DTC B2282: Vehicle Speed Signal Malfunction; DTC B2283: Vehicle Speed Sensor Malfunction (TO 12/2010): Procedure

1. Drive the vehicle and check if the function of the speedometer in the combination meter is normal.

   OK

   Actual vehicle speed and the speed indicated on the speedometer are the same.

   HINT: 

   The vehicle speed sensor is functioning normally when the indication on the speedometer is normal.

NG → CHECK COMBINATION METER ASSEMBLY 

OK: Go to next step 

1. Delete the DTC. Refer to DTC CHECK / CLEAR .

   HINT: 

   After all DTCs are cleared, check if the trouble occurs again 320 seconds after the engine switch is turned on (IG).

2. Check for DTCs again.

   OK

   No DTC is output

OK → END 

NG: Go to next step 

1. Delete the DTC. Refer to DTC CHECK / CLEAR .

   HINT: 

   If the DTCs for the vehicle speed sensor malfunction are output, inspect those DTCs first. Refer to DIAGNOSTIC TROUBLE CODE CHART .

2. Check for DTCs again.

   OK

   No DTC is output

NG → GO TO  VEHICLE STABILITY CONTROL SYSTEM  VEHICLE STABILITY CONTROL SYSTEM 

OK: Go to next step 

1. Connect Techstream to the DLC3.

3. Measure the resistance according to the value(s) in the table below.

   Resistance

   Terminal No. (Symbol)	Specified Condition
   D44-19 (SPD) - E30-15	Below 1 Ω
   D44-19 (SPD) - Body ground	10 kΩ or higher

   HINT: 

   If the resistance between terminal SPD and body ground is less than 10 kΩ, there may be a short in a wire harness, connector, or ECU.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR AND EACH ECU 

OK: Go to next step 

1. After replacing the power source control ECU with a normally functioning ECU, check for power source control ECU DTCs.

   OK

   Power source control ECU DTCs are not output.

NG → GO TO  COMBINATION METER  COMBINATION METER SYSTEM 

OK → END (POWER SOURCE CONTROL ECU DEFECTIVE)
