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)
  • 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

Vehicle speed signal malfunction is detected (excessive deceleration is detected). (1-trip detection logic*)

  • Meter/gauge system
  • Certification ECU (smart key ECU assembly)
  • Harness or connector

DTC Output Confirmation Operation:

  • Drive the vehicle at a vehicle speed of 50 km/h (31 mph) or more for 10 seconds.
  • *: Only detected while a malfunction is present.

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.

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) 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) after confirming that the communication systems are functioning properly.
