DTC U0001:88/U0100:00/U0101:00/U0121:00/U0151:00/U0155:00/U0214:00/U023A:00 [FRONT BODY CONTROL MODULE (FBCM)]

id0902p2636000

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 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 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 ―  Forcibly turn on the headlights and TNS (parking lights) when the ignition is switched ON (engine off or on), and operate the windshield wiper at low speed only when the windshield wiper switch is at LO or HI. •  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 ―  Not applicable •  U0155:00 ―  After maintaining the previous value for 5 s, forcibly turn on the headlights and TNS (parking lights) when the ignition is switched ON (engine off or on), and operate the windshield wiper at low speed only when the windshield wiper switch is at LO or HI. ―  Control at the default signal value under any condition other than the above. •  U0214:00 ―  Control at the default signal value after holding the previous value for 5 s. •  U023A:00 ―  Not applicable
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 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)
