DTC Advanced Diagnostics: P0864: General Description
The controller area network (CAN) transmits/receives pulsing signals to/from the control modules simultaneously by using two signal lines (F-CAN_H and F-CAN_L). When the information is not sent from the transmission control module (TCM) via the F-CAN lines and this condition continues for a specified time or when the information sent from the TCM is abnormal and this condition continues for a specified cycle, the powertrain control module (PCM) detects a malfunction and stores a DTC.
