Turn the ignition switch ON (II).
Make sure the HDS communicates with the ECM/PCM. If it does not, go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING (PART 2) ).
Select the INSPECTION MENU with the HDS.
Do the TP LEARNING CHECK in the ETCS TEST. If needed, clean the throttle body (see THROTTLE BODY CLEANING ).
