DTC B2009-92: Communication Error With Body Control Module (BCM), Dash-Electrical Supply Unit, Door-Electrical Supply Unit Or ECM (E-SKYACTIV PHEV)/Pcm (Except E-SKYACTIV PHEV)
B2009:92 (DASH_ESU) DETECTION CONDITION AND POSSIBLE CAUSE
| System malfunction location |
Communication error with body control module (BCM), dash-electrical supply unit, door-electrical supply unit or ECM (e-SKYACTIV PHEV)/PCM (except e-SKYACTIV PHEV) |
| Detection condition |
- The dash-electrical supply unit detects any of the following conditions.
- The climate control unit cannot receive CAN signal from the body control module (BCM).
- The climate control unit cannot receive CAN signal from the dash-electrical supply unit.
- The climate control unit cannot receive CAN signal from the door-electrical supply unit.
- The climate control unit cannot receive CAN signal from the ECM (e-SKYACTIV PHEV)/PCM (except e-SKYACTIV PHEV).
|
| Fail-safe |
|
| Possible cause |
- Malfunction in CAN communication line between body control module (BCM) and climate control unit
- Malfunction in CAN communication line between dash-electrical supply unit and climate control unit
- Malfunction in CAN communication line between door-electrical supply unit and climate control unit
- Malfunction in CAN communication line between ECM (e-SKYACTIV PHEV)/PCM (except e-SKYACTIV PHEV) and climate control unit
