ENTRY AND START SYSTEM(for Start Function), Diagnostic DTC:B2282

DTC Code DTC Name
B2282 Vehicle Speed Signal Malfunction

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.

DTC No. Detection Item DTC Detection Condition Trouble Area 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*)
  • AM2 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.

CAUTION / NOTICE / HINT

Note


  • When using the GTS with the power 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.

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

Tech Tips

When the cable is disconnected and reconnected to the negative (-) auxiliary 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 power 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.


      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) -
