Scheme 403: PROCEDURE
  1. READ VALUE USING TECHSTREAM (VEHICLE SPEED) Drive the vehicle and check whether the operation of the speedometer in the combination meter assembly is normal. HINT: The vehicle speed sensor is operating normally if the speedometer reading is normal. If the speedometer does not operate, check it by following the procedure described for a speedometer malfunction. Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Powertrain / ECT / Data List / Vehicle Speed. Drive the vehicle. Read the value displayed on the Techstream. OK Vehicle speeds displayed on tester and speedometer display are equal. NG --> See step 2 OK --> See step 6

HINT

  1. The following troubleshooting flowchart is based on the premise that the engine is cranked normally. If the engine does not crank, proceed to the problem symptoms table.Refer to «PROBLEM SYMPTOMS TABLE [06/2012 - ]»(ref-598472-S12013296402014021400000) .
  2. Read freeze frame data using the Techstream. The TCM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.Refer to «FREEZE FRAME DATA [06/2012 - ]»(ref-598472-S37095654262014021400000) .

In this case, the freeze frame data output from the TCM has not been updated, so the data will not be useful for the inspection. However, reading the Data List as the first step in troubleshooting is effective to find malfunctions.
  3. The malfunction area can be checked using the Bus Check function on the Techstream.Refer to «DIAGNOSIS SYSTEM [06/2012 - ]»(ref-598642-S28836115522014021400000) .
