    • Module communication error (HS-CAN) 
  • U0100:00 
    • Communication error with PCP 
  • U0101:00 
    • Communication error with TCM 
  • 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  .
  • 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  .
  • 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 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)
