Description	•  U0001:88 ―  Module communication error (HS-CAN) •  U0100:00 ―  Communication error with PCM •  U0101:00 ―  Communication error with TCM •  U0121:00 ―  Communication error with ABS HU/CM or DSC HU/CM •  U0151:00 ―  Communication error with SAS control module •  U0155:00 ―  Communication error with instrument cluster •  U0214:00 ―  Communication error with start stop unit •  U023A:00 ―  Communication error with forward sensing camera (FSC)
Detection condition	•  U0001:88 ―  Front body control module (FBCM) detects a CAN bus communication line (HS-CAN) malfunction 10 times continuously. •  U0100:00 ―  Front body control module (FBCM) could not receive the CAN signal from the PCM for 5 s or more. •  U0101:00 ―  Front body control module (FBCM) could not receive the CAN signal from the TCM for 5 s or more. •  U0121:00 ―  Front body control module (FBCM) could not receive the CAN signal from the ABS HU/CM or DSC HU/CM for 5 s or more. •  U0151:00 ―  Front body control module (FBCM) could not receive the CAN signal from the SAS control module for 5 s or more. •  U0155:00 ―  Front body control module (FBCM) could not receive the CAN signal from the instrument cluster for 5 s or more. •  U0214:00 ―  Front body control module (FBCM) could not receive the CAN signal from the start stop unit for 5 s or more. •  U023A:00 ―  Front body control module (FBCM) could not receive the CAN signal from the forward sensing camera (FSC) for 5 s or more.
Fail-safe function	•  U0001:88 ―  Control at the default signal value after holding the previous value for 5 s. •  U0100:00 ―  Control at the default signal value after holding the previous value for 5 s. •  U0101:00 ―  Control at the default signal value after holding the previous value for 5 s. •  U0121:00 ―  Control at the default signal value after holding the previous value for 5 s. •  U0151:00 ―  Control at the default signal value after holding the previous value for 5 s. •  U0155:00 ―  Control at the default signal value after holding the previous value for 5 s. •  U0214:00 ―  Control at the default signal value after holding the previous value for 5 s. •  U023A:00 ―  Control at the default signal value after holding the previous value for 5 s.
Possible cause	•  Malfunction in CAN bus communication line •  Malfunction in CAN line between the PCM and front body control module (FBCM) •  Malfunction in CAN line between the TCM and front body control module (FBCM) •  Malfunction in CAN line between the ABS HU/CM or DSC HU/CM and front body control module (FBCM) •  Malfunction in CAN line between the SAS control module and front body control module (FBCM) •  Malfunction in CAN line between the instrument cluster and front body control module (FBCM) •  Malfunction in CAN line between the start stop unit and front body control module (FBCM) •  Malfunction in CAN line between the forward sensing camera (FSC) and front body control module (FBCM)
