DTC U0401-68: Error Signal Received From ECM (E-SKYACTIV PHEV)/Pcm (Except E-SKYACTIV PHEV), Electronically Controlled Brake Unit/DSC HU/Cm, Instrument Cluster, Or Body Control Module (BCM)

U0401-68: (VCM) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	Error signal received from ECM (e-SKYACTIV PHEV)/PCM (except e-SKYACTIV PHEV), electronically controlled brake unit/DSC HU/CM, instrument cluster, or body control module (BCM)
Detection condition	When any of the following conditions is met. The vehicle control module (VCM) receives the error signal from the ECM (e-SKYACTIV PHEV)/PCM (except e-SKYACTIV PHEV). The vehicle control module (VCM) detects that the brake signals between the following modules did not match while the brake pedal is operated. ECM (e-SKYACTIV PHEV)/PCM (except e-SKYACTIV PHEV) Electronically controlled brake unit/DSC HU/CM Body control module (BCM) The vehicle control module (VCM) detects that a fail-safe is operated based on a deceleration request while the vehicle is being driven.
Fail-safe	(See DTC TABLE [VCM] .)
Possible cause	Internal malfunction related DTCs are stored in the following modules. Vehicle control module (VCM) (See DTC TABLE [VCM] .) Body control module (BCM) (See DTC TABLE [BCM] .) DTCs are stored in the following modules. ECM (e-SKYACTIV PHEV)/PCM (except e-SKYACTIV PHEV) (See DTC TABLE [PCM (SKYACTIV-G)] .) (See DTC TABLE [PCM (SKYACTIV-G 2.5T)] .) Electronically controlled brake unit/DSC HU/CM (See DTC TABLE [DSC] .) Body control module (BCM) (See DTC TABLE [BCM] .) Cruise control switch malfunction (Refer to CRUISE CONTROL SWITCH INSPECTION in service information.) ECM (e-SKYACTIV PHEV)/PCM (except e-SKYACTIV PHEV) malfunction (Refer to PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION)] , or PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.5T] in service information.) Electronically controlled brake unit/DSC HU/CM malfunction (Refer to [ELECTRONICALLY CONTROLLED BRAKE UNIT REMOVAL/INSTALLATION] in service information.) (Refer to DSC HU/CM REMOVAL/INSTALLATION in service information.) Vehicle control module (VCM) malfunction (built into body control module (BCM)) (Refer to BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION in service information.)
Repeatability verification procedure	Clear the DTC recorded in the memory. (See CLEARING DTC .) Operate the brake pedal.
