Inspection Procedure

HINT: 

• Read freeze frame data using the Techstream. The ECM 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.
• Stop light switch conditions can be checked using the Techstream.
  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch on (IG).
  3. Turn the Techstream on.
  4. Enter the following menus: Powertrain / Engine / Data List / All Data / Stop Light Switch and ST1.
  5. Check the Data List indication when the brake pedal is depressed and released.
