Precaution in Diagnosing Trouble
• Don’t disconnect couplers from TCM, battery cable from battery, TCM ground wire harness from engine or
main fuse before checking the diagnosis information stored in TCM memory.
Such disconnection will clear memorized information in TCM memory.
• Using scan tool the diagnostic information stored in TCM memory can be checked and cleared as well.
Before its use, be sure to read Operator’s (instruction) Manual supplied with it carefully to have good under-
standing of its functions and usage.
• Be sure to read “Precautions for Electrical Circuit Service” in Section 0A before inspection and observe what
is written there.
• TCM and/or ECM replacement
– When substituting a known-good TCM and/or ECM, check that all relays and actuators have resistance of
specified value.
Neglecting this check may result in damage to good TCM and/or ECM.
• Communication of ECUs, ECM and TCM, is established by CAN (Computer Area Network).
Therefore, handle CAN communication line with care referring to “Precaution” described in Section 0A.
