DTC B2282: Vehicle Speed Signal Malfunction; 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.

DTC Code	DTC Detection Condition	Trouble Area	DTC Output Confirmation Operation
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 Harness or connector	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)

VEHICLE CONDITION AND FAIL-SAFE FUNCTION WHEN MALFUNCTION DETECTED

DTC Code	Vehicle Condition when Malfunction Detected	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.
