| Detection condition |
- U0001:88
- The front body control module (FBCM) detects CAN bus communication line (HS-CAN) malfunction 10 times
continuously.
- U0100:00
- The front body control module (FBCM) could not receive CAN signal from the PCM for 5 s or more.
- U0101:00
- The front body control module (FBCM) could not receive CAN signal from the TCM for 5 s or more.
- U0121:00
- The front body control module (FBCM) could not receive CAN signal from the DSC HU/CM for 5 s or more.
- U0151:00
- The front body control module (FBCM) could not receive CAN signal from the SAS control module for 5 s or more.
- U0155:00
- The front body control module (FBCM) could not receive CAN signal from the instrument cluster for 5 s or more.
- U0214:00
- The front body control module (FBCM) could not receive CAN signal from the start stop unit for 5 s or more.
- U023A:00
- The front body control module (FBCM) could not receive CAN signal from the forward sensing camera (FSC) for 5 s or more.
- U0515:00
- The front body control module (FBCM) could not receive CAN signal from the SAS control module for 5 s or more.

| Fail-safe |
- 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
- U0515:00
- 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 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)
- Malfunction in CAN line between the SAS control module and front body control module (FBCM)
