DTC U0100-00: Can Communication: Communication Error To Pcm

WARNING: <<High voltage>>

• If the necessary measures are not taken before servicing an electric vehicle, it could cause electrical shock and result in serious injury or, in the worst case, death. Before servicing the electric vehicle, refer to [HIGH VOLTAGE SERVICE CAUTIONS ] in the general information and implement the necessary measures. (Refer to [HIGH VOLTAGE SERVICE CAUTIONS ] in service information).

U0100-00: (OBC) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	CAN communication: communication error to PCM
Detection condition	Communication error between the PCM and battery charge control module continues.
Fail-safe	Stops charging
Possible cause	WARNING: <<High voltage>> If necessary measures such as wearing the correct protective gear are not taken when inspecting or removing/installing the high voltage parts, it could cause electrical shock and result in serious injury or, in the worst case, death. Before inspecting or removing/installing the high voltage parts, refer to [HIGH VOLTAGE SERVICE CAUTIONS ] in the general information and [High Voltage Part Inspection and Removal/Installation Notes] of the high voltage system service cautions and implement the necessary measures and preparations. (Refer to [HIGH VOLTAGE SERVICE CAUTIONS ] in service information). (Refer to [HIGH VOLTAGE SYSTEM SERVICE CAUTIONS ] in service information). Wear insulated gloves when working on a high voltage system. DTCs are stored in the following modules. PCM (See DTC TABLE [PCM (e-SKYACTIV PHEV)] .) Battery charge control module (other than U0100: 00) (See DTC TABLE [OBC] ). Malfunction in wiring harness (including connector/terminal) between PCM and battery charge control module (See CIRCUIT INSPECTION .) (See CONNECTOR INSPECTION .) PCM malfunction (Refer to [PCM REMOVAL/INSTALLATION ] in service information). Battery charge control module malfunction (Refer to [ONBOARD CHARGER REMOVAL/INSTALLATION ] in service information).
Repeatability verification procedure	Clear the DTC recorded in the memory. (See CLEARING DTC .) Perform charging using charging equipment other than that used when the DTC was output.
