A/T Communication Line

System Description
This circuit line (LAN) is used to control the smooth shifting up and down of A/T during the hard acceleration/deceleration.

Pulse signals are exchanged between ECM and TCM (Transmission Control Module).

Be sure to erase the malfunction information such as DTC not only in TCM but also ECM after the A/T related repair.
