DTC U0001:88/U0100:00/U0131:00/U0155:00/U0214:00 [BLIND SPOT MONITORING (BSM)]

id0902i3035700

Description	•  U0001:88 ―  Module communication error (HS-CAN) •  U0100:00 ―  Communication error with PCM •  U0131:00 ―  Communication error with EPS control module •  U0155:00 ―  Communication error with instrument cluster •  U0214:00 ―  Communication error with start stop unit
Detection condition	•  U0001:88 ―  BSM control module detected a CAN bus communication line (HS-CAN) malfunction for 0.4 s or more. •  U0100:00 ―  BSM control module cannot receive a CAN signal from the PCM for 1.5 s or more. •  U0131:00 ―  BSM control module cannot receive a CAN signal from the EPS control module for 1.5 s or more. •  U0155:00 ―  BSM control module cannot receive a CAN signal from the instrument cluster. •  U0214:00 ―  BSM control module cannot receive a CAN signal from the start stop unit for 1.5 s or more.
Fail-safe function	•  U0001:88 ―  Blind spot monitoring (BSM) system is stopped. •  U0100:00 ―  Blind spot monitoring (BSM) system is stopped. •  U0131:00 ―  Blind spot monitoring (BSM) system is stopped. •  U0155:00 ―  Blind spot monitoring (BSM) system is stopped. •  U0214:00 ―  Blind spot monitoring (BSM) system is stopped.
Possible cause	•  Malfunction in CAN bus communication line •  Malfunction in CAN communication line between PCM and BSM control module •  Malfunction in CAN communication line between EPS control module and BSM control module •  Malfunction in CAN communication line between instrument cluster and BSM control module •  Malfunction in CAN communication line between start stop unit and BSM control module
