INSPECTION PROCEDURE
NOTICE:
Inspect the fuses for circuits related to this system before performing the following 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 help determine if the vehicle was moving or
stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the
malfunction occurred.
- STP signal conditions can be checked using the Techstream.
* Connect the Techstream to the DLC3.
* Turn the engine switch on (IG).
* Turn the Techstream on.
* Enter the following menus: Powertrain / Engine / Data List / Stop Light Switch.
* Check the STP signal when the brake pedal is depressed and released.
