U129E ACURA MeaningThe 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 Powertrain Control Module (PCM) does not receive the signals from the Keyless Access/TPMS Control Unit via the F-CAN lines for a set time, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
