DTC U0029: General Description

Courtesy of HONDA, U.S.A., INC.

The controller area network (CAN) transmits/receives pulsing signals to/from the control modules simultaneously by using two signal lines (H line and L line). When the powertrain control module (PCM) cannot send the signals via the F-CAN lines for a set time, the PCM detects a malfunction and stores a DTC.
