PUSH-BUTTON START, 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.

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.

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 (1-trip detection logic*) do not match.

  • AM2 fuse

  • Meter/gauge system

  • Power management control ECU

  • Junction connector

  • Wire harness or connector

DTC Output Confirmation Operation:


  • Drive the vehicle for 20 seconds at a vehicle speed of 25 km/h (16 mph) or more, and then drive the vehicle at a vehicle speed of less than 5 km/h (3 mph) for 20 seconds.

Vehicle Condition and Fail-safe Function when Malfunction Detected
Vehicle Condition when Malfunction Detected Fail-safe Function when Malfunction Detected

  • 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.

Tech Tips


  • A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter assembly. The signal is changed to a pulse signal at the transistor in the combination meter assembly. Each ECU controls the respective system based on the pulse signal.

  • If a short occurs in an ECU, all systems in the diagram above will not operate normally.

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 push-button start uses the LIN communication system and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting Click here. Troubleshoot the push-button start after confirming that the communication systems are functioning properly.

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

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