id060230818200

DTC	U0001:88	CAN communication: module communication error
	U0100:00	CAN communication: communication error to PCM
	U0121:00	CAN communication: communication error to DSC HU/CM
	U0155:00	CAN communication: communication error to instrument cluster
	U0214:00	CAN communication: communication error to start stop unit
DETECTION CONDITION		•  U0001:88 ―  Error detected in CAN bus communication line with CAN connection modules •  U0100:00 ―  Communication error to PCM is detected in CAN communication •  U0121:00 ―  Communication error to DSC HU/CM is detected in CAN communication •  U0155:00 ―  Communication error to instrument cluster is detected in CAN communication •  U0214:00 ―  Communication error to start stop unit is detected in CAN communication
FAIL-SAFE FUNCTION		•  U0001:88 ―  Power steering malfunction indicator light does not Illuminate ―  EPS motor current control enabled •  U0100:00 ―  Power steering malfunction indicator light Illuminates ―  EPS motor current control is maintained by gradually changing the controlled vehicle speed and setting it to specified speed •  U0121:00, U0155:00, U0214:00 ―  Power steering malfunction indicator light does not Illuminate ―  EPS motor current control enabled
POSSIBLE CAUSE		•  CAN communication line malfunction •  CAN communication line malfunction with PCM •  CAN communication line malfunction with DSC HU/CM •  CAN communication line malfunction with instrument cluster •  CAN communication line malfunction with start stop unit •  Poor connection at each connector
