DESCRIPTION DTC B2282 is
stored when the vehicle speed signal sent by the combination meter
assembly via direct line and the vehicle speed signal sent via CAN
communication do not match. DTC B2283 is stored when a malfunction in the vehicle speed sensor is detected.

Note | B2282 |
Vehicle Speed Signal Malfunction |
The
vehicle speed signal sent by the combination meter assembly via direct
line and the vehicle speed signal sent via CAN communication do not
match. (1-trip detection logic*) |
- Meter/gauge system
- Certification ECU (smart key ECU assembly)
- Wire harness or connector
|
- 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 |
Vehicle speed signal malfunction is detected (excessive deceleration is detected). (1-trip detection logic*) |
- Meter/gauge system
- Certification ECU (smart key ECU assembly)
- Wire harness or connector
|
- 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 power 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 power
switch cannot be turned from on (IG) to off.

B2283 |
- The power source mode is changed to off (the hybrid control system is
stopped) by pressing the power switch while the vehicle is being driven.
- With the electrical key transmitter sub-assembly in the cabin, even if a
hybrid control system start operation is performed, the hybrid control
system will not start.
| Steering lock motor operation is prohibited. | Related Data List and Active Test Items

CAUTION / NOTICE / HINT
NOTICE:
- When using the Techstream with the power switch off, connect the
Techstream to the DLC3 and turn a courtesy light switch on and off at
intervals of 1.5 seconds or less until communication between the
Techstream and the vehicle begins. Then select the vehicle type under
manual mode and enter the following menus: Body Electrical / Smart Key.
While using the Techstream, periodically turn a courtesy light switch on
and off at intervals of 1.5 seconds or less to maintain communication
between the Techstream and the vehicle.
- The smart key system (for Start Function, HV Model) uses the LIN
communication system and CAN communication system. Inspect the
communication function by following How to Proceed with Troubleshooting.
Troubleshoot the smart key system (for Start Function, HV Model) after
confirming that the communication systems are functioning properly.

PROCEDURE
1. | READ VALUE USING TECHSTREAM (VEHICLE SPEED METER) |
(a) Connect the Techstream to the DLC3. (b) Turn the power switch on (IG).
(c) Turn the Techstream on. (d) Enter the following menus: Body Electrical / Combination Meter / Data List.
(e) Read the Data List according to the display on the Techstream. Body Electrical > Combination Meter > Data List
Tester Display | Measurement Item |
Range | Normal Condition |
Diagnostic Note |
Vehicle Speed Meter | Vehicle speed |
Min.: 0, Max.: 255 | Almost same as actual vehicle speed (Speedometer tester) |
- | Body Electrical > Combination Meter > Data List
Tester Display | Vehicle Speed Meter |
HINT: Using a speedometer tester, check the actual vehicle speed and the vehicle speed displayed on the Techstream.
OK: Vehicle speed displayed on the Techstream is almost the same as the actual vehicle speed measured using a speedometer tester.
