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*)

  • AM2 NO. 3 fuse

  • Meter/gauge 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 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 detection

  • AM2 NO. 3 fuse

  • Meter/gauge 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.

  • *: 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 does not start.

Steering lock motor operation is prohibited.

CAUTION / NOTICE / HINT

Note:

  • When using the GTS with the engine switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start(CAN). While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.

  • The entry and start 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 entry and start system (for Start Function) after confirming that the communication systems are functioning properly.

  • Inspect the fuses of circuits related to this system before performing the following procedure.

  • Before replacing the certification ECU (smart key ECU assembly), refer to the entry and start system (for Start Function) Precaution.

  • After repair, confirm that no DTCs are output by performing "DTC Output Confirmation Operation".

Tip:

When the cable is disconnected and reconnected to the negative (-) battery terminal, the power source mode returns to the state it was in before the cable was disconnected.

PROCEDURE

  1. READ VALUE USING GTS (VEHICLE SPEED METER)

    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / Combination Meter / Data List.

    5. Read the Data List according to the display on the GTS.
