B2282
|
Vehicle Speed Signal Malfunction
|
The vehicle speed signal sent from the skid control ECU via direct line and sent from the combination meter assembly via CAN communication do not match. (1-trip detection logic*)
|
-
Meter/gauge system
-
Vehicle stability control system
-
Certification ECU (smart key ECU assembly)
-
Wire harness or connector
|
DTC Output Confirmation Operation:
-
Drive the vehicle at a vehicle speed of 25 km/h (16 mph) or more for 20 seconds, and then drive the vehicle at a vehicle speed of less than 5 km/h (3 mph) for 20 seconds.
|
B2283
|
Vehicle Speed Sensor Malfunction
|
Either of the of the following malfunctions is detected (a vehicle speed sensor malfunction is detected) (1-trip detection logic*):
-
Vehicle speed signal malfunction detection 1: Excessive deceleration is detected
-
Vehicle speed signal malfunction detection 2: Engine speed linked malfunction detected
|
-
Meter/gauge system
-
Vehicle stability control system
-
Certification ECU (smart key ECU assembly)
-
Wire harness or connector
|
DTC Output Confirmation Operation:
-
Run the engine at an engine speed of 2000 rpm or more for 300 seconds.
-
Drive the vehicle at a vehicle speed of 50 km/h (31 mph) or more for 10 seconds, and then drive the vehicle at a vehicle speed of less than 50 km/h (31 mph).
|
-
*: Only detected while a malfunction is present and the engine switch is on (IG).

Fail-safe Function when Malfunction Detected
|
B2282
|
-
When the signal sent via either direct line or CAN communication is malfunctioning and indicates that the vehicle speed is 0 km/h (0 mph), there is no effect on vehicle behavior.
-
When the signal sent via either direct line or CAN communication is malfunctioning and indicates that the vehicle is moving, the engine switch cannot be turned from on (IG) to off.
|
-
|
B2283
|
-
The power source mode is changed to off (the engine is stopped) by pressing the engine switch while the vehicle is being driven.
-
With the electrical key transmitter sub-assembly in the cabin, even if an engine start operation is performed, the engine will not start.
|
Steering lock motor operation is prohibited.
