DTC B2282: Vehicle Speed Signal Malfunction; DTC B2283: Vehicle Speed Sensor Malfunction [08/2015 - 08/2019]: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Body Electrical / Combination Meter / Data List.
5. According to the display on the Techstream, compare the actual vehicle speed with the Data List value.
   COMBINATION METER
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Vehicle Speed Meter	Vehicle speed/Min.: 0 km/h (0 mph), Max.: 255 km/h (158 mph)	Almost same as actual vehicle speed (Speedometer tester)	-

   OK

   The Data List value is approximately the same as the actual vehicle speed.

Result: 

NG 

GO TO METER/GAUGE SYSTEM (SPEED SIGNAL CIRCUIT) 

(Refer to Speed Signal Circuit [08/2015 - 08/2017] , or refer to Speed Signal Circuit [08/2017 - 08/2018] , or refer to Speed Signal Circuit [08/2018 - 08/2019] )

Result: 

OK 

See step  2

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Body Electrical / Power Source Control / Data List.
5. According to the display on the Techstream, read the Data List.
   POWER SOURCE CONTROL
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Vehicle Speed Signal	Vehicle moving or stationary/Stop or Run	Stop: Vehicle stopped Run: Vehicle moving at 5 km/h (3 mph) or more	-

   OK

   Stop (vehicle stopped) or Run (vehicle driven) appears on the screen according to the vehicle speed.

Result: 

OK

1. Disconnect the G39 power management control ECU connector.
2. Disconnect the G3 combination meter assembly connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   G39-23 (SPD) - G3-32 (+S)	Always	Below 1 Ω
   G39-23 (SPD) or G3-32 (+S) - Body ground	Always	10 kΩ or higher

Result: 

NG 

REPAIR OR REPLACE HARNESS OR CONNECTOR 

Result: 

OK 

See step  6

1. Using an oscilloscope, check the vehicle speed input signal waveform from the combination meter at the terminal of the power management control ECU.
