DTC
|
B2283
|
Vehicle Speed Sensor Malfunction
|
DESCRIPTION
DTC B2282 is stored when a mismatch between the vehicle speed signal from the direct line sent by the combination meter and the vehicle speed signal sent via CAN communication is detected.
DTC B2283 is stored when a malfunction in the vehicle speed sensor is detected.
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 changes to on (IG).
-
When the battery cable is disconnected and reconnected, the power source returns to the mode it was in before the battery cable was disconnected.

B2282
|
Mismatch between the vehicle speed signal from the direct line sent by the combination meter and the vehicle speed signal sent via CAN communication (1-trip detection logic*).

CAN communication system
-
Power management control ECU
-
Meter/gauge system

|
Drive the vehicle for 20 seconds at a vehicle speed of 25 km/h (16 mph) or more, and then drive the vehicle at a vehicle speed that is less than 5 km/h (3 mph) for 20 seconds.
|
B2283
|
Either condition is met (vehicle speed sensor malfunction is detected) (1-trip detection logic*):
-
Vehicle speed signal malfunction detection 1: Large decrease in speed is detected.
-
Vehicle speed signal malfunction detection 2: Engine speed-linked detection.
|
-
*: Only output while a malfunction is present and the engine switch is on (IG)

Fail-safe Function when Malfunction Detected
|
B2282
|
-
When the signal from the direct line or CAN communication is malfunctioning and indicates no vehicle speed, there is no effect on vehicle behavior.
-
When the signal from the direct line or CAN communication is malfunctioning and indicates that the vehicle is moving, the power source mode cannot be turned from on (IG) to off.
|
-
|
B2283
|
-
If the engine switch is pressed while the vehicle is being driven, the engine switch turns off (the engine stops).
-
When the key is inside the vehicle, the engine does not start even though an engine start operation is performed.
|
Steering lock motor operation is prohibited.
