DTC U0010-88; U0100-00; U0155-00; U0214; Module Communication Errors: Notes
WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
DETECTION CONDITION & POSSIBLE CAUSE
| Description |
- U0010:88
- Module communication error (MS-CAN)
- U0100:00
- Communication error with PCM
- U0155:00
- Communication error with instrument cluster
- U0214:00
- Communication error with start stop unit
|
| Detection condition |
- U0010:88
- Blind spot monitoring (BSM) control module detected a CAN bus communication line (MS-CAN) malfunction for 1.4 s or more.
- U0100:00
- Blind spot monitoring (BSM) control module cannot receive a CAN signal from the PCM for 5 s or more.
- U0155:00
- Blind spot monitoring (BSM) control module cannot receive a CAN signal from the instrument cluster.
- U0214:00
- Blind spot monitoring (BSM) control module cannot receive a CAN signal from the start stop unit for 5 s or more.
|
| Fail-safe |
- U0010:88
- Blind spot monitoring (BSM) system is stopped.
- U0100:00
- 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 blind spot monitoring (BSM) control module
- Instrument cluster communication error (vehicle speed signal is not sent via instrument cluster from PCM)
- Malfunction in CAN communication line between instrument cluster and blind spot monitoring (BSM) control module
- Malfunction in CAN communication line between start stop unit and blind spot monitoring (BSM) control module
- Instrument cluster communication error (turn switch signal is not sent via instrument cluster from start stop unit)
