTOMATIC TRANSAXLE SYSTEM TERMINALS OF ECU

  1. TCM

    C205631E05
    Tip:

    The standard voltage at each TCM terminal is shown in the table below.

    In the table, first follow the information under "Condition". Look under "Terminal No. (Symbol)" for the terminals to inspect. The standard voltage between the terminals is shown under "Specified Condition".

    Use the illustration above as a reference for the TCM terminals.
