DESCRIPTION AND POSSIBLE CAUSES

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
