Description	•  U0001:88 ―  Module communication error (HS-CAN) •  U0100:00 ―  Communication error with PCM •  U0101:00 ―  Communication error with TCM •  U0104:00 ―  Communication error with radar unit •  U0155:00 ―  Communication error with instrument cluster •  U0156:00 ―  Communication error with connectivity master unit (CMU) •  U0235:00 ―  Communication error with laser sensor •  U023A:00 ―  Communication error with forward sensing camera (FSC) •  U0298:00 ―  Communication error with DC-DC converter (i-ELOOP)
Detection condition	•  U0001:88 ―  Active driving display detects a CAN bus communication line (HS-CAN) malfunction. •  U0100:00 ―  Active driving display cannot receive the CAN signal from the PCM. •  U0101:00 ―  Active driving display cannot receive the CAN signal from the TCM for 1 s or more. •  U0104:00 ―  Active driving display cannot receive the CAN signal from the radar unit for 1 s or more. •  U0155:00 ―  Active driving display cannot receive the CAN signal from the instrument cluster for 5 s or more. •  U0156:00 ―  Active driving display cannot receive the CAN signal from the connectivity master unit (CMU) for 5 s or more. •  U0235:00 ―  Active driving display cannot receive the CAN signal from the laser sensor for 1 s or more. •  U023A:00 ―  Active driving display cannot receive the CAN signal from the forward sensing camera (FSC) for 1 s or more. •  U0298:00 ―  Active driving display cannot receive the CAN signal from the DC-DC converter (i-ELOOP) for 5 s or more.
Fail-safe	•  U0001:88 ―  Not applicable •  U0100:00 ―  Not applicable •  U0104:00 ―  Not applicable •  U0155:00 ―  Not applicable •  U0156:00 ―  Not applicable •  U0235:00 ―  Inhibits the smart city brake support control. ―  Warning message related to the smart city brake support is displayed in the center display. (with center display) •  U023A:00 ―  Not applicable •  U0298:00 ―  Not applicable
Possible cause	•  Malfunction in CAN bus communication line •  Malfunction in CAN line between PCM and active driving display •  Malfunction in CAN line between TCM and active driving display •  Malfunction in CAN line between radar unit and active driving display •  Malfunction in CAN line between connectivity master unit (CMU) and active driving display •  Malfunction in CAN line between instrument cluster and active driving display •  Malfunction in CAN line between laser sensor and active driving display •  Malfunction in CAN line between forward sensing camera (FSC) and active driving display •  Malfunction in CAN line between DC-DC converter (i-ELOOP) and active driving display
