AUTOMATIC TRANSAXLE SYSTEM TERMINALS OF ECU


  1. TCM

    A01EVKVE14

    Tech Tips

    Each TCM terminal standard voltage is shown in the table below.

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

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