DTC B2283: Vehicle Speed Sensor Malfunction: Procedure

1. Clear the DTC. Refer to DTC CHECK / CLEAR .
2. Check for DTC B2282 and DTC B2283.
   RESULT
   
   

   Result	Proceed to
   Only DTC B2283 is output	A
   Both DTC B2283 and DTC B2282 are output	B
   DTC is not output	C

   HINT: 

   If DTC B2282 and DTC B2283 are output, perform troubleshooting for DTC B2282 first.

B → See step   11 

C → See step   12 

A: Go to next step 

1. Check for DTC.

   HINT: 

   If vehicle stability control system DTCs are output, perform troubleshooting for vehicle stability control system DTCs.

A: Go to next step 

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 / Body / Data List.
5. Read the Data List according to the display on the Techstream.
