P0600

This circuit line (LAN) controls the smooth shifting up and down of A/T during the hard acceleration/deceleration. Pulse signals are exchanged between ECM and TCM (P0600).
This circuit line is also used to communicate malfunction information related to A/T (Automatic Transmission) is transferred through the line (LAN circuit) from TCM to ECM (P1605).
Be sure to erase the malfunction information such as DTC not only in TCM but also ECM after the AFT related repair.
