DTC B2282: Vehicle Speed Signal Malfunction; DTC B2283: Vehicle Speed Sensor Malfunction [08/2015 - 08/2019]: Description
The power management control ECU and the combination meter are connected by a cable and the CAN communication lines. This DTC is stored when the vehicle speed signal information from the cable and the vehicle speed signal information from the CAN communication line are inconsistent.
HINT:
When the power management control ECU is replaced with a new one and the cable is connected to the negative (-) battery terminal, the power source mode is reset to on (IG). When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2282 | The vehicle speed signal information from the cable and the vehicle speed signal information from the CAN communication line are inconsistent. |
|
The skid control ECU converts signals from the speed sensor into 4-pulse signals and sends them to the combination meter. After these signals are converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, they are then transmitted to the power management control ECU. The power management control ECU determines the vehicle speed based on the frequencies of these pulse signals.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2283 | Both conditions are met:

HINT:
- A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter. The signal is changed to a pulse signal at the transistor in the combination meter. Each ECU controls its respective system based on the pulse signal.
- If a short circuit occurs in an ECU, all systems related to the components in the diagram above will not operate normally.
