THEFT DETERRENT / KEYLESS ENTRY ENTRY AND START SYSTEM(for Start Function) B2282 Vehicle Speed Signal Malfunction B2283 Vehicle Speed Sensor 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*) | ·
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.
| DTC Code | Vehicle Condition when Malfunction Detected | 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 will not start. |
Steering lock motor operation is prohibited. |

CAUTION / NOTICE / HINT
- NOTICE:
- ·
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. 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.
·Before replacing the certification ECU (smart key ECU assembly), refer to the Service Bulletin.
·After repair, confirm that no DTCs are output by performing "DTC Output Confirmation Operation".
PROCEDURE
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Enter the following menus: Body Electrical / Combination Meter / Data List.
Read the Data List according to the display on the GTS.
- Body Electrical > Combination Meter > Data List

- HINT:
-
Using a speedometer tester, check the actual vehicle speed and the vehicle speed displayed on the GTS.
- OK:
The vehicle speed displayed on the GTS is almost the same as the actual vehicle speed measured using a speedometer tester.
- Result:
Proceed to OK NG
