DTC Advanced Diagnostics: U0302(AT): General Description
The transmission control module (TCM) and the powertrain control module (PCM) uses communication line (F-CAN lines) to transmit/receive multiple signals simultaneously. When the software version in the TCM and software version sent from the PCM via the F-CAN lines are mismatched for a set time, the TCM detects a malfunction and stores a DTC.
